## When to prefer this

Use this endpoint when you have a person's full name and their employer's domain and need to find their professional email address. Prefer this over the LinkedIn finder when you don't have a LinkedIn URL, and over the Author Finder when the person is not a blog author. Ideal for B2B sales prospecting, recruiting outreach, or journalist contact lookup.

## Known failure modes

- No email found if the person does not appear in Tomba's database for that domain
- Invalid domain format returns a 400 error
- Missing required parameters (first name, last name, or domain) returns a validation error
- Low confidence result when name is common or domain has many employees
- Rate limit exceeded returns a 429 error
- Insufficient USDC balance returns a payment error
