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 24) 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/24` is described as "Premium API Access" and accepts POST requests. Payment is handled inline: callers send an X-PAYMENT header containing a signed x402 payment for up to 20,000 base units of USDC (i.e., $0.02, since USDC uses 6 decimals). The endpoint returns JSON. No API keys or accounts are required — authentication and authorization are handled entirely through the on-chain payment challenge.
The platform advertises no rate limits, no minimums, and instant access. Documentation pages (/docs, /pricing, /README) appear to require a wallet connection and contain no additional crawlable content. There is no OpenAPI spec or detailed schema available, so the exact request body format and response structure for this audit-logs endpoint are unknown. The endpoint is live and returning a valid x402 402 challenge.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no OpenAPI spec, no documentation beyond a landing page listing, no request/response schema, and the specific purpose of 'audit/logs/24' is unclear. The docs, pricing, and README pages are gated behind wallet connection and yield no content.
