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 85) 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, settled in USDC on the Base network.
The specific resource `/api/v1/audit/logs/85` is labeled "Premium API Access" and accepts POST requests. Payment is handled inline via the x402 protocol: callers attach an X-PAYMENT header with a signed USDC payment of up to 20,000 base units (i.e., $0.02 given USDC's 6 decimals) to the payTo address on Base. No API keys or accounts are required — authentication is purely payment-based. The endpoint returns JSON.
Documentation on the site is extremely thin. The docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no additional content. There is no OpenAPI spec, no request/response schema, and no explanation of what the audit log payload contains. The endpoint is confirmed live (returns a proper 402 challenge), but the actual data returned after payment is unknown. Prospective users should be aware that this is essentially a black-box endpoint with no documented input parameters or output format beyond the MIME type of application/json.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no documentation, no OpenAPI spec, no request/response schema, and no explanation of what data the audit log endpoint actually returns. The site's docs pages are empty. This is effectively a stub listing.
