It is part of a broader platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure utility APIs, all gated behind the x402 payment protocol on the Base network.\n\nThe specific endpoint probed charges up to 0.02 USDC per request (maxAmountRequired of 20,000 base units with USDC's 6 decimals). Payment is settled on-chain on Base using USDC (contract `0x8335…2913`) with the \"exact\" scheme. The platform advertises a flat $0.02/request pricing across all its endpoints, with no API keys, no rate limits, and instant access.\n\nDocumentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI spec, no request/response schema documentation, and no examples available. The endpoint is confirmed live (returns a proper 402 x402 challenge), but without documentation it is unclear what request body the POST expects or what shape the account statement response takes. The endpoint path suggests it returns financial statement data for a specific account (ID 56), but this is purely inferred from the URL structure.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","account-statements","pay-per-request","no-api-key"],"categories":["finance","data"],"synonyms":["account statements API","financial statements endpoint","x402 API","USDC pay-per-call","Base network API","lowpaymentfee","micropayment API"],"warnings":["No API documentation available — /docs, /pricing, /api, and /README pages all show only 'Connect wallet'","No OpenAPI or schema definition found for request or response payloads","The endpoint path references a hardcoded account ID (56); unclear if this is parameterizable or a demo","Purpose and data returned by this specific endpoint are inferred solely from URL structure"],"endpointUrl":"https://lowpaymentfee.com/api/v1/accounts/56/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/56/statements","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is confirmed live with a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base).
