# MailBurner `mail.burner@1`

Generated at 2026-11-13 06:25:48 UTC from [`openvibe-contracts v0.419.0`](https://github.com/OpenVibers/OpenVibe.Contracts/tree/v0.419.0) and [`openvibe-sdk v0.161.0`](https://github.com/OpenVibers/OpenVibe.SDK/tree/v0.161.0).

- Version: 1.0.0
- Owner: mail
- Visibility: first-party
- Status: active
- Compatibility: backward
- Schema: [`https://openvibe.network/contracts/mail/burner.v1.json`](/docs/contracts/mail.burner.json)

A throwaway receive-only address on OpenVibe.Mail. It expires after ten minutes, an hour, a day or a week, or after the first message when first\_message\_only is set. When it expires its mail is deleted and the address bounces. A ten-minute burner may be made without an account (owner is null) and is then read with the one-time token the create call returns; the token is deliberately not part of this resource.

## Fields

| Field | Type | Required | Description | Constraints |
| --- | --- | --- | --- | --- |
| `id` | string | yes | The burner id. Opaque outside OpenVibe.Mail. | - `pattern ^bnr_[0-9A-HJKMNP-TV-Z]{26}$` |
| `owner` | string \| null | yes | The Network subject id of the person who made the burner, or null for a ten-minute burner made without an account. | - `pattern ^usr_[0-9A-HJKMNP-TV-Z]{26}$` |

| `expires_at` | string | yes | When the address stops resolving and its mail is due for deletion, ISO 8601 UTC. | - `format date-time` |
| `first_message_only` | boolean | yes | When true the burner accepts one message and then stops resolving. |  |
