It is part of a broader platform offering dozens of x402-protocol pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request.\n\nPayment is handled via the x402 protocol on the Base network using USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`). The challenge advertises a `maxAmountRequired` of 20,000 base units, which at 6 decimals equals $0.02 USD. No API keys are required; callers simply attach an `X-PAYMENT` header with a valid x402 payment proof. The platform advertises no rate limits and instant access.\n\nThe specific endpoint listed here (`/api/v1/accounts/88/statements`) is labeled \"Premium API Access\" but its exact response schema and input parameters are undocumented. The crawled docs, pricing, API, and README pages all returned only a \"Connect wallet\" stub with no further documentation. Without schema details or example responses, the actual data returned by this endpoint remains unclear. The broader platform lists many endpoint categories but provides no OpenAPI spec or detailed documentation for any of them.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","account-statements","pay-per-request","no-api-key","post-method"],"categories":["finance","data"],"synonyms":["account statements API","financial statements endpoint","x402 paid API","USDC micropayment API","lowpaymentfee","pay-per-call API","Base network API"],"warnings":["No OpenAPI spec or schema documentation available for any endpoint on the platform","All documentation pages (/docs, /api, /pricing, /README) return only a 'Connect wallet' stub with no content","The specific endpoint path includes a hardcoded account ID (88); it is unclear whether this is parameterizable or a fixed demo","Response format and required POST body fields are completely undocumented"],"endpointUrl":"https://lowpaymentfee.com/api/v1/accounts/88/statements","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/accounts/88/statements","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 confirmed) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no documented input/output schema, no example responses, and all doc pages return only a wallet-connect stub.
