AML alerts endpoint with per-request USDC payment on Base via x402.
What it does
This endpoint at lowpaymentfee.com provides access to AML (Anti-Money Laundering) alert data at the path `/api/v1/aml/alerts/90`. It is part of a broader platform offering various pay-per-request APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services. All endpoints on the platform use the x402 payment protocol, settling in USDC on the Base network.
The specific endpoint probed (`/api/v1/aml/alerts/90`) returns an x402 challenge requiring payment of up to 20,000 base units of USDC (0.02 USD) per request. The platform advertises a flat $0.02 per request across all its APIs, with no API keys, no rate limits, and no minimum commitments required. Payment is made inline via the X-PAYMENT header using the x402 exact scheme.
Documentation on the site 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 endpoint actually returns or what parameters it accepts. The endpoint path includes a numeric ID (`90`), suggesting it retrieves a specific alert by ID, but this is purely inferred. The lack of documentation makes it difficult to assess the actual data quality or coverage of the AML alerting service.

Quality
The endpoint is live and returns a valid x402 challenge, confirming it exists and accepts payment. However, there is no documentation, no OpenAPI schema, no request/response examples, and no description of what AML alert data is actually returned. The docs pages are empty stubs. This is effectively a stub listing with only the x402 challenge and homepage listing to go on.
