AML alerts endpoint with per-request USDC payment on Base via x402 protocol.
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/61` returns JSON data related to AML alert ID 61. Payment is settled in USDC on the Base network.
The endpoint accepts POST requests and requires an X-PAYMENT header containing a valid x402 payment proof. The maximum amount required per request is 20,000 base units of USDC (6 decimals), which equals $0.02 USD. The provider advertises no API keys, no rate limits, and instant access. The payment timeout is 300 seconds.
The broader lowpaymentfee.com platform hosts a variety of x402-gated APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request. However, this specific endpoint is in the AML alerts category, which is not prominently listed on the landing page. Documentation beyond the landing page is extremely sparse — the docs, API, pricing, 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 detailed documentation for the AML alerts endpoint specifically.

Quality
The endpoint is live (returns a valid 402 x402 challenge) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, no documentation for the AML alerts resource, and the AML category isn't even listed on the landing page. The docs/pricing/README pages are all empty. This is effectively a stub listing.
