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/12`. It is part of a broader platform offering dozens of pay-per-request 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/12`) returns an x402 challenge requesting up to 20,000 base units of USDC (0.02 USD) per request. The platform advertises a flat $0.02/request pricing model across all its APIs with no API keys, no rate limits, and no minimum commitments. Payment is made via the x402 `exact` scheme, sending USDC to the specified payTo address on Base.
Documentation is extremely sparse — the docs, pricing, API, 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. The endpoint path suggests it retrieves a specific AML alert by ID (12), but the actual data format and input parameters are unknown. The platform appears to be a generic x402 API marketplace, but without documentation it is difficult to assess the quality or source of the underlying data.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no documentation, no OpenAPI schema, no request/response examples, and no explanation of what AML alert data is actually returned. The AML alerts path does not appear on the provider's own homepage listing. This is effectively a stub listing.
