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/89`. 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 gated by the x402 payment protocol on the Base network.
The specific endpoint probed (`/api/v1/aml/alerts/89`) returns a 402 challenge requesting payment in USDC (contract `0x8335…2913` on Base). The `maxAmountRequired` is 20,000 base units, which at 6 decimals equals $0.02 per request — consistent with the site's advertised flat pricing of $0.02/request across all endpoints. Payment is made via the x402 "exact" scheme, settling directly on-chain to the provider's wallet. No API keys or rate limits are advertised; access is purely payment-gated.
The endpoint accepts HTTP POST requests and returns `application/json`. However, the specific AML alert endpoint (`/api/v1/aml/alerts/89`) is not listed on the provider's homepage among the advertised API categories, and no documentation, request schema, or response schema is available for it. The docs, pricing, and README pages all render only a "Connect wallet" prompt with no substantive content. Without documentation or example responses, the actual data returned by this endpoint is unknown.
