Pricewatcha Api MCP Server

Pricewatcha API

The Pricewatcha API is the Structured Product Price Intelligence Platform for developers, automation and AI Agents.

The Pricewatcha API derives from the pricewatcha.com application. It provides price tracking, alerts and product intelligence beyond the Pricewatcha dashboard. This repository documents the public HTTP API, OpenAPI schema, official SDKs, MCP server and examples. It does not contain the production web application or scrapers.

Status: Public preview · Version: v1 (first release) · Base URL: https://pricewatcha.com/api/v1

Interactive API keys (browser): Developer page

---

Optional: verify connectivity with GET https://pricewatcha.com/api/v1/health. Then pick one of the three paths below.

Quickstart

Path 1: Browse prices (no auth)

Use demo product IDs from the demo catalog or search the catalog:

curl -s "https://pricewatcha.com/api/v1/products/demo_iphone_15_pro"
curl -s "https://pricewatcha.com/api/v1/search?q=iphone+15&limit=10"

Search matches product name, URL and platform/shop (case-insensitive). Results include the full Pricewatcha catalog, not only URLs submitted via POST /track. Use product_id from search for product and price-history endpoints (prod_* or demo_*).

Path 2: Track a product and get price history

curl -s -X POST "https://pricewatcha.com/api/v1/track" \
  -H "Content-Type: application/json" \
  -d '{"url": "https://www.backmarket.de/de-de/p/example-product"}'

curl -s "https://pricewatcha.com/api/v1/products/{productId}/price-history"

POST /track returns HTTP 200 with a bounded server-side long-poll (~25s). Use product_id from the response for price history.

Fast shops return status: "completed" with the full product in one call. Slow shops return status: "running" with a job_id. Poll GET https://pricewatcha.com/api/v1/jobs/{jobId} until the job is completed or failed. More detail: Async track & poll.

Path 3: Price alert with webhook (API key required)

Create a key on the Developer page, then:

curl -s -X POST "https://pricewatcha.com/api/v1/alerts" \
  -H "Authorization: Bearer pwk_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "product_id": "prod_a1b2c3d4e5",
    "min_threshold_price": 500.00,
    "webhook_url": "https://your-n8n-instance.com/webhook/abc",
    "notify_email": true
  }'

For authentication and data boundaries, see Authentication and Data boundaries.

---

Authentication

No credential required for catalog search, product detail, price history and async track/poll.

Protected API v1 endpoints (alerts, webhooks, authenticated track callbacks) use:

Authorization: Bearer pwk_live_…

Do not use the login session token for alerts, webhooks or other API v1 calls once you have an API key.

See Access model for which routes are public vs authenticated.

---

API keys (browser)

Log in on the Developer page to create and manage API keys in your browser. The full secret is shown once at creation.

For agents without a browser, use headless key bootstrap below.

Using your key on protected endpoints:

curl -s -X POST "https://pricewatcha.com/api/v1/alerts" \
  -H "Authorization: Bearer pwk_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"product_id": "prod_a1b2c3d4e5", "min_threshold_price": 499.00}'

---

Headless key bootstrap (for agents)

If an agent must obtain API credentials without a browser, authenticate once with the same email and password as on the website, create an API key, then use pwk_live_… for all further calls. This is not a separate agent login: it is the normal Pricewatcha account login exposed as an HTTP endpoint.

How login via API works

POST https://pricewatcha.com/api/auth/login accepts JSON email and password and returns a short-lived access_token (login session token). The Developer page login modal calls the same endpoint; in a script or agent you call it directly with curl or your HTTP client.

• You need an existing account (register on the site or via POST https://pricewatcha.com/api/auth/register).
• The email must be verified: otherwise the API returns 403.
• Wrong credentials return 401.
• Use access_token only to create keys; for alerts and webhooks use the pwk_live_… key from step 2.

Step 1: Login

curl -s -X POST "https://pricewatcha.com/api/auth/login" \
  -H "Content-Type: application/json" \
  -d '{"email": "you@example.com", "password": "YOUR_PASSWORD"}'

Response (HTTP 200), AuthResponse:

• access_token (string): login session token (JWT)
• token_type (string): always "bearer"
• user (object): id (string, UUID), email (string), email_verified (boolean)

{
  "access_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
  "token_type": "bearer",
  "user": {
    "id": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
    "email": "you@example.com",
    "email_verified": true
  }
}

Send the token as Authorization: Bearer <access_token> in step 2. Session tokens expire; do not store them as the long-term credential for an agent.

Step 2: Create API key

curl -s -X POST "https://pricewatcha.com/api/keys" \
  -H "Authorization: Bearer ACCESS_TOKEN_FROM_STEP_1" \
  -H "Content-Type: application/json" \
  -d '{"name": "agent bootstrap"}'

Response (HTTP 200), CreateApiKeyResponse:

• id (integer): key ID
• name (string): label from the request
• key_prefix (string): first 12 characters of the key (for display)
• key (string): full secret; returned only on create, not on list
• is_active (boolean)
• created_at (string, ISO 8601 datetime)
• last_used_at (string or null)
• revoked_at (string or null)

{
  "id": 42,
  "name": "agent bootstrap",
  "key_prefix": "pwk_live_ab",
  "key": "pwk_live_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
  "is_active": true,
  "created_at": "2026-05-27T14:30:00.123456",
  "last_used_at": null,
  "revoked_at": null
}

Store key securely. Use it on alerts, webhooks and other protected API v1 endpoints, not the session token from step 1.

API endpoints (overview)

Machine-readable contract: openapi/openapi.yaml · Live: GET https://pricewatcha.com/api/v1/openapi.json

---

Rate limits

Preview Limits (indicative)

The following limits apply during public preview and may change without notice.

Monitor X-RateLimit-Remaining and honor 429 with exponential backoff.

Limits group into Track (POST /track, stricter, to limit ingestion abuse) and Read (all other /api/v1/*, higher, for caching-friendly reads). Exact numbers may change during preview.

Headers

When rate limiting is active, responses may include:

HTTP 429

When limited, the API returns 429 Too Many Requests with a JSON body:

{ "detail": "Rate limit exceeded. Try again later." }

Agent guidance: honor 429, wait until X-RateLimit-Reset and reduce poll frequency on job status endpoints.

---

Async track and poll

POST /api/v1/track submits a product URL and waits up to ~25 seconds (long-poll).

• Fast shops: status: "completed" with full product in the same response
• Slow shops: status: "running" + job_id: poll GET /api/v1/jobs/{jobId} until completed or failed

Jobs are retained for 72 hours. After expiry, GET /jobs/{jobId} returns 404: use GET /products/{productId} instead.

Typical flows

Fast shop (one call)

POST /api/v1/track → { "status": "completed", "product": { ... } }

Slow shop

POST /api/v1/track → { "status": "running", "job_id": "job_xxx", "hint": "..." }
GET  /api/v1/jobs/{jobId} → poll until terminal state
GET  /api/v1/products/{productId} and .../price-history

Track a product

curl -s -X POST "https://pricewatcha.com/api/v1/track" \
  -H "Content-Type: application/json" \
  -d '{"url": "https://www.backmarket.de/de-de/p/example-product"}'

Response (200) when the scrape completes within the long-poll window:

{
  "job_id": "job_xxxxxxxx",
  "status": "completed",
  "product": {
    "product_id": "prod_xxxxxxxx",
    "name": "Example product",
    "shop": "Back Market",
    "current_price": 563,
    "currency": "EUR"
  },
  "error": null
}

Response (200) when still running after the long-poll timeout:

{
  "job_id": "job_xxxxxxxx",
  "status": "running",
  "product": null,
  "error": null,
  "hint": "Job still running. Call the get_job_status tool with this job_id to poll for the result."
}

Poll job status

curl -s "https://pricewatcha.com/api/v1/jobs/job_xxxxxxxx"

Completed response

{
  "job_id": "job_xxxxxxxx",
  "status": "completed",
  "product": {
    "product_id": "prod_xxxxxxxx",
    "name": "Example product",
    "shop": "Back Market",
    "current_price": 563,
    "currency": "EUR"
  }
}

Job states

Recommended client flow

1. POST /track with { "url": "..." } → 200
2. If running or queued, poll GET /jobs/{jobId} every 2–5 seconds
3. On completed, read product from the job or GET /products/{productId}
4. On failed, surface error.code; backoff before retrying

Job lookup vs. scrape failure

When polling GET /jobs/{jobId}, interpret HTTP status and body together:

A 404 is a lookup problem. A 200 with failed is a completed job whose scrape did not succeed.

Track job webhooks (push)

Authenticated clients can receive a push when a track job finishes: use callback_url (one-off) or webhook_id (existing subscription). Mutually exclusive. Same rate limits as anonymous POST /track.

curl -s -X POST "https://pricewatcha.com/api/v1/track" \
  -H "Authorization: Bearer pwk_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://www.backmarket.de/de-de/p/example-product",
    "callback_url": "https://n8n.example.com/webhook/track-done"
  }'

With callback_url, the track response may include callback_secret (whsec_…) once: same signing as subscription webhooks.

When the job finishes, Pricewatcha sends a webhook with event type track_job_completed or track_job_failed (same payload shape as other webhooks). If you do not use push delivery, you can still wait on POST /track (long-poll) or poll GET /jobs/{jobId} until the job reaches a terminal state.

Note: Anonymous POST /track with callback_url or webhook_id returns 400 auth_required_for_callback. MCP tools use track → poll (no callback_url in v1).

SDK convenience

Official Python and TypeScript SDKs may provide track_and_wait() / trackAndWait(): a helper that calls POST /track, then polls GET /jobs/{jobId} until the job is completed or failed and returns the result. The HTTP API stays async-first; the helper only saves you from writing the poll loop yourself. See SDKs.

Deduplication

Repeated POST /track for the same URL may return completed quickly with existing intelligence.

Timeouts

Long-poll default is ~25 seconds. For slow shops, poll GET /jobs/{jobId} instead of extending the track timeout.

---

Search

Keyword search is case-insensitive and matches product name, URL, platform/shop and related fields. Results cover the full Pricewatcha catalog, not only URLs submitted via POST /track.

Endpoint

GET https://pricewatcha.com/api/v1/search?q=…&limit=…

Optional limit: default 50, maximum 200.

curl -s "https://pricewatcha.com/api/v1/search?q=iphone&limit=10"

Example response

[
  {
    "product_id": "demo_iphone_15_pro",
    "name": "Apple iPhone 15 Pro 128GB (Refurbished)",
    "shop": "Back Market",
    "product_url": "https://www.backmarket.de/de-de/p/example-iphone-15-pro",
    "current_price": 563,
    "currency": "EUR",
    "status": "active",
    "preview": true
  },
  {
    "product_id": "prod_a1b2c3d4e5",
    "name": "iPhone 15 Pro",
    "shop": "Swappie",
    "product_url": "https://swappie.com/de/p/iphone-15-pro/",
    "current_price": 505,
    "currency": "EUR",
    "status": "active"
  }
]

Use product_url for direct linking without an extra GET /products/{id} call.

Demo catalog (no scrape required)

Preview demo products are always available for integration testing:

curl -s "https://pricewatcha.com/api/v1/products/demo_iphone_15_pro"
curl -s "https://pricewatcha.com/api/v1/products/demo_iphone_15_pro/price-history"
curl -s "https://pricewatcha.com/api/v1/search?q=iphone+15+pro"

See the demo catalog on GitHub.

---

Data boundaries

Catalog price intelligence (current price, history, product metadata) is available without authentication. User-specific data (accounts, emails, alert settings, private watchlists) is never exposed through the public API.

Readable fields

• product_id, name, shop/platform, product URL
• Current price, currency, last checked, status
• Price history, historical low/high, average, trend
• Demo entries may include "preview": true

Search, product detail and price history return the same fields whether the product was added via dashboard, API, MCP or demo data.

Product IDs

Use product_id from search or a completed track job for GET /products/{productId} and .../price-history.

Webhook payloads

Deliveries include product-level event data only (prices, product IDs, event type), not user emails or account details. Verify authenticity with the subscription signing secret (whsec_...); see Webhooks.

Compliance

If you build on this API, disclose to your users that prices are informational and that merchant sites are authoritative.

---

Errors and error codes

Non-success responses use a structured error object. Inspect error.code: do not parse free-text message values.

Shape

{
  "error": {
    "code": "invalid_url_type",
    "message": "url looks like a search or listing page (query parameter 'k')",
    "http_status": 400,
    "retry_recommended": false,
    "retry_after_seconds": null
  }
}

Public / track / catalog codes

Authentication & API keys

Alerts & webhooks

Agent guidance

• Branch on error.code, not message.
• When retry_recommended is true, use exponential backoff and respect retry_after_seconds.
• HTTP 200 on GET /jobs/{jobId} with status: "failed" is a job failure, not a transport error.

Full schemas: live GET https://pricewatcha.com/api/v1/openapi.json and the OpenAPI spec on GitHub.

---

Price Alert API

Create price alerts that send email notifications and/or fire webhooks when a threshold is crossed.

Each tracked product has one alert record per user with optional:

• min_threshold_price: notify when price drops to or below
• max_threshold_price: notify when price rises to or above

At least one threshold is required.

All endpoints require an API key in Authorization: Bearer …. Full schemas: GET https://pricewatcha.com/api/v1/openapi.json (tag alerts).

Webhooks

Webhooks push signed HTTP POST requests when prices change, alert thresholds are crossed or authenticated track jobs complete.

Subscribe to event types globally or for a single product_id. Each event type is delivered as its own request.

Manage subscriptions via POST https://pricewatcha.com/api/v1/webhooks. Full schemas: GET https://pricewatcha.com/api/v1/openapi.json (tags webhooks, alerts).

Note: Target URLs must use HTTPS and must not resolve to private or internal IP ranges.

Signing and verification

Every delivery includes:

• X-Pricewatcha-Event-Id
• X-Pricewatcha-Event-Type
• X-Pricewatcha-Timestamp (Unix seconds)
• X-Pricewatcha-Signature (sha256=<hex>)

Signed string: "{timestamp}.{raw_body}" with HMAC-SHA256 and your webhook secret (whsec_…, shown once at subscription creation).

Warning: The webhook secret is shown only once. Store it securely: only secret_prefix is shown afterward.

Python

import hmac
import hashlib

def verify_pricewatcha_webhook(secret: str, timestamp: str, raw_body: bytes, signature: str) -> bool:
    expected = hmac.new(
        secret.encode("utf-8"),
        f"{timestamp}.{raw_body.decode('utf-8')}".encode("utf-8"),
        hashlib.sha256,
    ).hexdigest()
    return hmac.compare_digest(f"sha256={expected}", signature or "")

JavaScript (Node.js)

import crypto from "node:crypto";

function verifyPricewatchaWebhook(secret, timestamp, rawBody, signature) {
  const expected = crypto
    .createHmac("sha256", secret)
    .update(`${timestamp}.${rawBody}`)
    .digest("hex");
  const expectedHeader = `sha256=${expected}`;
  return crypto.timingSafeEqual(
    Buffer.from(expectedHeader),
    Buffer.from(signature || "")
  );
}

Delivery and retry

Failed deliveries retry up to 5 times: 1 min → 5 min → 30 min → 2 h → 12 h.

After 10 consecutive failures the subscription is auto-disabled.

AI Agents & MCP

Pricewatcha exposes a remote MCP endpoint: no local installation required. Connect your AI client with the URL below. Available tools include get_api_status, search_products, track_product, get_job_status, get_product and get_price_history.

https://mcp.pricewatcha.com

For step-by-step setup, see Claude, ChatGPT, n8n and Make below.

---

Claude

What it enables: Ask Claude to search for products, track prices, check price history, set alerts and manage webhooks, all in natural language, directly in Claude.ai or the Claude desktop app.

How to connect: Claude.ai (web)

Step 1: Open the Customize panel
Click Customize (sliders icon) in the left sidebar of Claude.ai or go to claude.ai/settings/connectors.

Step 2: Add a custom connector
Under Connectors, click + to add a new connector.

Step 3: Enter the MCP server URL
Enter a name (e.g. “Pricewatcha”) and paste:

https://mcp.pricewatcha.com

Click Add.

Step 4: Done
Pricewatcha appears in your connector list with read-only tools (get_api_status, get_job_status, get_product, get_price_history, search_products) and write tools (track_product). You can now use Pricewatcha in any Claude conversation.

Step 5: Configure tool permissions (optional)
Open the connector in your connector list (or return to claude.ai/settings/connectors) and expand Tool permissions.

For each tool — or for the whole Read-only / Write group — choose when Claude may call it:

For everyday price checks and searches, set the read-only tools (or the whole read-only group) to Always allow. For track_product, pick Always allow if you want friction-free tracking, or keep Require approval if you prefer to confirm before a product is tracked.

How to connect: Claude Desktop App

Same steps: Customize → Connectors → Add custom connector → paste https://mcp.pricewatcha.com. Tool permissions are configured the same way under Tool permissions in the connector settings.

Try:

• “Find me a refurbished iPhone 15 Pro under €550”
• “Track this product URL and show me the price history”
• “Set an alert for this product when it drops below €500”

Note: track_product is a write tool because it creates a tracking job in the background. It does not modify or delete existing data.

---

ChatGPT

What it enables: Search products, track prices, get price history, set price alerts and manage webhooks, directly in ChatGPT via MCP.

Prerequisite: Developer Mode (one-time)
Custom MCP connectors require Developer Mode: Settings → Advanced → enable Developer Mode. Available on Plus, Pro, Team, Business, Enterprise and Edu (not on the free plan). Pricewatcha tools only work while Developer Mode stays on.

Step 1: Go to Settings → Apps and click Add custom connector.

Step 2: Paste the MCP URL:

https://mcp.pricewatcha.com

Optional connector logo: PNG, max 10 KB. Download from https://pricewatcha.com/static/img/mcp/chatgpt-logo.png

Step 3: Authentication: Select OAuth. ChatGPT handles the flow; you may see a brief authorization prompt on first connect.

Step 4: Done. Example prompts:

• “Search for a refurbished iPhone 15 Pro under €550”
• “Track this product URL and show me the price history”

Warning: ChatGPT may show a DEV label on unverified third-party connectors. Pricewatcha only works while Developer Mode is enabled.

---

n8n

What it enables: Build automated price-monitoring workflows. Trigger actions when prices change or cross your alert threshold: no coding required.

Typical use case: When a tracked product drops below your threshold → send a Telegram, Slack or email notification with product name, shop, current price and alert name.

Note: A publicly accessible URL is only required if you run n8n locally (self-hosted on your own machine). If you use n8n Cloud or a server-hosted instance, your n8n webhook URL is already publicly accessible: skip the tunnel step.

Path A: n8n Cloud or server-hosted (no tunnel needed)

1. Create a Webhook node in n8n → copy the Production URL.
2. Create a Pricewatcha alert with webhook_url set to the n8n URL (see below).
3. Done: price_alert_triggered events are delivered when thresholds are crossed.

Path B: n8n self-hosted locally (tunnel required)

1. Start a Cloudflare Tunnel: cloudflared tunnel --url http://localhost:5678 (install with brew install cloudflared on macOS).
2. Copy the tunnel URL (e.g. https://abc123.trycloudflare.com).
3. Create a Webhook node in n8n → note the path (e.g. /webhook-test/abc123).
4. Combine: https://abc123.trycloudflare.com/webhook-test/abc123.
5. Use this as webhook_url in the Pricewatcha alert.

Create a price alert with webhook delivery

Requires an API key:

curl -s -X POST "https://pricewatcha.com/api/v1/alerts" \
  -H "Authorization: Bearer pwk_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "product_id": "prod_YOUR_PRODUCT_ID",
    "min_threshold_price": 600.00,
    "webhook_url": "https://YOUR_N8N_URL/webhook/YOUR_PATH",
    "notify_email": false,
    "name": "Price drop alert"
  }'

When the current price is at or below min_threshold_price, Pricewatcha sends a price_alert_triggered event with this payload shape:

{
  "event_id": "evt_...",
  "event_type": "price_alert_triggered",
  "occurred_at": "2026-05-26T20:32:07Z",
  "product": {
    "product_id": "prod_...",
    "name": "iPhone 15 Pro",
    "shop": "Swappie",
    "current_price": 559.00,
    "currency": "EUR"
  },
  "price": {
    "old_price": 559.00,
    "new_price": 559.00,
    "historical_low": 7.99,
    "historical_high": 649.00,
    "average_price": 570.44
  },
  "alert": {
    "alert_id": "77",
    "min_threshold_price": 600.00,
    "threshold_reached": "min",
    "name": "Price drop alert"
  },
  "metadata": {
    "source": "pricewatcha",
    "api_version": "v1"
  }
}

Recommended n8n workflow

1. Webhook node (trigger): receives the price_alert_triggered event.
2. IF node: filter: {{ $json.body.event_type }} equals price_alert_triggered.
3. Notification node: Email / Telegram / Slack with:
   • Product: {{ $json.body.product.name }}
   • Shop: {{ $json.body.product.shop }}
   • Current price: {{ $json.body.price.new_price }} {{ $json.body.product.currency }}
   • Alert name: {{ $json.body.alert.name }}

Test the connection

curl -s -X POST "https://pricewatcha.com/api/v1/webhooks/YOUR_WEBHOOK_ID/test" \
  -H "Authorization: Bearer pwk_live_YOUR_KEY"

Note: The test endpoint requires a webhook subscription (POST https://pricewatcha.com/api/v1/webhooks), not an alert.

Signature verification: Verify X-Pricewatcha-Signature (HMAC-SHA256) in production: see Webhook signing.

Alternative: use the HTTP Request node: GET https://pricewatcha.com/api/v1/search?q=… or GET https://pricewatcha.com/api/v1/products/PRODUCT_ID/price-history.

Make

What it enables: Same webhook-based automation as n8n: visual workflows without code.

1. Create a scenario with Custom webhook as trigger; copy the URL.
2. Create a Pricewatcha webhook subscription (same curl as the n8n guide, use your Make URL as target_url).
3. Add a Router on event_type.
4. Test with POST https://pricewatcha.com/api/v1/webhooks/{id}/test.

Make free plan: Up to 1,000 operations/month including webhooks, enough for personal price monitoring.

Smart home

Use price alert webhooks to drive automations: scenes, notifications or lighting when a tracked product hits your target price.

See Home Assistant and Loxone below.

---

Home Assistant

What it enables: Trigger automations when a Pricewatcha price alert fires.

Typical use case: Price below threshold → mobile notification, toggle input_boolean.good_deal or run a script.

Path A: Webhook trigger (recommended)

1. Add a Webhook trigger (e.g. webhook ID pricewatcha_price_drop → https://YOUR_HA_HOST/api/webhook/pricewatcha_price_drop).
2. Ensure the URL is reachable from the internet (Nabu Casa, reverse proxy or tunnel).
3. Create a Pricewatcha alert with that webhook_url (n8n guide shows the curl example).
4. In actions, use trigger.json.product.name, trigger.json.price.new_price, etc.

Example automation (YAML):

automation:
  - alias: "Pricewatcha price drop"
    trigger:
      - platform: webhook
        webhook_id: pricewatcha_price_drop
        allowed_methods: [POST]
        local_only: false
    action:
      - service: notify.notify
        data:
          title: "Price alert: {{ trigger.json.product.name }}"
          message: >-
            {{ trigger.json.product.shop }} ·
            {{ trigger.json.price.new_price }}
            {{ trigger.json.product.currency }}

Path B: REST sensor (poll)

rest:
  - resource: "https://pricewatcha.com/api/v1/products/prod_YOUR_PRODUCT_ID"
    scan_interval: 3600
    sensor:
      - name: "Tracked product price"
        value_template: "{{ value_json.current_price }}"
        unit_of_measurement: "EUR"

No API key required for read endpoints. Polling is simpler but less real-time than webhooks.

Signature verification: Validate X-Pricewatcha-Signature in production: see Webhook signing.

Loxone

What it enables: Receive price-alert webhooks on your Miniserver and drive programs from virtual inputs.

Typical use case: JSON webhook → virtual input ViPriceAlert pulses → lighting or push notification.

Path A: Virtual HTTP Input (recommended)

1. Add a Virtual HTTP Input in Loxone Config (POST from the internet if reachable).
2. Create a Pricewatcha alert with that webhook_url.
3. Use command recognition on the raw JSON; map values to your program.

Example patterns for price_alert_triggered (match exact spacing in the monitor):

See Loxone Command Recognition.

Path B: Poll current price

1. Virtual HTTP Output on a schedule.
2. GET https://pricewatcha.com/api/v1/products/prod_YOUR_PRODUCT_ID
3. Extract "current_price": \v via command recognition.

Remote access: Pricewatcha must reach your webhook URL over HTTPS: use Loxone Remote Connect or a reverse proxy.

SDKs

Official Python and TypeScript client libraries live in sdks/ on GitHub.

They support the async track → poll → read workflow. Use the OpenAPI schema or plain HTTP from any other language.

Python

from pricewatcha import Pricewatcha

client = Pricewatcha()  # public endpoints, no key needed

## With an API key (alerts, webhooks, …)
client = Pricewatcha(api_key="pwk_live_YOUR_KEY")

Install from the Python SDK on GitHub. Setup: sdks/python/README.md.

TypeScript

import { PricewatchaClient } from "@pricewatcha/sdk";

const client = new PricewatchaClient();  // public endpoints, no key needed

const authedClient = new PricewatchaClient({ apiKey: "pwk_live_YOUR_KEY" });

Install from the TypeScript SDK on GitHub. Setup: sdks/typescript/README.md.
