It is part of a broader platform that offers dozens of pay-per-request API endpoints spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no commitments.\n\nThe specific endpoint probed (`/api/v1/audit/logs/59`) is live and returns a valid x402 challenge. Payment is settled on the Base network using USDC (contract `0x8335…2913`) with a maximum amount of 20,000 base units, which equals $0.02 (USDC uses 6 decimals). The endpoint accepts POST requests and returns `application/json`. The payment timeout is 300 seconds.\n\nNote that the audit logs endpoint is not listed on the site's public landing page, which advertises analytics, AI, finance, and utility APIs. Documentation pages (`/docs`, `/pricing`, `/api`, `/README`) all returned minimal content (just a \"Connect wallet\" prompt), so there is no detailed schema or usage documentation available. The exact structure of the request body and response payload for this audit logs endpoint is unknown.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","audit-logs","pay-per-request","no-api-key","json-response"],"categories":["data","infrastructure"],"synonyms":["audit log API","pay-per-call API","x402 endpoint","USDC micropayment API","Base network API","lowpaymentfee","audit trail","request logging"],"warnings":["No API documentation available — /docs, /pricing, /api, and /README pages all return only a 'Connect wallet' prompt with no content.","The specific endpoint /api/v1/audit/logs/59 is not listed among the provider's publicly advertised APIs on the landing page.","Request body schema and response schema are completely unknown — no OpenAPI spec or examples provided.","Purpose and data content of 'audit/logs/59' is unclear; the '59' may be a specific resource ID."],"endpointUrl":"https://lowpaymentfee.com/api/v1/audit/logs/59","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/audit/logs/59","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","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 the audit logs endpoint is not even listed on the provider's landing page.
