It is part of a broader platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure utility APIs — all gated behind the x402 payment protocol on the Base network.\n\nThe endpoint returns a 402 Payment Required challenge requesting payment of up to 20,000 base units of USDC (0x8335…2913 on Base, 6 decimals), which equals $0.02 per request. Payment is settled on-chain to `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3`. The response MIME type is `application/json`. No API keys are required; access is granted immediately upon valid x402 payment. The platform advertises no rate limits and a flat $0.02/request pricing model across all its endpoints.\n\nDocumentation is extremely sparse — the docs, pricing, API, and README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The specific data returned by the `/accounts/31/statements` endpoint (e.g., what kind of account, what statement fields) is not documented anywhere in the crawled material. The endpoint is live and responding with a valid x402 challenge.","tags":[],"capabilities":["x402-payment","usdc-base","account-statements","json-response","no-api-key","per-request-billing"],"categories":["finance","data"],"synonyms":["account statements API","financial statements","x402 API","pay-per-call API","Base USDC API","lowpaymentfee","micropayment API"],"warnings":["No API documentation available — docs, pricing, API, and README pages all show only 'Connect wallet' with no content","No request or response schema documented; unclear what data the /accounts/31/statements endpoint returns","The endpoint path includes a hardcoded account ID (31), suggesting it may be a demo or single-tenant resource","No OpenAPI spec or ai-plugin manifest found"],"endpointUrl":"https://lowpaymentfee.com/api/v1/accounts/31/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/31/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, but documentation is essentially nonexistent — no request/response schemas, no examples, no explanation of what 'accounts/31/statements' actually returns.
