The provider operates a broad suite of pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request and settled in USDC on the Base network. No API keys, rate limits, or subscriptions are required; callers simply attach an x402 payment header to each request.\n\nThe specific resource `/api/v1/audit/logs/46` is described generically as \"Premium API Access\" and returns JSON. Based on the path structure, it likely returns an audit log record identified by ID 46. The x402 challenge confirms the endpoint is live, accepts POST requests, and requires up to 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals) per call. Payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base mainnet.\n\nDocumentation is extremely thin — the docs, pricing, and API pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema, and no example payloads available. The endpoint's actual response format and the structure of audit log data are unknown beyond the declared `application/json` MIME type.","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 API","USDC micropayment API","Base network API","lowpaymentfee","premium API access"],"warnings":["No OpenAPI spec or schema available for request or response bodies","Documentation pages (/docs, /pricing, /api, /README) render only 'Connect wallet' with no technical content","The specific endpoint /api/v1/audit/logs/46 is not listed among the provider's advertised APIs on the homepage","Audit log content and structure are entirely unknown — response format is inferred only from mimeType: application/json"],"endpointUrl":"https://lowpaymentfee.com/api/v1/audit/logs/46","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/46","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The x402 challenge is live and confirms pricing and network details, but there is zero documentation beyond the landing page listing.
