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/50` is not listed on the provider's public landing page, which primarily advertises Data & Analytics, AI/ML, Finance/Web3, and Infrastructure APIs — all priced at $0.02 per request. The AML alerts endpoint follows the same x402 payment pattern but with a price of $0.02 per call (20,000 base units of USDC on Base, which has 6 decimals).
The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with the "exact" payment scheme. No API keys or rate limits are advertised — access is gated entirely by the x402 payment header. The provider's site claims instant access with no minimums or commitments.
Documentation 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 description of what the AML alerts endpoint actually returns. The endpoint path suggests it retrieves alert data (possibly alert ID 50 or a batch of 50 alerts), but this is speculative. Without documentation or sample responses, integrators will need to experiment to understand the data format and semantics.

Quality
The endpoint is live (returns a valid 402 x402 challenge), but there is virtually no documentation — no OpenAPI schema, no request/response examples, and the AML alerts endpoint is not even listed on the provider's landing page. The docs pages are empty. The actual data returned is unknown.
