Technical details
Endpoint
GEThttps://blockint.ai/api/v1/domains/check/:domainWhen to prefer
Use this endpoint when you need to quickly assess whether a specific domain is associated with phishing, fraud, or scams according to community-sourced C3 reports. Prefer this over the address screener when the suspicious entity is a URL/domain rather than a blockchain wallet address. Ideal for pre-click safety checks, anti-phishing workflows, or validating URLs encountered in crypto/Web3 contexts.
Side effects
- Domain not found in database returns clean/no-match result
- Invalid domain format (e.g. includes protocol like https://) causes a 400 error
- Payment not included or rejected causes a 402 Payment Required response
- Rate limiting or service unavailability returns 5xx error
- Domain with no reports returns empty report list but valid risk score
