The specific path `/api/v1/trades/45` suggests a finance/trading data endpoint, though the exact response payload is not documented. The provider operates a broader platform offering Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure utility APIs, all priced at $0.02 per request and settled in USDC on the Base network.\n\nThe endpoint accepts POST requests and requires an X-PAYMENT header conforming to x402 version 1. Payment is made in USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base) with a max amount of 20,000 base units ($0.02 given USDC's 6 decimals). There are no API keys, no rate limits, and no subscription commitments — each call is independently paid. The timeout for payment settlement is 300 seconds.\n\nDocumentation is extremely sparse. The crawled docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI schema, no example request/response bodies, and no detailed description of what the `/api/v1/trades/45` endpoint returns. The endpoint is confirmed live (returns 402 challenge correctly).","tags":[],"capabilities":["x402-payment","per-request-billing","usdc-settlement","base-network","post-method","no-api-key","no-rate-limit"],"categories":["finance","data"],"synonyms":["trades API","trading data","x402 endpoint","pay-per-call API","USDC micropayment API","Base network API","lowpaymentfee"],"warnings":["No documentation available — docs/pricing/README pages only show 'Connect wallet'","No OpenAPI or output schema describing the response format","The specific endpoint /api/v1/trades/45 is not listed on the provider's homepage; its exact purpose is unclear","No example request or response bodies available"],"endpointUrl":"https://lowpaymentfee.com/api/v1/trades/45","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://lowpaymentfee.com/api/v1/trades/45","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is confirmed live with a valid x402 challenge, but there is no documentation, no schema, no example responses, and no description of what the trades/45 endpoint actually returns.
