Technical details
Endpoint
GEThttps://x402.orthogonal.com/tomba/v1/email-formatWhen to prefer
Use this endpoint when you need to discover the email naming convention for a domain before constructing or guessing an individual's email address. Prefer this over a full email finder when you don't yet know the person's name or want to understand the pattern for bulk outreach. It's especially useful as a precursor step to the find-email endpoint.
Side effects
- Domain not found or no email pattern data available — returns empty or null result
- Invalid domain format causes a 400 bad request error
- Unknown or very small company domains may have no indexed email pattern data
- Rate limiting or payment failure results in 402 or 429 response
