Pay-per-call audit log access on Base via x402 — $0.02/request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to audit log data (specifically log ID 39) 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/39` is labeled "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 `0x1A2B...85F3` and the endpoint returns JSON.
The platform advertises a simple pricing model: $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 the audit logs endpoint is unknown — the description "Premium API Access" is generic and does not clarify what audit information is provided.

Quality
The endpoint is live (returns a valid 402 x402 challenge) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, no meaningful documentation (all doc pages show only 'Connect wallet'), and the endpoint's purpose ('audit logs') is vague with no detail on what data is returned. This is effectively a stub listing.
