Add and manage custom domains with separate sending and receiving readiness. Verify sender identity records and check MX routing independently.

Descripción General

By default, inboxes send from @agentsend.io. Adding your own domain lets you send from addresses like agent@yourdomain.com, improving deliverability and brand trust.

After adding a domain, AgentSend returns separate DNS records for sending and receiving. Once published, call the verify endpoint to refresh both statuses: sending checks SES sender verification and DKIM, while receiving checks whether the domain's MX points to AgentSend.

ℹ

All requests require an x-api-key header. Get your key from the dashboard.

El Objeto Domain

All domain endpoints return a Domain object (or an array of them).

💡

Publish all returned dnsRecords at your DNS registrar, then call POST /domains/{id}/verify to activate the domain.

GET /domains

List all domains on your account, including their current verification status.

Parameters

No query parameters.

DELETE /domains/{id}

Permanently delete a domain from your account. Inboxes using this domain will fall back to @agentsend.io addresses. This action is irreversible.

Path parameters

Parameter	Type	Description
`id` requerido	string (uuid)	The ID of the domain to delete.

curl

curl -X DELETE https://api.agentsend.io/domains/dom_01hxyz4k9s2n3p7q \

Response `204 No Content`

Returns an empty body on success.

⚠

Deleting a domain does not remove the DNS records from your registrar. You should clean those up manually after deletion.

POST /domains/{id}/verify

Trigger a fresh domain readiness check. AgentSend updates sender verification from SES and DKIM, then separately checks whether the domain's MX points to AgentSend for inbound mail.

Parameter	Type	Description
`id` requerido	string (uuid)	The ID of the domain to verify.

curl

curl -X POST https://api.agentsend.io/domains/dom_01hxyz4k9s2n3p7q/verify \
