Pay-per-call audit logs endpoint on Base via x402, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to an audit logs resource (`/api/v1/audit/logs/59`) 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 priced at $0.02 per request with no API keys, no rate limits, and no commitments.
The specific endpoint probed (`/api/v1/audit/logs/59`) is live and returns a valid x402 challenge. Payment is settled on the Base network using USDC (contract `0x8335…2913`) with a maximum amount of 20,000 base units, which equals $0.02 (USDC uses 6 decimals). The endpoint accepts POST requests and returns `application/json`. The payment timeout is 300 seconds.
Note that the audit logs endpoint is not listed on the site's public landing page, which advertises analytics, AI, finance, and utility APIs. Documentation pages (`/docs`, `/pricing`, `/api`, `/README`) all returned minimal content (just a "Connect wallet" prompt), so there is no detailed schema or usage documentation available. The exact structure of the request body and response payload for this audit logs endpoint is unknown.
