It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with an exact-payment scheme.\n\nThe specific endpoint `/api/v1/audit/logs/19` is listed under the provider's \"Premium API Access\" label. The broader lowpaymentfee.com platform advertises a suite of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no commitments required. The x402 challenge for this endpoint advertises a maxAmountRequired of 20,000 base units of USDC (6 decimals), which equals $0.02.\n\nDocumentation on the site is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the actual data returned after payment is unknown. The audit logs endpoint does not appear in the homepage's listed API catalog, so its exact purpose and response format remain unclear.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","audit-logs","pay-per-call","no-api-key"],"categories":["data","infrastructure"],"synonyms":["audit log API","x402 API","pay-per-request API","USDC micropayment API","Base network API","lowpaymentfee","premium API access"],"warnings":["No API documentation available — /docs, /api, /pricing, and /README pages all show only 'Connect wallet'","No OpenAPI or schema definition found for request or response payloads","The /api/v1/audit/logs/19 endpoint is not listed in the homepage API catalog — its purpose and data format are unclear","Cannot verify what data is actually returned after successful payment"],"endpointUrl":"https://lowpaymentfee.com/api/v1/audit/logs/19","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/19","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 there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and the audit logs endpoint isn't even listed on the homepage catalog.
