AML alerts endpoint with per-request x402 payment on Base via USDC.
What it does
This endpoint at lowpaymentfee.com provides access to AML (Anti-Money Laundering) alert data via a pay-per-request model using the x402 protocol. The specific resource `/api/v1/aml/alerts/45` returns JSON data related to AML alert ID 45. Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request. No API keys or rate limits are required; callers simply attach an x402 payment header to each POST request.
The broader lowpaymentfee.com platform advertises a wide range of API categories including data analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced uniformly at $0.02 per call. However, the AML alerts endpoint is not listed on the provider's landing page among the advertised APIs, which raises questions about its documentation status and whether it is a fully supported production endpoint or an internal/experimental resource.
The x402 challenge was successfully captured, confirming the endpoint is live and accepting payments. The payment scheme is "exact" with a maxAmountRequired of 20000 base units of USDC (6 decimals), equaling $0.02. The endpoint accepts POST requests and returns application/json. No OpenAPI schema, detailed documentation, or example responses were found in the crawl.

Quality
The x402 challenge confirms the endpoint is live and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no documentation for the AML alerts endpoint specifically, no example request/response payloads, and the endpoint is not even listed among the provider's advertised APIs. This is effectively a stub listing with confirmed liveness.
