# Check a hostname's DNS and certificate, and activate it

`POST https://studio.grid82.app/v1/suites/{suiteId}/domains/{hostname}/verify`

Check a hostname's status and advance it one step.

`pending`: look up the TXT record requested by `domains.attach`; when it appears, the hostname becomes `provisioning` while Cloudflare validates it and issues a certificate. This takes minutes and requires the CNAME to point here. `certificate` includes both states and any Cloudflare complaints. `active`: the hostname serves and starts routing to this suite. Safe to call repeatedly while DNS propagates.

Requires the `schema:write` scope. Operation `domains.verify`. MCP tool `domains_verify`. CLI: `grid82 domains verify` (`npx grid82`).
