The specific resource `/api/v1/accounts/12/statements` accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with a maximum cost of $0.02 per request (20,000 base units at 6 decimals).\n\nThe broader lowpaymentfee.com platform advertises a wide catalog of x402-gated APIs spanning data & analytics, AI/ML (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are listed at $0.02 per request with no API keys, no rate limits, and no minimum commitments.\n\nDocumentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no usage examples available. The endpoint is confirmed live (returns a valid x402 402 challenge), but the actual data returned after payment is unknown. The account ID \"12\" in the URL path appears to be a fixed resource identifier, and it is unclear whether other account IDs are available or what the statement data structure looks like.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","account-statements","json-response","per-request-pricing","no-api-key"],"categories":["finance","data"],"synonyms":["account statements API","financial statements endpoint","x402 paid API","USDC micropayment API","Base network API","pay-per-call API","lowpaymentfee"],"warnings":["No OpenAPI spec or request/response schema available","All documentation pages (/docs, /pricing, /api, /README) render only 'Connect wallet' with no content","The actual data returned after payment is completely undocumented","Account ID '12' is hardcoded in the URL; unclear if other accounts exist or what data is served","The broad catalog of endpoints listed on the homepage (AI, finance, utils) cannot be verified for functionality"],"endpointUrl":"https://lowpaymentfee.com/api/v1/accounts/12/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/12/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, but there is zero documentation on request parameters, response schema, or what 'account statements' actually contain.
