Pay-per-call audit log access on Base via x402 — $0.02/request in USDC.
What it does
This endpoint at `/api/v1/audit/logs/75` is part of the lowpaymentfee.com platform, which offers a broad catalog of x402-enabled APIs spanning data analytics, AI/ML inference, finance, crypto, infrastructure utilities, and more. Each endpoint is priced at $0.02 per request, settled in USDC on the Base network with no API keys, no rate limits, and no commitments required.
The specific resource probed (`/api/v1/audit/logs/75`) is labeled "Premium API Access" and returned a valid x402 challenge with `maxAmountRequired` of 20,000 base units of USDC (0.02 USDC = $0.02). Payment is made via the x402 exact scheme to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3`. The endpoint accepts POST requests and returns `application/json`.
Documentation on the site is extremely thin — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema documentation, and no explanation of what the audit logs endpoint actually returns or what parameters it accepts. The endpoint is live (402 challenge confirmed), but the lack of documentation makes it difficult to know what data you will receive or what input is expected.

Quality
The endpoint is live and returns a valid x402 challenge, but there is zero documentation on request parameters, response schema, or what 'audit/logs/75' actually provides. Docs pages render only 'Connect wallet' with no content. No OpenAPI spec exists. The listing is effectively a stub.
Warnings

- —The purpose and data returned by /api/v1/audit/logs/75 is unknown — 'Premium API Access' is a generic label
- —The path segment '75' suggests a specific resource ID but its meaning is undocumented
