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 76) 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 call, settled in USDC on the Base network.
The specific resource `/api/v1/audit/logs/76` 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 payment of up to 20,000 base units of USDC (i.e., $0.02, since USDC uses 6 decimals) to the payee address `0x1A2B...85F3`. The x402 challenge was confirmed live, returning a proper 402 response with version 1 of the protocol and a 300-second payment timeout.
Documentation on the site is extremely thin — 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 log payload contains or what parameters the POST body accepts. The endpoint appears functional based on the 402 challenge, but the lack of documentation makes it difficult to know what data is returned or how to structure a request body.

Quality
The x402 challenge is live and confirms the endpoint accepts payment, but there is zero documentation on request format, response schema, or what 'audit logs' actually contain. No OpenAPI spec, no examples, and all doc pages are empty. This is effectively a stub listing.
