Block Agent Signup

Block and disable an agent-provisioned API key.

Blocks a pending agent signup, immediately disabling the API key and banning the sandboxed account. Use this if the agent created a key without authorization. No authentication required — the verification token acts as proof.

What Happens on Block

• The agent’s API key is deleted.
• The sandboxed team is banned.
• The sponsor record is marked as "blocked", preventing future agent signups for that email.
• Any further API requests using the blocked key will return 403.
