It is part of a broader platform (lowpaymentfee.com) that offers a variety of x402-protocol pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all settled on the Base network using USDC.\n\nThe specific endpoint probed here returns an x402 challenge requesting up to 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals) per request, paid to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3`. The platform advertises a flat $0.02/request pricing model with no API keys, no rate limits, and instant access. The response MIME type is `application/json`.\n\nDocumentation is extremely sparse — the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI spec, no request/response schema documentation, and no examples available. The endpoint is live (402 challenge confirmed), but the actual data returned after payment and the expected POST body are unknown. The endpoint path suggests financial account statement data, but this cannot be verified from available materials.","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","x402 API","pay-per-call API","USDC micropayment API","lowpaymentfee","Base network API"],"warnings":["No API documentation available — all doc pages render only 'Connect wallet'","No OpenAPI or request/response schema provided","The endpoint path references a specific account ID (77); it is unclear whether this is parameterizable or a fixed demo","Actual response payload after payment is completely unknown","Platform appears to be a generic demo or showcase site with many listed endpoints but no substantive documentation"],"endpointUrl":"https://lowpaymentfee.com/api/v1/accounts/77/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/77/statements","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live and returns a valid x402 challenge, but documentation is effectively nonexistent — all doc pages show only 'Connect wallet'.
