It is part of a broader platform offering dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all gated behind the x402 payment protocol on the Base network.\n\nThe specific endpoint probed charges up to $0.02 per request (20,000 base units of USDC with 6 decimals) settled on-chain to a Base address. Payment is made via the x402 exact scheme: callers attach an `X-PAYMENT` header with a signed payment to the `payTo` address. No API keys, subscriptions, or rate limits are advertised — access is purely pay-per-use.\n\nDocumentation is extremely sparse. The landing page lists available endpoints and pricing, but the `/docs`, `/api`, `/pricing`, and `/README` pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema, and no usage examples. The purpose of the \"accounts/39/statements\" resource specifically is unclear — it could be a demo or a fixed account endpoint. Without documentation on request body format or response structure, integrators will need to experiment or contact the provider.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","pay-per-request","account-statements","json-response"],"categories":["finance","data"],"synonyms":["account statements API","x402 paid API","USDC micropayment API","lowpaymentfee","Base network API","pay-per-call endpoint","crypto payment API"],"warnings":["No OpenAPI or schema documentation available — request body format and response structure are unknown.","The endpoint path '/api/v1/accounts/39/statements' references a hardcoded account ID (39); unclear if this is a demo or a real resource.","All documentation pages (/docs, /api, /pricing, /README) render only 'Connect wallet' with no content.","The broader platform lists many endpoints but none have documented schemas or examples."],"endpointUrl":"https://lowpaymentfee.com/api/v1/accounts/39/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/39/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 402 challenge, confirming it works.
