Pay-per-call audit logs endpoint 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 entry 15) via the x402 payment protocol. It accepts POST requests and charges 0.02 USDC per call on the Base network. No API keys or rate limits are required; payment is handled inline via the X-PAYMENT header using the x402 exact payment scheme.
The provider operates a broader platform offering multiple API categories including data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request. This specific endpoint (/api/v1/audit/logs/15) appears to return audit log information in JSON format, though the exact response schema is not documented.
Payment settles to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base. The maximum timeout for payment verification is 300 seconds. No OpenAPI spec, detailed documentation, or example responses are available — the docs, pricing, and API pages all require wallet connection and provide no additional content.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear, but there is no OpenAPI spec, no response schema, no example payloads, and the documentation pages are empty (wallet-gated). The purpose of 'audit/logs/15' is unclear — it may be a demo or placeholder. Very limited information to assess actual utility.

- —The endpoint path '/api/v1/audit/logs/15' suggests a specific resource ID; unclear if this is a general-purpose endpoint or a fixed demo
