Pay-per-call audit logs endpoint on Base via x402, settling in USDC at $0.02/request.
What it does
This x402-enabled endpoint at lowpaymentfee.com provides access to audit log data at the path `/api/v1/audit/logs/40`. 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 priced uniformly at $0.02 per request and settled in USDC on the Base network.
The endpoint accepts POST requests and returns JSON. Payment is handled via the x402 protocol: callers include an `X-PAYMENT` header with a signed payment for 20,000 base units of USDC (i.e., $0.02, since USDC uses 6 decimals). The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base. No API keys, rate limits, or upfront commitments are required — access is purely pay-per-call.
The specific functionality of the `/api/v1/audit/logs/40` endpoint is not documented beyond its title "Premium API Access." Based on the URL path, it likely returns audit log entries (possibly filtered by an ID or page parameter of 40), but the exact request body schema and response format are not described in the available documentation. The provider's landing page and docs pages are largely placeholder content (showing only a "Connect wallet" prompt), so detailed usage guidance is unavailable.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no documentation for this specific endpoint's request/response schema, no OpenAPI spec, and the docs/pricing/README pages are all empty placeholders. The exact purpose of the audit logs endpoint is inferred from the URL path alone.
