The specific endpoint at `/api/v1/ach/102` is listed as \"Premium API Access\" and accepts POST requests. Payment is made per-call with no API keys, no rate limits, and no upfront commitments.\n\nThe x402 challenge confirms the endpoint is live, accepting USDC (contract `0x8335…2913` 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. The payment scheme is \"exact\" with a 300-second timeout.\n\nThe broader lowpaymentfee.com platform advertises endpoints across several categories — data/analytics, AI/ML (sentiment, summarization, classification, embeddings), finance/Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). However, this specific endpoint (`/api/v1/ach/102`) falls under a path suggesting ACH (Automated Clearing House) functionality, which is not explicitly documented on the site's landing page. No OpenAPI schema, detailed documentation, or example request/response payloads are available for this or any other endpoint on the platform. The docs, pricing, and API pages all render only a \"Connect wallet\" prompt with no further content.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","pay-per-request","no-api-key","post-endpoint","ach"],"categories":["finance","infrastructure"],"synonyms":["ACH API","payment processing API","x402 endpoint","USDC micropayment API","low fee API","pay-per-call API","Base network API"],"warnings":["The /api/v1/ach/102 path is not listed on the site's landing page among advertised endpoints — its exact functionality is unknown.","No API documentation, request schema, or response schema is available for any endpoint on the platform.","The docs, pricing, and API pages render only 'Connect wallet' with no usable content.","ACH-related functionality may involve regulated financial services — verify compliance requirements before use."],"endpointUrl":"https://lowpaymentfee.com/api/v1/ach/102","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/102","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is confirmed live via a valid 402 challenge with clear pricing ($0.02 USDC on Base).
