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 via a pay-per-request model using the x402 protocol. The specific resource `/api/v1/aml/alerts/51` returns JSON data related to AML alert ID 51, settled in USDC on the Base network. The endpoint accepts POST requests and requires no API keys or account setup — payment is handled inline via the X-PAYMENT header.
The x402 challenge confirms the endpoint is live and charges a maximum of 20,000 base units of USDC (0.02 USD per request, since USDC uses 6 decimals). The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base, with a timeout of 300 seconds. The provider's landing page lists a broad catalog of APIs across data analytics, AI/ML, finance, and infrastructure categories, all priced at $0.02 per request.
Note that the specific AML alerts endpoint is not listed on the provider's main landing page, and no documentation, request/response schema, or example payloads are available for this endpoint. The docs, pricing, and API pages all render only a "Connect wallet" prompt with no further content. The actual structure of the AML alert response and what input parameters the POST body expects are unknown.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is no documentation, no request/response schema, no examples, and the AML alerts endpoint is not even listed on the provider's own landing page. The docs pages are empty. This is effectively a stub listing with only the payment challenge as evidence of functionality.
