It is part of a broader platform offering 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, settled in USDC on the Base network.\n\nThe specific resource `/api/v1/audit/logs/52` is labeled \"Premium API Access\" in the x402 challenge. The endpoint accepts POST requests and returns JSON. Payment is handled inline: callers attach an X-PAYMENT header with a signed USDC payment of up to 20,000 base units (i.e., $0.02, since USDC uses 6 decimals). There are no API keys, no rate limits, and no upfront commitments — access is purely transactional.\n\nDocumentation on the site is extremely thin. The /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI spec, no request/response schema, and no example payloads available. The exact structure of the audit log response is unknown. The endpoint is confirmed live (returns a proper 402 challenge), but the lack of documentation makes it difficult to know what data is returned or what POST body (if any) is expected.","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","x402 API","pay-per-call API","USDC micropayment API","Base network API","lowpaymentfee","premium API access"],"warnings":["No documentation available — /docs, /pricing, /api, and /README all show only 'Connect wallet'","No OpenAPI or schema describing request body or response format","The specific resource '/api/v1/audit/logs/52' is not listed among the site's advertised APIs, raising questions about what data it actually returns","Audit log content and structure are completely unknown"],"endpointUrl":"https://lowpaymentfee.com/api/v1/audit/logs/52","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/52","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live and returns a valid x402 challenge, but documentation is essentially nonexistent — no OpenAPI spec, no request/response examples, and every doc page renders only 'Connect wallet'.
