It is part of a broader platform offering dozens of pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all settled on the Base network using USDC.\n\nThe specific resource `/api/v1/audit/logs/11` is labeled \"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 is 20,000 base units of USDC (6 decimals), which equals $0.02 per request. The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` with a 300-second timeout window.\n\nThe platform advertises a simple pricing model of $0.02 per request across all endpoints, with no API keys, no rate limits, no minimums, and instant access. Documentation pages exist at `/docs`, `/pricing`, and `/api` but currently render only a \"Connect wallet\" prompt with no substantive content, so the actual schema of request bodies and response payloads for this audit-logs endpoint is unknown. The endpoint is confirmed live (returns a proper 402 challenge), but the lack of documentation about what data is returned or what parameters are accepted limits practical usability without experimentation.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","audit-logs","pay-per-request","no-api-key"],"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 pages all show only 'Connect wallet' with no content","Request body schema and response format for /api/v1/audit/logs/11 are completely unknown","The endpoint path references a specific log ID (11); it is unclear whether other IDs are available or what the data represents","The 'Premium API Access' label is generic and does not describe the actual functionality"],"endpointUrl":"https://lowpaymentfee.com/api/v1/audit/logs/11","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/11","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 402 challenge and clear pricing ($0.02 USDC on Base).
