AML alerts endpoint with per-request USDC payment on Base via x402 protocol.
What it does
This endpoint at lowpaymentfee.com provides access to AML (Anti-Money Laundering) alert data at the path `/api/v1/aml/alerts/16`. It is part of a broader platform offering various API categories including data & analytics, AI/ML, finance & Web3, and infrastructure utilities, all payable per-request via the x402 protocol on the Base network using USDC.
The specific endpoint probed (`/api/v1/aml/alerts/16`) returns an x402 challenge requesting payment of up to 20,000 base units of USDC (0x8335…2913 on Base). Since USDC uses 6 decimals, this translates to $0.02 per request, consistent with the platform's advertised flat pricing of $0.02/request across all endpoints. Payment is settled on-chain to the specified wallet address, with a 300-second timeout window. The endpoint accepts POST requests and returns `application/json`.
The platform advertises no API keys, no rate limits, and instant access. However, documentation is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what the AML alerts data actually contains or what parameters the POST body expects. The `/16` path segment suggests retrieval of a specific alert by ID, but this is inference only.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no documentation of request parameters or response format, and no examples. The AML alerts endpoint is not even listed on the homepage's API catalog. The actual functionality is entirely opaque.
