How this service works
RelayShield Landing Site
Output
Returns a JSON object with a found boolean, the queried email, a list of data sources, arrays of correlated phone numbers and domains, and a count of total correlated identifiers. If the email is not found, found is false and all arrays are empty.
Example use cases
Fraud investigation email enrichment
“I need to investigate this suspicious account — can you look up user@suspiciousdomain.com in the identity graph and tell me what phone numbers, domains, or other identifiers are correlated with it?”
Sales lead contact enrichment
“I have a lead's email address, contact@prospectcompany.com — can you pull the identity graph data to see what phone numbers and associated domains are linked to them?”
Onboarding identity verification check
“Before we approve this new user, can you check newuser@gmail.com against the identity graph to see if it shows up in any data sources and what identifiers are correlated with it?”
