AML alerts endpoint paid 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/5`. 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 on the platform use the x402 payment protocol, settling in USDC on the Base network.
The specific endpoint probed (`/api/v1/aml/alerts/5`) returned a valid 402 challenge requesting 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 thin — 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 (5), but the actual data schema and input parameters are undocumented.
