Pay-per-call audit logs endpoint on Base via x402 — $0.02/request in USDC.
What it does
This x402-enabled endpoint at lowpaymentfee.com provides access to audit log data at the path `/api/v1/audit/logs/10`. It is part of a broader platform offering dozens of pay-per-request API endpoints spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities. All endpoints on the platform are priced at $0.02 per request, payable in USDC on the Base network with no API keys, rate limits, or commitments required.
The specific endpoint probed (`/api/v1/audit/logs/10`) accepts POST requests and returns JSON. The x402 challenge confirms it is live, requesting up to 20,000 base units of USDC (i.e., $0.02) per call, settled to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base. The platform advertises instant access with no authentication beyond the x402 payment header.
Documentation is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what the audit logs endpoint actually returns or what parameters it accepts. The endpoint's purpose and data format must be inferred entirely from its URL path and the generic platform description.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no documentation, no OpenAPI schema, no request/response examples, and no explanation of what the audit logs endpoint actually returns. The docs pages are empty beyond a wallet-connect prompt. This is effectively a stub listing.
Warnings
- —No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no content.
- —No OpenAPI or request/response schema provided; the data format and accepted parameters are unknown.
- —The specific purpose and contents of '/api/v1/audit/logs/10' (e.g., what 'logs/10' refers to) are unclear.
- —Platform appears to be a generic demo or showcase site; actual data quality and reliability are unverified.
