Pay-per-call audit log access on Base via x402, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to audit log data (specifically log entry #27) via the x402 payment protocol. 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 priced at $0.02 per request and settled in USDC on the Base network.
The specific resource `/api/v1/audit/logs/27` is labeled "Premium API Access" and accepts POST requests. Payment is handled inline: callers receive a 402 challenge containing the USDC asset address on Base (0x8335…2913) and a maxAmountRequired of 20000 base units, which equals $0.02 (USDC uses 6 decimals). No API keys or rate limits are advertised; access is gated purely by the x402 micropayment. The payment timeout is 300 seconds.
Documentation is extremely sparse — the docs, pricing, API, 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 log data actually contains or what fields the POST body expects. The endpoint is live (returns a valid 402 challenge), but the lack of documentation makes it difficult to use without experimentation.
