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 at the path `/api/v1/audit/logs/20`. It is part of a broader platform offering dozens of API endpoints across data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no commitments required.
Payment is handled via the x402 protocol on the Base network using USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`). The probe confirmed a live 402 challenge with `maxAmountRequired` of 20000 base units, which at 6 decimals equals $0.02 USD per call. The endpoint accepts HTTP POST requests and returns `application/json` responses. Payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` with a timeout of 300 seconds.
Documentation is extremely sparse — the docs, pricing, and API 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 specific endpoint path (`/audit/logs/20`) suggests it may retrieve a specific audit log entry by ID, but this is speculative. The platform advertises many other endpoints (sentiment analysis, text summarization, geocoding, price feeds, etc.) all at the same $0.02 price point, but none have documented schemas either.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is zero documentation on what the audit logs endpoint accepts or returns. No OpenAPI schema, no examples, and all doc pages render only 'Connect wallet'. The purpose of this specific endpoint is unclear.
Warnings
- —No API documentation available — all doc pages render only a 'Connect wallet' prompt
- —No request or response schema provided; input parameters and output format are unknown
- —The meaning of '/audit/logs/20' (whether '20' is an ID, page size, or something else) is undocumented
- —The platform lists many endpoints but none appear to have published schemas or usage guides
