Pay-per-call audit log access on Base via x402, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to audit log data (specifically log entry #58) 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 and settled in USDC on the Base network.
The specific resource `/api/v1/audit/logs/58` is labeled "Premium API Access" in the x402 challenge. The endpoint accepts POST requests and returns JSON. Payment is handled inline: callers attach an X-PAYMENT header containing a signed USDC payment of up to 20,000 base units (i.e., $0.02, since USDC uses 6 decimals) to the payTo address on Base. No API keys, accounts, or rate limits are required — access is purely payment-gated.
Documentation on the site is extremely thin. The /docs, /pricing, /api, and /README pages all resolve to a near-empty "Connect wallet" stub, so there is no OpenAPI spec, request/response schema, or usage examples available. The exact shape of the audit log response and what input parameters the POST body expects are unknown. The endpoint is confirmed live (returns a valid 402 challenge), but the lack of documentation limits practical usability without experimentation.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming it exists and accepts payment. However, there is no OpenAPI spec, no request/response schema, no documentation beyond a landing page listing, and the specific purpose of 'audit/logs/58' is unclear. The docs pages are all empty stubs. This is effectively a stub listing.
