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 ID 61) 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 settled on the Base network using USDC.
The specific resource `/api/v1/audit/logs/61` 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 on Base. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02 USD. The platform advertises no API keys, no rate limits, and instant access — you pay per request with no subscriptions or commitments.
The endpoint returned a valid 402 challenge during probing, confirming it is live. However, documentation is extremely sparse: the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI schema, no request/response examples, and no description of what the audit log payload actually contains. The endpoint's purpose (audit logs) is inferred solely from the URL path; the platform's landing page does not list this specific endpoint among its advertised APIs. Prospective users should expect to experiment with the endpoint to discover its actual input requirements and output format.

Quality
The endpoint is live and returns a valid x402 402 challenge with clear pricing. However, there is no OpenAPI schema, no request/response examples, and no meaningful documentation — docs pages render only a wallet connect prompt.
