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 and settled in USDC on the Base network.\n\nThe specific resource `/api/v1/audit/logs/58` 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 containing a signed USDC payment of up to 20,000 base units (i.e., $0.02, since USDC uses 6 decimals) to the payTo address on Base. No API keys, accounts, or rate limits are required — access is purely payment-gated.\n\nDocumentation on the site is extremely thin. The /docs, /pricing, /api, and /README pages all resolve to a near-empty \"Connect wallet\" stub, so there is no OpenAPI spec, request/response schema, or usage examples available. The exact shape of the audit log response and what input parameters the POST body expects are unknown. The endpoint is confirmed live (returns a valid 402 challenge), but the lack of documentation limits practical usability without experimentation.","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 API documentation available — /docs, /pricing, /api, and /README all return empty 'Connect wallet' pages","No OpenAPI or request/response schema provided; input parameters and response format are unknown","The specific endpoint /api/v1/audit/logs/58 is not listed on the provider's landing page among their advertised APIs","Purpose of 'audit log #58' is unclear — may be a demo or placeholder resource"],"endpointUrl":"https://lowpaymentfee.com/api/v1/audit/logs/58","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/58","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 402 challenge, confirming it exists and accepts payment.
