Pay-per-call audit log access on Base via x402 — $0.02/request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to audit log data (specifically log ID 67) via the x402 payment protocol. The provider operates a broad catalog of pay-per-request APIs 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 specific endpoint `/api/v1/audit/logs/67` is described generically as "Premium API Access" and returns JSON. It accepts POST requests and requires an X-PAYMENT header carrying a valid x402 payment proof. The x402 challenge confirms the endpoint is live, requesting up to 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals) per call, paid to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 on Base.
Documentation is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The audit logs endpoint is not listed on the provider's landing page among the advertised API categories, so its exact data content and input parameters are unknown. Users should expect to experiment or contact the provider for details.

Quality
The x402 challenge is live and confirms pricing and payment details, but there is no documentation, no OpenAPI spec, no request/response examples, and the specific audit-logs endpoint isn't even listed among the provider's advertised APIs. Effectively a stub listing.
