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 entry #62) via the x402 payment protocol. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of 20,000 base units, which equals $0.02 per request (USDC uses 6 decimals).
The endpoint is part of a broader platform (lowpaymentfee.com) that offers a variety of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request. The platform advertises no API keys, no rate limits, and instant access; callers simply attach an x402 payment header to each request.
Documentation is extremely sparse. The /docs, /pricing, /api, and /README pages all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what the audit logs endpoint actually returns beyond the generic label "Premium API Access." The specific purpose of audit log #62 — what data it contains, what fields are returned, or what input parameters it accepts — is unknown from the available material.

Quality
The endpoint is live (returns a valid 402 x402 challenge) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, and all documentation pages are empty stubs. The purpose of 'audit/logs/62' is unexplained, making this effectively a stub listing.
Warnings

- —No OpenAPI or schema describing request parameters or response format.
- —The specific meaning of 'audit/logs/62' is unknown; it is unclear what data is returned or what inputs are accepted.
