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 entry #17) 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/17` 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 recipient address is `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3`, and the payment timeout is 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 they appear to require a wallet connection and contain no substantive content in the crawl. No OpenAPI schema, request/response examples, or detailed documentation were found, so the exact request body format and response structure for this audit logs endpoint are unknown.

Quality
The endpoint is live and returns a valid x402 402 challenge with clear pricing. However, there is no OpenAPI schema, no request/response examples, and the documentation pages are empty (wallet-gated). The specific purpose of 'audit/logs/17' is unclear beyond the generic 'Premium API Access' label, and this particular path does not appear in the site's own API listing.
Warnings
- —No OpenAPI or schema documentation available — request body format and response structure are unknown.
- —Documentation pages (/docs, /pricing, /api) appear wallet-gated and returned no useful content.
- —The endpoint path /api/v1/audit/logs/17 is not listed among the site's advertised APIs, raising questions about its intended use.
- —The 'audit/logs/17' naming suggests a specific log entry but the broader context (what audit logs cover) is undocumented.
