It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of 20,000 base units, which equals $0.02 per request (USDC uses 6 decimals).\n\nThe endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request. The platform advertises no API keys, no rate limits, and instant access. However, the specific audit/logs endpoint is not listed on the provider's landing page among the advertised API categories, so its exact response schema and data content are unclear.\n\nDocumentation is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a \"Connect wallet\" prompt with no additional technical detail. There is no OpenAPI spec, no example request/response documentation, and no description of what the audit log data contains. The endpoint is confirmed live (returns a valid x402 402 challenge), but the lack of documentation means consumers must discover the response format empirically.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","audit-logs","pay-per-call","json-api"],"categories":["data","infrastructure"],"synonyms":["audit log API","premium API access","x402 endpoint","pay-per-request API","USDC micropayment API","Base network API","lowpaymentfee"],"warnings":["No OpenAPI or schema documentation available for this endpoint","The /audit/logs/95 path is not listed among the provider's advertised API endpoints","All documentation pages (/docs, /api, /pricing, /README) render only a 'Connect wallet' prompt with no technical content","Response format and audit log data structure are completely undocumented"],"endpointUrl":"https://lowpaymentfee.com/api/v1/audit/logs/95","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/95","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 example requests or responses, and no description of what audit log data is returned.
