Key Features

Dual-Basis Kimchi Premium (Industry First)

• Both official USD/KRW basis (matches what exchanges display) and USDT real-trade basis (what arbitrage bots actually trade) in a single response
• The 0.3-1% gap between the two is the structural USDT premium itself — measurable, actionable
• Critical for AI trading agents: the official basis is misleading; only USDT basis reflects true arbitrage margin after capital movement costs
• No other Kimchi Premium API in the x402 ecosystem provides this dual-basis view

KR Sentiment (Unique — No Competitors Worldwide)

• Real-time Korean market sentiment delivered in English
• Combines exchange data (189+ tokens Kimchi Premium, warnings, volume spikes, deposit soaring) with Korean news context (Coinness Telegram, 6-hour window)
• Claude AI generates: sentiment (BULLISH/BEARISH/CAUTIOUS_FOMO/PANIC/GREED/UNCERTAIN), score (-1.0 to +1.0), English report, exchange signals, news context, sources
• Academic research validates: "Korean news sentiment predicts global crypto returns" (2026)
• 1-hour cache + lazy invocation + concurrency lock for cost efficiency

Global vs Korea Divergence

• Light tier: real-time premium between CoinGecko global price and Korean exchange (Upbit), with 1-2 sentence AI interpretation
• Deep tier: adds Korean news signals (Coinness Telegram, 24h keywords + sentiment score) and structured AI analysis with Korean market drivers, global context, action suggestion, and confidence level
• 25 supported symbols (BTC, ETH, XRP, SOL, ADA, DOGE, DOT, MATIC, LINK, AVAX, ATOM, UNI, LTC, NEAR, OP, ARB, APT, ALGO, FTM, SUI, TRX, BCH, ETC, HBAR, SHIB)

Arbitrage Scanner

• Real-time Kimchi Premium for every token traded on both Upbit and Binance (189+)
• Reverse premium detection (Korean discount = buy signal)
• Upbit vs Bithumb price gap scanner (domestic arbitrage)
• Market share tracking (Upbit vs Bithumb volume)

Exchange Alerts

• New listing / delisting detection (market list comparison every 60s)
• Investment warning flags (from Upbit official API)
• Caution flags: price fluctuations, volume soaring, deposit soaring, global price differences, small account concentration

Market Movers

• 1-minute price surge/crash detection (>1% in 60 seconds)
• Volume spike detection (24h change rate, >1B KRW volume)
• Top 20 tokens by trading volume

AI Market Read

• 12+ data sources combined: Kimchi Premium, stablecoin premium, FX rate, Upbit/Bithumb volume TOP 5, BTC funding rate, open interest, dominance, Fear & Greed, + exchange intelligence (180+ tokens)
• Claude AI generates: signal (BULLISH/BEARISH/NEUTRAL), confidence (1-10), summary, key factors, token-level alerts, risk warning

• Pay autonomously with USDC on Base, Polygon, or Solana — or RLUSD on XRPL
• Access without API keys, signups, or human approval

Discovery endpoint: https://api.printmoneylab.com/.well-known/x402
MCP server: https://mcp.printmoneylab.com/mcp
OpenAPI spec: https://api.printmoneylab.com/openapi.json

No additional setup required. The service is indexed in CDP Bazaar across all 16 endpoints.

Receipt Verification

Every paid response includes a signed receipt. Bots can verify receipt authenticity using the merchant's public key.

Public Key

Available at /.well-known/x402 manifest under receipt_signer.public_key: curl https://api.printmoneylab.com/.well-known/x402 | jq '.receipt_signer'

Verification (Python)

from eth_account import Account
from eth_account.messages import encode_defunct

receipt = response_json["receipt"]
payload = "|".join([
    receipt["id"], receipt["endpoint"], receipt["amount"],
    receipt["currency"], receipt["network"], receipt["tx_hash"],
    receipt["payer"], receipt["merchant"], receipt["issued_at"]
])
recovered = Account.recover_message(
    encode_defunct(text=payload),
    signature=receipt["signature"]
)
assert recovered.lower() == receipt["signer"].lower()
