It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 6 decimals).\n\nThe endpoint is part of a broader platform offering multiple API categories including data & analytics, AI & machine learning (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints on the platform share the same $0.02/request pricing with no API keys, no rate limits, and no minimum commitments.\n\nDocumentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what the audit logs endpoint actually returns or what parameters it accepts. The specific functionality of this particular endpoint (audit logs for resource 77) is unclear beyond the generic \"Premium API Access\" label.","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.","No OpenAPI or request/response schema provided; request parameters and response format are unknown.","The specific meaning of 'audit/logs/77' is unclear — it may be a demo or placeholder resource.","Platform appears to be a generic multi-category API hub; actual data sources and quality are unverified."],"endpointUrl":"https://lowpaymentfee.com/api/v1/audit/logs/77","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/77","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live (returns a valid 402 x402 challenge) and pricing is clear ($0.02 USDC on Base).
