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/88` returns JSON data related to AML alert ID 88. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of $0.02 per request (20,000 base units at 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The broader lowpaymentfee.com platform hosts a variety of x402-gated APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities, all priced uniformly at $0.02 per request. However, the specific endpoint listed here is scoped to AML alerts. The endpoint accepts POST requests and returns application/json responses.
Documentation is extremely sparse. The crawled /docs, /api, /pricing, and /README pages all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what fields the AML alert response contains or what parameters the POST body accepts. The endpoint is live (confirmed via 402 challenge), but the lack of documentation makes it difficult to use without experimentation.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing. However, there is no OpenAPI schema, no request/response examples, no documentation of the AML alert data model, and no information about what POST body parameters are accepted. The /docs and other pages are empty. This is effectively a stub listing.
