Screen a crypto address using TRM Labs BLOCKINT API before processing a withdrawal

Steps

1. Authenticate: include your TRM API key as Authorization: Basic YOUR_API_KEY (base64-encoded) or as an Authorization: Bearer token per TRM's current auth scheme — verify with TRM documentation as format may vary by account type
2. Screen the destination address: POST https://api.trmlabs.com/public/v2/screening/addresses with body [{"address": "<address>", "chain": "ethereum"}]; TRM returns results in under 400ms
3. Parse the response: check riskScore (0-100), riskLevel (LOW/MEDIUM/HIGH/SEVERE), and riskIndicators array for specific exposure categories (e.g. sanctions, darknet_market, stolen_funds)
4. Apply your risk policy: block if riskLevel is HIGH or SEVERE; queue for manual review if riskLevel is MEDIUM; allow if LOW — document the riskScore and indicators for the compliance record
5. For transaction monitoring, POST /public/v2/transaction-monitoring/transactions with the transaction hash and chain to initiate ongoing monitoring of the transfer once broadcast
6. Retrieve monitoring alerts: GET /public/v2/transaction-monitoring/alerts with filters status=OPEN and minRiskScore=<threshold> to support compliance triage queues
