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.","tags":["crypto","ohlcv","candles","market-data","price"],"platforms":["bitcoin"],"tasks":["ohlcv"],"categoryId":"crypto-prices","priceUsd":0.005,"priceScheme":"exact","network":"eip155:8453","payTo":"0x6f60659390aDA1D02B14024d8c9d0C889f2F89c3","testnetOnly":false,"calls30d":null,"payers30d":null,"lastCalledAt":null,"startFeeUsd":null,"platformUsageExtra":null,"reportedSuccess30d":null,"pageUrl":null,"batchMax":null,"exampleCount":null,"unitsPerCharge":1,"unitBasis":"call","unitPriceUsd":0.005,"firstSeenAt":"2026-10-22T18:07:11.723Z","lastSeenAt":"2026-10-22T18:07:11.723Z","lastProbedAt":"2026-10-22T18:15:08.913Z","embeddedHash":"5c34f76d481abc6f73903204fe59ce2a183f523b83ec16074e80f57792c3747c"},"score":{"endpointId":"7d5d040f197eba9f","computedAt":"2026-10-22T19:46:15.347Z","score":null,"grade":null,"uptime7d":1,"latencyP50Ms":892,"probeCount7d":1,"flags":["no-usage-data"]},"recentProbes":[{"id":294714,"endpointId":"7d5d040f197eba9f","checkedAt":"2026-10-22T18:15:09.091Z","statusCode":402,"latencyMs":892,"valid402":true,"priceUsd":0.005,"payTo":"0x6f60659390aDA1D02B14024d8c9d0C889f2F89c3","error":null,"mcpOutcome":null,"mcpProtocol":null}],"siblings":{"total":3,"sameCategory":0,"rows":[{"id":"1514f800ed39c570","method":"GET","url":"https://x402-catalog-history.ai-business-surface.workers.dev/gas","categoryId":"onchain-data","priceUsd":0.001,"priceScheme":"exact"},{"id":"4753455e0120e433","method":"GET","url":"https://x402-catalog-history.ai-business-surface.workers.dev/markdown","categoryId":"web-extraction","priceUsd":0.01,"priceScheme":"exact"},{"id":"2b7b0a954103b17d","method":"GET","url":"https://x402-catalog-history.ai-business-surface.workers.dev/news","categoryId":"news","priceUsd":0.005,"priceScheme":"exact"}]},"tools":null,"source":{"name":"Hagglyai","url":"https://hagglyai.com/compare/crypto-prices","asOf":"2026-10-22T19:47:16.747Z"}}
