AML alerts endpoint payable per-request via x402 on Base (USDC).
What it does
This endpoint at lowpaymentfee.com provides access to AML (Anti-Money Laundering) alert data at the path `/api/v1/aml/alerts/21`. It is part of a broader platform offering dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services. All endpoints use the x402 payment protocol, settling in USDC on the Base network.
The specific endpoint probed (`/api/v1/aml/alerts/21`) returns a 402 challenge requesting up to 0.02 USDC (20,000 base units with 6 decimals) per POST request. The platform advertises flat $0.02/request pricing across all its APIs with no API keys, no rate limits, and instant access. However, documentation beyond the landing page is essentially empty — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no substantive content.
Because there is no OpenAPI schema, no request/response examples, and no documentation describing what the AML alerts endpoint actually returns or what parameters it accepts, the practical utility for agents is limited. The endpoint is live and responds with a well-formed x402 challenge, but the lack of documentation means callers must discover the API contract through experimentation.

Quality
The endpoint is live and returns a valid x402 challenge, but there is zero documentation on request parameters, response schema, or what AML alert data is actually returned. Docs pages are blank. This is effectively a stub listing.
