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 returns a 402 challenge requesting payment of up to 20,000 base units of USDC (contract `0x8335…2913` on Base). Since USDC uses 6 decimals, this translates to $0.02 per request, consistent with the site's advertised flat pricing of $0.02/request across all endpoints. Payment is settled on-chain to address `0x1A2B…85F3` using the x402 \"exact\" scheme with a 300-second timeout.\n\nThe platform advertises no API keys, no rate limits, and instant access. However, documentation is extremely thin — the /docs, /api, /pricing, and /README pages all render only a \"Connect wallet\" prompt with no further technical content. There is no OpenAPI spec, no request/response schema documentation, and no usage examples. The purpose of the \"account statements\" resource at account ID 58 is unclear; it may be a demo or placeholder. Without documentation on what fields to send in the POST body or what the response contains, practical integration requires experimentation.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","pay-per-request","account-statements","post-endpoint"],"categories":["finance","data"],"synonyms":["account statements API","x402 paid API","USDC micropayment API","Base network API","lowpaymentfee","pay-per-call API","crypto-gated endpoint"],"warnings":["No documentation available — /docs, /api, /pricing, /README all show only 'Connect wallet'","No OpenAPI or schema describing request body or response format for this endpoint","The resource path '/api/v1/accounts/58/statements' references a specific account ID (58) with no explanation of what data it returns","The broader platform lists many endpoints but none have documented schemas"],"endpointUrl":"https://lowpaymentfee.com/api/v1/accounts/58/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/58/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.
