Check whether a host can be connected by the API-key owner inside Biqli.
GET
Check domain availability
Check whether a host is available to connect inside Biqli. This is not a
registrar lookup and does not tell you whether the domain can be purchased.
Requires Custom domains: Write (
A host already owned by the API-key user remains available for attachment to
this workspace:
If the host is already attached to this workspace,
custom_domains.create) and a plan that
includes custom domains.
Responses
A host not claimed in Biqli:reason is
already_connected. This remains safe when another workspace member originally
created the shared workspace domain.
A claim owned by another Biqli account returns 200 OK with
available: false, reason: domain_taken, and a null domain_id. It does not
reveal who owns the domain. Invalid, unsafe, blacklisted, or application hosts
return 422 validation_error.
Because availability can change between checking and creating, always handle
409 domain_taken from Create a domain.
Shared API behavior
Authentication is workspace-scoped; see Authentication. Errors use the standard envelope and request IDs described in Errors, and requests are subject to Rate limits.Authorizations
A workspace API key beginning with biqli_.
