Pay-per-call audit log retrieval on Base via x402, settled in USDC at $0.02/request.
What it does
This x402 endpoint at lowpaymentfee.com provides access to audit log data at the path `/api/v1/audit/logs/5`. It is part of a broader platform offering dozens of pay-per-call 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 endpoint accepts POST requests and returns JSON. Payment is handled via the x402 protocol: callers include an `X-PAYMENT` header with a signed payment of up to 20,000 base units of USDC (i.e., $0.02, since USDC uses 6 decimals). The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base, with a maximum timeout of 300 seconds. No API keys or rate limits are advertised; access is instant once payment is attached.
Documentation is extremely sparse. The crawled docs, pricing, and README pages all rendered only a "Connect wallet" prompt with no additional content. There is no OpenAPI schema, no request/response examples, and no description of what the audit log endpoint actually returns or what parameters it accepts. The specific resource path (`/audit/logs/5`) suggests retrieval of a particular log entry (ID 5), but this is inference only. The platform's landing page confirms the pricing model and lists sibling endpoints but provides no technical detail about any of them.

Quality
The endpoint is live and returns a valid x402 402 challenge with clear pricing. However, there is no OpenAPI schema, no request/response examples, and the docs pages are empty beyond a wallet-connect prompt. The specific purpose of the audit/logs/5 endpoint is unclear, making this effectively a stub listing.
Warnings
- —No API documentation available — docs, pricing, and README pages only show a 'Connect wallet' prompt
- —No OpenAPI or JSON schema describing request parameters or response format
- —The endpoint path /api/v1/audit/logs/5 is not listed among the advertised APIs on the landing page, so its purpose is uncertain
- —No request or response examples are available anywhere in the crawled material
