The provider operates a broad suite 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 at a flat rate of $0.02 per request. No API keys or rate limits are required; callers pay per request via the x402 protocol.\n\nThe specific endpoint `/api/v1/audit/logs/65` is labeled \"Premium API Access\" and accepts POST requests. The x402 challenge confirms it is live, requiring a maximum of 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals) paid to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base. The response MIME type is `application/json`. No detailed documentation, request body schema, or response schema is available beyond what the x402 challenge and the provider's landing page disclose. The broader site lists many other endpoints (analytics, AI, finance, utilities) at the same price point, but documentation pages returned only a \"Connect wallet\" prompt with no further content.","tags":[],"capabilities":["x402-payment","pay-per-request","audit-logs","usdc-base","json-response"],"categories":["data","infrastructure"],"synonyms":["audit log API","premium API access","x402 audit endpoint","pay-per-call API","lowpaymentfee","Base USDC API","audit trail"],"warnings":["No request body schema or response schema documented — callers must guess at the expected input and output.","Documentation, pricing, and README pages all render only 'Connect wallet' with no substantive content.","The specific meaning of 'audit/logs/65' (what data it returns, what log ID 65 represents) is not documented anywhere in the crawl.","The provider lists many endpoints but none have detailed docs; treat all with caution."],"endpointUrl":"https://lowpaymentfee.com/api/v1/audit/logs/65","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/65","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no OpenAPI schema, no request/response examples, and documentation pages are empty stubs ('Connect wallet' only).
