AML alerts endpoint on Base, pay-per-call via x402 with USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to AML (Anti-Money Laundering) alert data via a pay-per-request x402 protocol. The specific resource `/api/v1/aml/alerts/42` returns JSON data related to AML alert ID 42. Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The provider, lowpaymentfee.com, hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced at $0.02 per request. However, the AML alerts endpoint is not listed on the provider's public landing page among the advertised API categories. This specific endpoint appears to be part of an unlisted or less-documented AML compliance service. No OpenAPI schema, request/response examples, or detailed documentation were found for this endpoint — the docs, pricing, and API pages all returned only a "Connect wallet" prompt with no substantive content.
The endpoint is confirmed live: it returns a proper HTTP 402 x402 challenge when called via POST. The payment challenge specifies the exact scheme on Base network, paying to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 using USDC contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, with a 300-second timeout. The output schema indicates it accepts HTTP POST requests and is discoverable.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no OpenAPI schema, no request/response examples, and no documentation beyond the payment challenge. The AML alerts endpoint is not listed on the provider's public landing page, and all doc pages returned only a wallet-connect prompt. Effectively a stub listing with confirmed liveness.
