x402 pay-per-call APIs for AI agents. Store: https://softbot-studio.pages.dev/

Softbot Reader

Turns any public web page URL into clean markdown (title, main text, links) for LLM context. Use when an agent needs to read a web page without running a browser.

• Base URL: https://softbot-reader-mainnet.softbot.workers.dev
• POST https://softbot-reader-mainnet.softbot.workers.dev/v1/read — $0.003 — body {"url":"https://example.com"}
• Spec: https://softbot-reader-mainnet.softbot.workers.dev/openapi.json · Discovery: https://softbot-reader-mainnet.softbot.workers.dev/.well-known/x402

Softbot Token Check

Safety verdict (safe / caution / avoid) for a Solana SPL token with reasons: mint & freeze authority, token age, top-10 holder concentration (exchange/pool wallets excluded), metadata and liquidity. Use before trading, accepting or recommending a Solana token.

• Base URL: https://softbot-tokencheck-mainnet.softbot.workers.dev
• POST https://softbot-tokencheck-mainnet.softbot.workers.dev/v1/check — $0.01 — body {"mint":"DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263"}
• Spec: https://softbot-tokencheck-mainnet.softbot.workers.dev/openapi.json · Discovery: https://softbot-tokencheck-mainnet.softbot.workers.dev/.well-known/x402

Softbot Email Check

Email address and domain check: verdict (deliverable_likely / risky / invalid) from syntax, MX/A records, disposable-provider list, role address, free provider, typo suggestion, SPF/DMARC/DKIM and domain age. No SMTP mailbox probing. Use before sending to, signing up, or accepting an email address.

• Base URL: https://softbot-emailcheck-mainnet.softbot.workers.dev
• POST https://softbot-emailcheck-mainnet.softbot.workers.dev/v1/email — $0.002 — body {"email":"john@gmial.com"}
• POST https://softbot-emailcheck-mainnet.softbot.workers.dev/v1/domain — $0.002 — body {"domain":"example.com"}

Free trial

First 3 calls free per wallet, per tool (each of the 9 endpoints). No payment and no funds needed, just a free signature:

1. Call the endpoint normally. The HTTP 402 PAYMENT-REQUIRED header carries an x402 sign-in-with-x (SIWX, CAIP-122) challenge in extensions["sign-in-with-x"].
2. Sign it with your Solana (SIWS, ed25519) or EVM/Base (SIWE, EIP-191) wallet and retry with the SIGN-IN-WITH-X header (createSIWxPayload + encodeSIWxHeader from @x402/extensions/sign-in-with-x).
3. A free call returns x-trial: free and x-trial-remaining. After 3 successful calls you get a normal 402: pay as usual.

• Failed calls (4xx/5xx) do not use up a trial. A store-wide cap of 200 free calls/day applies; after that, normal pricing.
• The softbot-mcp MCP server does this automatically.

Payment (x402 v2)

• Network: Solana mainnet (solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp)
• Asset: USDC (EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v), scheme exact
• Pay to: 9csHbkGGeQqNxvtZw8hPnC34NCcmZoZXVTEGC1MiDNRE
• Facilitator: PayAI (https://facilitator.payai.network)
• Flow: call the endpoint without payment → HTTP 402 with a PAYMENT-REQUIRED header → retry with a PAYMENT-SIGNATURE header (any x402 v2 client does this automatically). Settlement details come back in PAYMENT-RESPONSE.
• Invalid input (4xx) and upstream failures (5xx) are not charged.

Client example

// npm i @x402/fetch @x402/svm @solana/kit
import { wrapFetchWithPaymentFromConfig } from "@x402/fetch";
import { ExactSvmScheme } from "@x402/svm/exact/client";
import { createKeyPairSignerFromBytes } from "@solana/kit";
import fs from "fs";
// Your own funded Solana keypair (needs a little USDC). Never commit it.
const signer = await createKeyPairSignerFromBytes(new Uint8Array(JSON.parse(fs.readFileSync(process.env.SOLANA_KEYPAIR))));
const pay = wrapFetchWithPaymentFromConfig(fetch, {
  schemes: [{ network: "solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp", client: new ExactSvmScheme(signer) }],
});
const r = await pay("https://softbot-reader-mainnet.softbot.workers.dev/v1/read", { method: "POST", headers: { "content-type": "application/json" }, body: JSON.stringify({"url":"https://example.com"}) });
console.log(r.status, await r.json());

Base USDC (Coinbase CDP)

All APIs also accept USDC on Base via the Coinbase CDP x402 facilitator, alongside Solana USDC (PayAI). Base payTo: 0xC68F3cCa31D50208ab4C933a38288938e0B21E63. The 402 response lists both payment options; pick either. Listed in the Coinbase x402 Bazaar.
