{"id":"c0814225-f503-4451-a286-7f4a69e3e7f5","shortId":"67Xpje","kind":"x402","title":"x402-gated account statements endpoint on Base, pay-per-request with USDC.","tagline":"x402-gated account statements endpoint on Base, pay-per-request with USDC.","description":"This endpoint at lowpaymentfee.com provides access to account statements via a POST request to `/api/v1/accounts/104/statements`. It is part of a broader platform (lowpaymentfee.com) that offers a variety of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all gated behind the x402 payment protocol on the Base network.\n\nThe specific endpoint probed here returns an x402 challenge requesting payment in USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` on Base) with a `maxAmountRequired` of 20,000 base units. 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 made via the x402 `exact` scheme to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3`, 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 substantive content. There is no OpenAPI schema, no request/response examples, and no description of what the account statements endpoint actually returns or what parameters it accepts. The endpoint path includes an account ID (104), but it is unclear whether this is a fixed demo account or a parameterized path. The lack of documentation makes it difficult to use this endpoint without experimentation.","tags":[],"capabilities":["x402-payment","usdc-payment","base-network","account-statements","pay-per-request","no-api-key"],"categories":["finance","data"],"synonyms":["account statements API","financial statements","x402 API","pay-per-call API","USDC micropayment API","lowpaymentfee"],"warnings":["No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no content","No OpenAPI or request/response schema provided; request parameters and response format are unknown","The endpoint path includes a hardcoded account ID (104); unclear if this is parameterized or fixed","Platform appears to list many endpoints but none have documented schemas or examples"],"endpointUrl":"https://lowpaymentfee.com/api/v1/accounts/104/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/104/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, but there is no documentation, no OpenAPI schema, no request/response examples, and no explanation of what the endpoint actually returns.
