It is part of a broader platform offering dozens of pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per call and settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/accounts/22/statements` accepts POST requests and returns JSON. The x402 challenge confirms it is live, requiring a maximum of 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals) per request. Payment is made via the x402 exact scheme to the specified payTo address, with a 300-second timeout window. No API keys or rate limits are advertised; access is granted purely through on-chain micropayment.\n\nDocumentation is extremely sparse. The docs, pricing, API, and README pages all render only a \"Connect wallet\" prompt with no additional content. There is no OpenAPI schema, no request/response examples, and no description of what fields the statements endpoint accepts or returns. The endpoint's purpose (account statements) is inferred solely from the URL path and the generic \"Premium API Access\" label. Prospective users should expect to experiment with the endpoint to discover its input/output contract.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","account-statements","pay-per-request","json-response","post-method"],"categories":["finance","data"],"synonyms":["account statements API","financial statements endpoint","x402 micropayment API","USDC pay-per-call","Base network API","lowpaymentfee","premium API access"],"warnings":["No API documentation available — docs, pricing, and README pages all show only 'Connect wallet' with no content","No OpenAPI or JSON schema describing request parameters or response format","The endpoint path includes a hardcoded account ID (22); it is unclear whether other account IDs are supported or what data is returned","Purpose of 'account statements' is inferred from URL path only; no authoritative description exists"],"endpointUrl":"https://lowpaymentfee.com/api/v1/accounts/22/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/22/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 no meaningful documentation beyond a landing page listing.
