# Estimate a domain renewal

> <Tip>
  **New.** This endpoint shipped recently. If anything about it is unclear or could work better for you, tell us in the [developer Slack](/slack).
</Tip>

<small>_Requires the `channels:read` scope (or a broader one that includes it)._</small>

Previews what renewing one purchased domain would charge, at the provider's current price. Nothing is charged and nothing is renewed. No request body.

It applies the same checks as POST /v3/email-accounts/procurement/domains/{domainId}/renew, so an estimate that succeeds means the renewal can be requested now. The total can still change by the time the renewal is charged, since the provider's price is taken again then.

                              * `resource` is the camelCased domain — e.g.
                              `sequence`,
                                `contact`, `inboxThread`, `blacklistDomainRule`.
                              * `variant` is the camelCased specific failure
                              mode — e.g.
                                `notFound`, `forbidden`, `duplicateName`, `globalRuleReadOnly`.

                              Use `code` for programmatic error handling; use
                              `detail` for

                              user-facing messages. Slugs are stable across

                              reorderings and never change meaning under a given
