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 83) via the x402 payment protocol. It is part of a broader platform that offers 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/83` is described as "Premium API Access" and accepts POST requests. Payment is handled inline via the x402 protocol: callers attach an `X-PAYMENT` header with a signed USDC payment on Base. The maximum amount required is 20,000 base units of USDC (6 decimals), which equals $0.02 per request. The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` with a timeout of 300 seconds.
The platform advertises a simple pricing model of $0.02 per request across all endpoints, with no API keys, no rate limits, no minimums, and instant access. Documentation pages exist at `/docs`, `/pricing`, and `/api` but currently render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no detailed documentation available for this or any other endpoint on the platform. The actual data returned by this audit logs endpoint is unknown — the description "Premium API Access" is generic and does not clarify what audit log information is provided.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming it accepts payments. However, there is no OpenAPI schema, no request/response examples, and all documentation pages render only 'Connect wallet' with no content. The endpoint description is entirely generic ('Premium API Access') and the actual data returned is unknown. This is effectively a stub listing.
