Request an email domain
Records a pending claim on a domain for Vitable to verify. The claim grants nothing until then — it does not auto-join anyone and does not reserve the domain against another organization. Requesting a domain the organization already claims returns that claim unchanged rather than creating a second one.
Authentication
API Key or Access Token authentication using Bearer token in Authorization header. API keys use the vit_apk_ prefix, access tokens use the vit_at_ prefix.
Headers
Request
Bare email domain to claim, without the local part — acme.com, not jane@acme.com. Matching is exact, so mail.acme.com is a separate claim.
Response headers
Unix timestamp (seconds) when the rate limit window resets
