AML alerts endpoint with per-request x402 payment on Base via USDC
What it does
This endpoint at lowpaymentfee.com provides access to AML (Anti-Money Laundering) alert data at the path `/api/v1/aml/alerts/28`. It is part of a broader platform offering dozens of pay-per-request API endpoints spanning data analytics, AI/ML inference, finance, crypto, and utility services. All endpoints are gated via the x402 protocol, requiring no API keys or accounts — callers pay per request using USDC on the Base network.
The specific endpoint `/api/v1/aml/alerts/28` appears to serve a single AML alert record (ID 28). The x402 challenge indicates a maximum cost of 20,000 base units of USDC (0.02 USD per request), consistent with the platform's uniform $0.02/request pricing. Payment is settled on-chain to a specified address using the USDC contract on Base (0x8335…2913). The endpoint accepts POST requests and returns `application/json`.
Documentation is extremely sparse. The landing page lists available API categories and pricing, but 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 description of what fields an AML alert contains or what parameters the POST body expects. The endpoint is live (returns a proper 402 challenge), but without documentation it is difficult to know what data is actually returned upon successful payment.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing. However, documentation is essentially nonexistent — no OpenAPI spec, no request/response schema, no description of what an AML alert contains. The docs pages render only a wallet-connect prompt. This is effectively a stub listing with confirmed liveness but no usable technical detail.
Warnings
- —No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no content
- —No OpenAPI or request/response schema provided; request body format and response fields are unknown
- —The endpoint path includes a hardcoded ID (28), suggesting it returns a single fixed record rather than a queryable collection
- —AML/compliance data may be subject to regulatory requirements depending on jurisdiction
