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 logs (specifically the `/api/v1/audit/logs/30` path) via a POST request, paid per-call in USDC on the Base network. The endpoint returns a 402 challenge advertising a maximum cost of 20,000 base units of USDC (0.02 USD per request, since USDC uses 6 decimals). No API keys or rate limits are required — payment is handled entirely through the x402 protocol's X-PAYMENT header.
The broader lowpaymentfee.com platform advertises a wide catalog of pay-per-call APIs spanning data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance/Web3 data (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are listed at the same $0.02/request price point and settle on the Base network using USDC.
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 detailed description of what the audit logs endpoint actually returns. The endpoint is live and responds with a valid x402 challenge, but the lack of documentation makes it difficult to know what data to send or what response to expect.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but documentation is essentially nonexistent — no OpenAPI schema, no request/response examples, and no description of what the audit logs endpoint returns or what input it expects. The listing is effectively a stub.
