It is part of a broader platform (lowpaymentfee.com) that offers a variety of x402-protocol pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities.\n\nThe specific endpoint probed returns a 402 challenge requesting payment of up to 20,000 base units of USDC (0x8335…2913 on Base network), which equals $0.02 per request (USDC uses 6 decimals). Payment is settled on-chain via the x402 \"exact\" scheme to address 0x1A2B…85F3. The platform advertises uniform $0.02/request pricing across all its endpoints, with no API keys, no rate limits, and no minimum commitments required.\n\nDocumentation is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The endpoint's purpose (\"account statements\") and expected input/output formats must be inferred from the URL path and the generic description \"Premium API Access.\" The platform appears to be a demonstration or early-stage deployment of x402-based micropayment APIs.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","pay-per-request","account-statements","post-endpoint"],"categories":["finance","data"],"synonyms":["account statements API","x402 micropayment API","USDC pay-per-call","lowpaymentfee","Base network API","crypto-paid API","402 payment required"],"warnings":["No OpenAPI or schema documentation available — request and response formats are unknown","All documentation pages (/docs, /api, /pricing, /README) return only 'Connect wallet' with no content","The endpoint path references a specific account ID (160), suggesting this may be a demo or placeholder rather than a general-purpose API","No examples or descriptions of what 'account statements' contain"],"endpointUrl":"https://lowpaymentfee.com/api/v1/accounts/160/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/160/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 402 challenge, but there is zero documentation on request/response schemas, no OpenAPI spec, and all doc pages are empty stubs.
