AML alerts endpoint with per-request x402 payment on Base (USDC).
What it does
This endpoint at lowpaymentfee.com provides access to AML (Anti-Money Laundering) alert data via the x402 payment protocol. The specific resource `/api/v1/aml/alerts/95` returns alert information in JSON format, gated behind a per-call USDC micropayment on the Base network.
The endpoint accepts POST requests and charges up to 20,000 base units of USDC (0.02 USD) per call, settled on-chain to a Base address. No API keys or rate limits are required — payment is handled entirely through the x402 `X-PAYMENT` header. The parent site lowpaymentfee.com hosts a broader catalog of pay-per-request APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services, all priced at $0.02 per request.
Documentation is extremely sparse. The crawled docs, pricing, and API pages all returned only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI schema, no request/response examples, and no description of what fields the AML alert response contains. The endpoint is live (returns a valid 402 challenge), but the actual data quality and schema of the AML alert payload are unknown.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming it exists and accepts payments. However, there is no OpenAPI schema, no request/response examples, no documentation beyond a wallet-connect prompt, and the AML alert content is completely undocumented. The listing is effectively a stub with only pricing and protocol details confirmed.
