All endpoints use the x402 payment protocol, settling in USDC on the Base network. The specific function of the `/api/v1/ach/115` path is not documented — the listing title is simply \"Premium API Access\" — so the exact data or service it returns is unclear. It may relate to ACH (Automated Clearing House) banking data given the URL path, but this is speculative.\n\nThe endpoint is live and returns a valid x402 challenge. Pricing is $0.02 per request (20,000 base units of USDC with 6 decimals = $0.02), consistent with the platform's uniform pricing across all listed APIs. The platform advertises no API keys, no rate limits, no minimums, and instant access. Payment is made via the x402 `exact` scheme to a specified wallet address on Base mainnet.\n\nDocumentation is extremely sparse. The docs, pricing, API, and README pages all render only a \"Connect wallet\" prompt with no additional content. There is no OpenAPI schema, no request/response examples, and no description of what this specific endpoint accepts or returns beyond `application/json`. Agents should be aware that without knowing the expected POST body or response format, integration requires experimentation or additional out-of-band information.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","pay-per-request","no-api-key","json-response","post-method"],"categories":["finance","infrastructure"],"synonyms":["ACH API","payment processing API","low fee API","x402 endpoint","USDC micropayment API","pay-per-call API","Base network API"],"warnings":["The specific function of /api/v1/ach/115 is unknown — no documentation exists beyond the generic title 'Premium API Access'.","All documentation pages (docs, pricing, API, README) render only 'Connect wallet' with no usable content.","No request or response schema is available; the expected POST body is entirely undocumented.","The 'ach' path segment suggests possible financial/banking data, which may fall under regulated categories — verify compliance before use."],"endpointUrl":"https://lowpaymentfee.com/api/v1/ach/115","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/ach/115","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is live and returns a valid x402 challenge, but there is zero documentation on what /api/v1/ach/115 actually does, what request body it expects, or what it returns.
