Pay-per-call audit logs endpoint on Base via x402, settled in USDC at $0.02/request.
What it does
This x402-enabled endpoint at lowpaymentfee.com provides access to audit log data (specifically log ID 8) via a POST request. Payment is handled inline using the x402 protocol on the Base network, settling in USDC (contract 0x8335…2913). Each call costs a maximum of 20,000 base units of USDC, which equals $0.02 (two cents) given USDC's 6 decimal places.
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 (sentiment analysis, summarization, classification, embeddings), finance and crypto data (price feeds, exchange rates, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints on the platform are advertised at the same $0.02 per request price point, require no API keys, and claim no rate limits.
Documentation on the site is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no detailed description of what the audit logs endpoint returns. The x402 challenge confirms the endpoint is live and accepting payment-gated POST requests, but the actual data payload and response format remain unknown.

Quality
The x402 challenge confirms the endpoint is live and pricing is clear ($0.02 USDC on Base), but there is no documentation, no OpenAPI schema, no request/response examples, and the docs pages are empty. The actual functionality of the audit logs endpoint is entirely opaque.
Warnings
- —No API documentation available — docs, pricing, and README pages all show only 'Connect wallet' with no content
- —No OpenAPI or output schema provided; request body format and response structure are unknown
- —The specific endpoint path (/api/v1/audit/logs/8) suggests a hardcoded resource ID; unclear if this is parameterizable
- —Platform appears to be a demo or early-stage project with many advertised endpoints but no substantive documentation
