What it does

This x402-enabled endpoint at lowpaymentfee.com provides access to audit log records via a simple POST request. The specific resource `/api/v1/audit/logs/1` returns audit log data in JSON format, paid per-call using USDC on the Base network. The endpoint uses the x402 "exact" payment scheme, requiring a one-time micropayment of $0.02 (20,000 base units of USDC with 6 decimals) per request.

The broader lowpaymentfee.com platform advertises a wide catalog of pay-per-call APIs spanning data & analytics, AI/ML (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are listed at $0.02 per request with no API keys, no rate limits, and no minimum commitments. Payments settle on the Base L2 network in USDC (contract 0x8335…2913).

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 spec, no request/response schema documentation, and no usage examples available from the crawl. The audit logs endpoint is confirmed live (returns a proper 402 challenge), but the actual shape of the response data and accepted request body parameters are unknown.
