Output
A list of web sources — URLs and associated page metadata — where the queried email address has been found or indexed on the web, helping verify email provenance and online presence.
Example use cases
Verify lead email legitimacy
“I've got a lead with the email sarah.jones@techstartup.io — can you find which websites this email has been indexed on so I can verify it's a real, active address?”
OSINT email footprint research
“I'm researching the online footprint of contact@shadowfirm.net — can you find all the web sources where this email address has been discovered or listed?”
Sales prospecting email validation
“Before I reach out, can you check where the email m.rodriguez@bigcorp.com has shown up online so I know it's legitimate and sourced from real pages?”
Technical details
Endpoint
GEThttps://x402.orthogonal.com/tomba/v1/email-sourcesWhen to prefer
Use this endpoint when you need to verify the online provenance of an email address, enrich a lead profile by finding where the email was publicly listed, or conduct OSINT research on an email's web presence. Prefer this over general web scrapers when you specifically need structured source data tied to an email address rather than broad web content.
Side effects
- Email not found in any indexed sources — returns empty results
- Invalid or malformed email address input — may return an error or empty response
- Email exists but originates from private/unindexed pages — sources may be incomplete
- Rate limiting or payment verification failure — request rejected
- Newly registered or obscure email addresses may have no indexed sources yet
