Use cases
Down-rank brand-new or high-risk domains during registration and affiliate onboarding.
Add domain reputation context to KYC and payment risk decisions.
Prioritize complainants and spoof reports with a single score snapshot.
Attach domain risk level to CRM leads before sales outreach.
Integration
Subscribe to a Domain Reputation plan and copy your dr_sec_ secret key from the client area.
Call /v1/domainrep/lookup/{domain} or ?domain=.
Allow low, challenge medium, and block or escalate high—using signals for audit trails.
Example
Every response includes a request_id for support correlation.
Rate limit and quota headers are returned on authenticated routes so you can backoff gracefully.
Authenticated with your Syndaq secret key over HTTPS. Score is risk-oriented (higher = more risky). Individual signals may soft-fail; a score is still returned when possible.
