How this service works
Screen a blockchain address for fraud reports and risk score. Legacy alias — prefer GET /api/v1/screen/:address for new integrations.
Output
Returns a verdict of 'caution' if the address has community fraud reports or is OFAC-sanctioned, or 'clean' if no issues are found, along with a risk score and any associated fraud report metadata from the C3 database.
Example use cases
Example prompt
“Can you screen the blockchain address 0x3f5CE5FBFe3E9af3971dD833D26bA9b5C936f0bE against the C3 community fraud database and tell me if it's flagged as caution or clean?”
Technical details
Endpoint
GEThttps://blockint.ai/api/v1/c3-reports/check/:addressWhen to prefer
Use this endpoint when you need a quick fraud and sanctions check on a specific blockchain address and are working with existing integrations that reference the legacy c3-reports path. For new integrations, prefer GET /api/v1/screen/:address. Best suited for pre-transaction due diligence, compliance workflows, or scam detection pipelines.
Side effects
- Invalid or malformed blockchain address returns an error
- Address not found in database still returns a clean verdict (not an error)
- Rate limiting or payment failure returns 402 or 429
- Network timeout on slow blockchain lookups
- Legacy endpoint may be deprecated in future — prefer /api/v1/screen/:address
