The specific resource `/api/v1/accounts/51/statements` is accessed via POST and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.\n\nThe broader lowpaymentfee.com platform advertises a wide catalog of x402-payable APIs spanning data & analytics, AI/ML (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation), all at the same $0.02/request price point. However, this specific listing covers only the account statements endpoint.\n\nDocumentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the statements endpoint accepts or returns. The endpoint is confirmed live via a valid 402 challenge, but the actual functionality and data format remain unclear.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","account-statements","json-response","post-method","no-api-key"],"categories":["finance","data"],"synonyms":["account statements API","financial statements","x402 paid API","USDC micropayment API","Base network API","pay-per-call API","lowpaymentfee"],"warnings":["No API documentation available — /docs, /pricing, /api, and /README pages all show only 'Connect wallet' with no content","No OpenAPI or input/output schema provided; request body format and response structure are unknown","The endpoint path references a specific account ID (51) with no explanation of what this account represents or whether other account IDs are valid","The broader platform claims many API categories (AI, finance, infrastructure) but none have documented schemas"],"endpointUrl":"https://lowpaymentfee.com/api/v1/accounts/51/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/51/statements","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is confirmed live via a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base).
