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/55`. It is part of a broader platform offering dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services. All endpoints use the x402 payment protocol, settling in USDC on the Base network.
The specific endpoint probed (`/api/v1/aml/alerts/55`) returns a 402 challenge requesting up to $0.02 per request (20,000 base units of USDC with 6 decimals). The platform advertises uniform $0.02/request pricing across all its APIs with no API keys, no rate limits, and no minimum commitments. Payment is made inline via the X-PAYMENT header using the x402 exact scheme.
Documentation is extremely sparse — the docs, pricing, API, 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 the AML alerts endpoint actually returns or what parameters it accepts. The endpoint path includes a numeric ID (55), suggesting it retrieves a specific alert record, but this is inference only. The lack of documentation makes it difficult to assess the actual utility or data quality of this endpoint.

Quality
The endpoint is live and returns a valid x402 challenge, but documentation is essentially nonexistent — all doc pages show only 'Connect wallet'. There is no OpenAPI schema, no request/response examples, and no description of what the AML alerts endpoint returns or accepts. The listing is effectively a stub.
Warnings
- —No API documentation available — all doc pages render only 'Connect wallet'
- —No OpenAPI or request/response schema provided
- —The AML alerts endpoint path and functionality are entirely undocumented; actual data content is unknown
- —This endpoint appears to serve compliance/regulated data (AML) but provides no information about data sources, accuracy, or regulatory standing
- —The endpoint path includes a hardcoded ID (55), and it is unclear how to discover or query other alert IDs
