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 ID 43) via the x402 payment protocol. It is one of many endpoints offered by the lowpaymentfee.com platform, which hosts a broad catalog of pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities. All endpoints on the platform share a uniform $0.02-per-request pricing model settled in USDC on the Base network.
The specific resource `/api/v1/audit/logs/43` is described as "Premium API Access" and accepts POST requests. Payment is handled inline via the x402 protocol: callers receive a 402 challenge containing payment parameters (payTo address, asset contract, max amount of 20,000 base units = $0.02 USDC), then submit an `X-PAYMENT` header with a signed payment to unlock the response. No API keys, rate limits, or upfront commitments are required.
Documentation beyond the landing page is extremely sparse — the /docs, /pricing, /api, 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 actual content and structure of the audit log data returned by this endpoint is unknown from the available material.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming it is operational. However, there is no OpenAPI spec, no request/response schema, no example payloads, and no documentation beyond a landing page listing. The actual data returned by this audit-log endpoint is completely undocumented. This is effectively a stub listing.
