It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a per-request cost of $0.02 (maxAmountRequired of 20,000 base units at 6 decimals).\n\nThe provider lowpaymentfee.com hosts a broader suite of pay-per-call APIs spanning data & analytics (metrics, reports, data export, insights), AI & ML (sentiment analysis, text summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are advertised at $0.02 per request with no API keys, no rate limits, and no minimum commitments.\n\nThis specific endpoint (/api/v1/audit/logs/94) falls outside the categories listed on the landing page, and no dedicated documentation was found for it. The docs, API, pricing, and README pages all returned 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 log payload contains. The endpoint is confirmed live (402 challenge captured), but the lack of documentation makes it difficult to know what data is returned or what POST body (if any) is expected.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","audit-logs","pay-per-call","json-response"],"categories":["data","infrastructure"],"synonyms":["audit log API","x402 audit endpoint","pay-per-request API","USDC micropayment API","Base network API","lowpaymentfee audit"],"warnings":["No OpenAPI or schema documentation available for this endpoint","Docs, API, pricing, and README pages return only 'Connect wallet' with no content","The specific endpoint /api/v1/audit/logs/94 is not listed among the provider's advertised APIs on the landing page","No request body schema or response schema is documented — unclear what data is returned","Purpose of 'audit log 94' is entirely inferred from the URL path"],"endpointUrl":"https://lowpaymentfee.com/api/v1/audit/logs/94","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/94","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02/request in USDC on Base).
