Pay-per-call audit logs endpoint on Base via x402, settled 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/2`. 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 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, using the USDC contract at `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`. The maximum timeout for payment settlement is 300 seconds.
Documentation beyond the landing page is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The specific behavior of the `/api/v1/audit/logs/2` endpoint (what audit logs it returns, what parameters it accepts, what the response structure looks like) is not documented anywhere in the crawled material. The endpoint is confirmed live via a valid 402 challenge response.

Quality
The endpoint is confirmed live with a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation of what the audit logs endpoint actually returns, and all doc pages render only 'Connect wallet'. This is effectively a stub listing with minimal usable information.
