Api Endpoint

x402-catalog-history.ai-business-surface.workers.dev

OHLCV candles for one crypto pair from Coinbase Exchange in one GET: time, open, high, low, close and volume, newest first, with the source URL and fetch time. curl: GET /candles?pair=BTC-USD&granularity=3600&limit=24 (granularity 60|300|900|3600|21600|86400 seconds, default 3600; limit 1-300, default 24; pair defaults to BTC-USD). Response: {"pair":"BTC-USD","granularity_seconds":3600,"count":24,"candles":[{"unix":1792670400,"time":"2026-10-22T12:00:00.000Z","open":81656.69,"high":81816.21,"low":81605.44,"close":81746.7,"volume":95.50529109}],"source":{"name":"Coinbase Exchange","http_status":200,"latency_ms":210}}. The exchange is read once after payment; a pair it does not list is a 502 and is not charged. 0.005 USDC, no account, no key, one GET, one delivery. A purchase is two calls by design: this first call returns 402 with the price and the payment terms, and you then repeat the same request with the PAYMENT-SIGNATURE header to receive the 200 delivery.
