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 request and settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/accounts/66/statements` accepts POST requests and returns JSON. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is made via the x402 exact scheme with no API keys or rate limits required — callers simply attach the X-PAYMENT header with a valid payment proof.\n\nDocumentation is extremely sparse. The crawled docs, pricing, and API pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI spec, no request/response schema documentation, and no usage examples available. The endpoint is confirmed live (402 challenge returned), but the actual data returned after payment and the expected POST body are unknown.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","account-statements","pay-per-request","no-api-key","json-response"],"categories":["finance","data"],"synonyms":["account statements API","financial statements endpoint","x402 API","USDC micropayment API","pay-per-call API","lowpaymentfee","Base network API"],"warnings":["No OpenAPI or schema documentation available — request body and response format are unknown","All documentation pages (docs, api, pricing, README) render only 'Connect wallet' with no content","The endpoint path references a specific account ID (66); it is unclear if this is a demo or production resource","The nature and source of the 'statements' data is undocumented"],"endpointUrl":"https://lowpaymentfee.com/api/v1/accounts/66/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/66/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 via a valid 402 challenge, and pricing is clear ($0.02 USDC on Base).
