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 84) 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/84` 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 per call is 20,000 base units of USDC (6 decimals), which equals $0.02 USD. The platform advertises no API keys, no rate limits, and instant access — you pay per request and nothing more.
Note that while the platform homepage lists many endpoint categories (analytics, AI, finance, infrastructure), this specific listing covers only the `/api/v1/audit/logs/84` endpoint. The audit logs endpoint is not prominently listed on the homepage, so its exact response schema and data contents are unclear. Documentation pages (`/docs`, `/pricing`, `/README`) returned only a "Connect wallet" prompt with no substantive content during crawl.

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 response examples, no documentation (all doc pages returned only 'Connect wallet'), and the specific audit logs endpoint is not described on the homepage. The actual data returned is unknown.
Warnings
- —Documentation pages (/docs, /pricing, /README) contain no useful content — only a 'Connect wallet' prompt.
- —The /api/v1/audit/logs/84 endpoint is not listed on the homepage among the advertised APIs; its purpose and response format are unclear.
- —No OpenAPI spec or output schema is available; response structure must be discovered empirically.
- —The endpoint targets a specific log ID (84); it is unclear whether other log IDs are accessible or what data is returned.
