Pay-per-call audit log access on Base via x402 — $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to audit log data (specifically log entry 14) via the x402 payment protocol. 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, settled in USDC on the Base network.
The specific resource `/api/v1/audit/logs/14` is labeled "Premium API Access" and accepts POST requests. Payment is handled inline via the x402 protocol: callers attach an `X-PAYMENT` header containing a signed USDC payment of up to 20,000 base units (i.e., $0.02 given USDC's 6 decimals) to the payee address on Base. No API keys, accounts, or rate limits are required — access is granted per-payment.
The platform's landing page advertises a wide catalog of endpoints (metrics, reports, sentiment analysis, text summarization, classification, embeddings, price feeds, exchange rates, geocoding, validation, and more), all at the same $0.02 price point. Documentation pages beyond the landing page appear to require a wallet connection and contain no additional content. The exact schema of the audit log response is not documented, so callers should expect a JSON payload but cannot rely on a published output schema.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented request/response format, no examples, and the docs pages are empty beyond a wallet-connect prompt. The specific purpose of 'audit/logs/14' is not explained anywhere. This is effectively a stub listing.
