- Search contacts by name to retrieve email addresses for composing mail. Returns matching contacts with names and emails.MIT
- Remove a domain from Resend by its ID, permanently stopping all email sending and receiving for that domain.MIT
- Check service connectivity and latency for AI conversation components to verify operational status before sending messages.
- Provision a phone number for receiving SMS, sending messages, or making voice calls. Specify a phone number or area code to get an E.164 number for 2FA or outbound calls. Save the returned number for later use.MIT
