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 settled on the Base network using USDC.\n\nThe specific endpoint `/api/v1/audit/logs/32` is categorized under \"Premium API Access\" and accepts POST requests. Payment is handled inline via the x402 protocol: callers attach an `X-PAYMENT` header containing a signed USDC payment on Base. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02 USD. The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` and the response MIME type is `application/json`.\n\nThe platform advertises a uniform $0.02/request pricing across all endpoints, with no API keys, no rate limits, no minimums, and instant access. Documentation pages (docs, pricing, README) were largely empty or gated behind a wallet connection, so detailed request/response schemas for this specific audit-log endpoint are not available. The endpoint is confirmed live — it returns a well-formed 402 challenge as expected by the x402 protocol.","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","premium API access","x402 API","pay-per-call API","USDC micropayment API","Base network API","lowpaymentfee"],"warnings":["No request or response schema available — the endpoint's exact input parameters and output format are unknown.","Documentation, pricing, and README pages return only a 'Connect wallet' prompt with no useful content.","The endpoint path '/api/v1/audit/logs/32' references a specific log ID (32); it is unclear whether this is a fixed demo resource or a parameterized path.","This endpoint is not listed on the provider's homepage among their advertised APIs, raising questions about its intended use."],"endpointUrl":"https://lowpaymentfee.com/api/v1/audit/logs/32","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/32","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is confirmed live with a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base).
