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 64) 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/64` 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 `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` with a 300-second timeout window.
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. However, documentation beyond the landing page is essentially empty (all doc/pricing/API pages only show a "Connect wallet" prompt), so the exact request body schema and response format for this audit logs endpoint are unknown. The endpoint is confirmed live — it returns a proper 402 challenge — but the lack of documentation means callers will need to experiment or contact the provider to understand the expected input and output formats.

Quality
The endpoint is confirmed live with a valid 402 challenge and clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no documentation of request/response formats, and all doc pages are empty beyond a wallet-connect prompt. The endpoint path suggests audit log retrieval but the actual functionality and data returned are unverified.
