All endpoints use the x402 payment protocol, settling in USDC on the Base network. The platform advertises a flat $0.02 per request with no API keys, no rate limits, and no minimum commitments.\n\nThe specific endpoint `/api/v1/ach/141` is listed under the title \"Premium API Access\" but its exact functionality is unclear — the path suggests ACH (Automated Clearing House) banking-related data or operations, but no documentation, request/response schema, or usage examples are available. The x402 challenge confirms the endpoint is live, accepts POST requests, and requires up to 20,000 base units of USDC (0.02 USDC, i.e., $0.02) per call on the Base network. Payment is made via the x402 `exact` scheme to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3`.\n\nThe provider's documentation pages (`/docs`, `/pricing`, `/api`, `/README`) all returned only a \"Connect wallet\" prompt with no substantive content, so the actual request format, expected input parameters, and response structure for this endpoint remain unknown.","tags":[],"capabilities":["x402-payment","usdc-base-network","pay-per-request","no-api-key","post-endpoint","ach-related"],"categories":["finance","infrastructure"],"synonyms":["ACH API","payment processing API","bank transfer API","lowpaymentfee","x402 USDC endpoint","automated clearing house","Base network API"],"warnings":["No documentation available — all doc pages return only 'Connect wallet' with no content","Exact functionality of /api/v1/ach/141 is unknown; 'Premium API Access' is a generic label","No request or response schema provided; callers cannot know what parameters to send or what to expect","The endpoint path suggests ACH banking operations but this is unconfirmed"],"endpointUrl":"https://lowpaymentfee.com/api/v1/ach/141","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/141","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is confirmed live via a valid x402 402 challenge, but there is no documentation, no request/response schema, no examples, and the endpoint's actual functionality (\"ACH/141\") is unexplained.
