Check legal-entity name availability
Checks for an existing registered name using the same case-insensitive exact-name and entity-option rule as incorporation. Send the name without its legal extension and an optionId (for example llc). Accepts a Standard Key or an Agent Key with agent:registry.search. This read-only check does not reserve a name or guarantee approval; drafts are not reservations, and the check is repeated during incorporation.
Account deactivation revokes personal API keys, including Agent Keys, and OAuth authorizations. Account reactivation requires new API keys, including new Agent Keys, and consent; previously issued credentials remain invalid.
Personal standard API key. Send it as Authorization: Bearer sk-... and never delegate it.
