x402-gated audit log endpoint on Base, pay $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to an audit log resource (specifically log ID 97) behind an x402 paywall. The provider operates a broad suite of pay-per-call APIs 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. No API keys, rate limits, or upfront commitments are required; callers simply attach an x402 payment header to each request.
The specific endpoint `/api/v1/audit/logs/97` is labeled "Premium API Access" in the x402 challenge. The challenge confirms the endpoint is live, accepts POST requests, and requires up to 20,000 base units of USDC (0x8335…2913 on Base, 6 decimals → $0.02) per call. Payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout. The response MIME type is application/json.
Documentation beyond the landing page 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, and no description of what the audit log resource actually contains. The endpoint appears to be part of a larger platform offering many x402-gated APIs, but the specific functionality of this audit-logs endpoint is unclear from available materials.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no OpenAPI spec, no request/response schema, no documentation, and no description of what the audit log resource actually returns. The docs pages are empty beyond a wallet-connect prompt. This is effectively a stub listing.

- —All documentation pages (/docs, /api, /pricing, /README) render only 'Connect wallet' with no useful content
