The specific resource `/api/v1/accounts/27/statements` is a POST endpoint that returns JSON account statements. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) via the x402 \"exact\" scheme.\n\nThe endpoint charges a maximum of 20,000 base units of USDC per request. Since USDC uses 6 decimals, this translates to $0.02 per call, consistent with the site-wide pricing of $0.02/request advertised on the provider's landing page. No API keys are required; authentication and payment happen entirely through the X-PAYMENT header. The provider advertises no rate limits and instant access.\n\nThe provider (lowpaymentfee.com) hosts a broader catalog of x402-gated APIs spanning data/analytics, AI/ML (sentiment, 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 `/api/v1/accounts/27/statements` endpoint. Documentation beyond the landing page is extremely sparse — the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no substantive content.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","account-statements","json-response","no-api-key","per-request-billing"],"categories":["finance","data"],"synonyms":["account statements API","financial statements endpoint","x402 paid API","USDC micropayment API","Base network API","lowpaymentfee","pay-per-call API"],"warnings":["No API documentation available — docs, pricing, and README pages all show only 'Connect wallet' with no content.","The endpoint targets a hardcoded account ID (27); it is unclear whether this is a demo or a real resource.","No request body schema or response schema is documented anywhere.","No examples of actual response payloads are available to verify functionality."],"endpointUrl":"https://lowpaymentfee.com/api/v1/accounts/27/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/27/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 with clear pricing, but there is no OpenAPI schema, no request/response examples, and documentation pages are empty stubs.
