All endpoints use the x402 payment protocol, settling in USDC on the Base network. The specific function of the `/api/v1/ach/136` path is not documented — the listing title is simply \"Premium API Access\" and no schema, parameter descriptions, or example responses are provided. The \"ach\" path segment suggests it may relate to ACH (Automated Clearing House) banking or payment functionality, but this is speculative.\n\nPricing is $0.02 per request (20,000 base units of USDC with 6 decimals = $0.02), paid via the x402 exact-payment scheme. The platform advertises no API keys, no rate limits, no minimums, and instant access. Payment is made by including an X-PAYMENT header with a valid x402 payment proof. The endpoint accepts HTTP POST requests and returns `application/json`.\n\nDocumentation is extremely sparse. The docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no additional content. There is no OpenAPI spec, no request/response schema, and no usage examples available. The endpoint is confirmed live (returns a proper 402 challenge), but without knowing what data or service it actually provides, agents should treat this as a low-information listing.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","pay-per-request","no-api-key","http-post","json-response"],"categories":["finance","infrastructure"],"synonyms":["ACH API","payment API","lowpaymentfee","x402 endpoint","USDC micropayment API","Base network API","pay-per-call API"],"warnings":["No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no content","The specific function of /api/v1/ach/136 is unknown; 'Premium API Access' is a generic title","No request or response schema provided — callers cannot know what parameters to send or what to expect back","The 'ach' path segment may imply regulated financial (ACH banking) functionality — verify compliance requirements","This endpoint is not listed among the advertised APIs on the homepage, raising questions about its status"],"endpointUrl":"https://lowpaymentfee.com/api/v1/ach/136","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/136","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 no documentation, no OpenAPI spec, no request/response schema, and no description of what the endpoint actually does.
