How this service works
Create Domain
Output
Returns a Domain object containing a domain_id, verification status (e.g. NOT_STARTED, PENDING, VERIFIED), a list of required DNS records (TXT, CNAME, MX) with their names, values, and current validation status, plus timestamps for creation and last update. Also includes client_id and pod_id for internal tracking.
Example use cases
Example prompt
“Set up mycompany.com as an email domain in AgentMail with bounce and complaint feedback notifications enabled, so I can create agent inboxes under that domain.”
Technical details
Endpoint
POSThttps://mpp.api.agentmail.to/v0/domains?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to register a custom domain within AgentMail so that AI agents can send and receive emails using addresses on that domain. This is the first step before creating inboxes under a custom domain. It is the right choice when the user owns the domain and is prepared to add DNS records for verification.
Side effects
- Domain already registered — returns conflict error
- Invalid domain name format — validation error on 'domain' field
- Missing required fields (domain or feedback_enabled) — 400 Bad Request
- Unauthorized — missing or invalid Bearer token returns 401
- Domain name contains unsupported characters or TLD — validation failure
