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 ID 12) via the x402 payment protocol. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with a maximum cost of 20,000 base units (i.e., $0.02 given USDC's 6 decimals).
The provider operates a broader platform offering multiple API categories including Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no commitments required. The specific endpoint probed (/api/v1/audit/logs/12) is labeled "Premium API Access" and appears to serve audit log records.
Documentation is extremely sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI schema, no request/response examples, and no description of what fields the audit log response contains. The endpoint is confirmed live (returns a valid x402 402 challenge), but the actual payload structure is unknown.
