Connect it in a minute

The connect flow is agent-driven: Even opens the key page in its own browser and collects the key through a secure native field. It never passes through the chat.

Paste the prompt below into any agent running inside Even, or click Connect in Even's catalog.
Go to Buttondown > Settings > API.
Copy the API key shown there.
Paste the key into Even's secure field. Even verifies it and your agents are live.

The connect prompt Connect Buttondown to Even: call connect_begin("buttondown") on the even-connect MCP and walk me through it.
