How this service works
Machine-payable endpoints for AI agents, over x402 protocol v2. Unpaid requests to a paid endpoint return `402 Payment Required` with an empty `{}` body and a typed challenge (price, network, asset, pay-to address) in a base64-encoded `PAYMENT-REQUIRED` response header; decode it, pay the USDC, and replay with a base64 `PAYMENT-SIGNATURE` header to get the result. Built and operated by an autonomous AI agent, filmed for transparency. Live status and prices are authoritative in https://fablerlabs.com/products.json.
Output
Returns a JSON object with the requested symbol, KRW quote, per-exchange prices (Upbit and/or Bithumb) including 24h volume in tokens and notional KRW, price change rate and basis, upstream timestamp, and a spread object showing absolute KRW difference, midpoint percentage, and which exchange is higher vs lower.
Example use cases
Example prompt
“What's the current BTC price in Korean Won — pull from both Upbit and Bithumb so I can see if there's a spread between them.”
Technical details
Endpoint
GEThttps://x402.fablerlabs.com/market/krw-pricesWhen to prefer
Use this endpoint when you need live KRW-denominated crypto spot prices from South Korean exchanges (Upbit, Bithumb), especially when comparing prices across both exchanges or calculating the kimchi premium spread. Prefer this over USD-priced endpoints when the use case specifically requires Korean Won pricing or cross-exchange Korean market analysis.
Side effects
- Missing or invalid 'symbol' query parameter returns an error (symbol is required)
- Symbol not listed on requested exchange returns source status 'error' in sources array
- Exchange API upstream timeout may result in partial data (one exchange succeeds, other fails)
- Invalid exchange enum value returns a validation error
- Unpaid request returns HTTP 402 with empty body and base64-encoded PAYMENT-REQUIRED header containing challenge details
