The specific path `/api/v1/trades/14` suggests a trades-related 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 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 settled in USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base, with a maximum amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals). There are no API keys, no rate limits, and no subscription commitments — each call is independently paid.\n\nDocumentation is extremely sparse. The crawled docs, pricing, and README pages all render only a \"Connect wallet\" prompt with no additional technical detail. The output schema and response format for this specific trades endpoint are not documented anywhere in the available material.","tags":[],"capabilities":["x402-payment","per-request-billing","usdc-settlement","base-network","trades-data","post-method"],"categories":["finance","data"],"synonyms":["trades API","x402 trades","pay-per-call API","USDC API","Base network API","lowpaymentfee","crypto trades endpoint","micropayment API"],"warnings":["No documentation available for this specific endpoint's request or response format","The meaning of '/trades/14' (trade ID? category?) is unclear","All docs/pricing/README pages render only 'Connect wallet' with no technical content","Output schema and example responses are entirely undocumented"],"endpointUrl":"https://lowpaymentfee.com/api/v1/trades/14","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/14","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no documentation of request parameters, response schema, or what 'trades/14' actually returns.
