AML alerts endpoint payable per-request via x402 on Base with 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/41`. It is part of a broader platform that offers dozens of pay-per-call API endpoints spanning data analytics, AI/ML inference, finance, crypto, and utility services — all settled via the x402 protocol on the Base network using USDC.
The specific endpoint probed (`/api/v1/aml/alerts/41`) is live and returns a valid x402 402 challenge. The price advertised in the challenge is 20,000 base units of USDC (6 decimals), which equals $0.02 per request. The platform's landing page confirms a flat $0.02/request pricing model across all endpoints, with no API keys, no rate limits, and no minimum commitments required. Payment is made inline via the X-PAYMENT header using the x402 exact scheme.
Documentation is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical content. There is no OpenAPI spec, no request/response schema documentation, and no examples of what the AML alerts endpoint actually returns. The endpoint path suggests it retrieves a specific AML alert by ID (41), but the actual response format and input parameters are unknown beyond the fact that it accepts POST requests and returns `application/json`.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is zero documentation on request parameters, response schema, or what AML alert data is actually returned. The docs/pricing/README pages are all empty beyond a wallet connect prompt. Without any schema or examples, this is effectively a stub listing.
Warnings
- —No API documentation available — docs, pricing, and README pages all render only 'Connect wallet'
- —No OpenAPI spec or response schema provided; actual response format is unknown
- —The AML alerts endpoint is not listed on the provider's landing page among their advertised APIs, raising questions about its status
- —Compliance/AML data may be subject to regulatory requirements — verify data provenance and accuracy independently
