Connect
The fastest route is Claude: connect with one click, sign in by email, no API key at all. With the first connection, 50 credits (≈ 50 companies, valid for 90 days) are active immediately.
In Claude: open Firmenbuch in the connector directory and choose "Connect". Alternatively, enter the server URL directly (Settings → Connectors):
On the first connection you receive an email with a 6-digit code. Type it into the open window and you are done: the account is created and the 50 free credits are active.
Test it in the chat: "Are you connected to Agentic-Firmenbuch? What can you query?" If the agent names the Firmenbuch tools, everything is ready.
Automation & your own tools
Cursor, VS Code and Claude Code connect just like Claude via an email code, no key at all. An API key is only needed where no browser sign-in is possible: CI/CD pipelines, servers, your own programs, or several machines sharing one access.

Create and manage keys in the web app: named, individually revocable at any time, shown only once for security. Several keys per account, for example one per machine; a new key never affects existing connections.
Sign in there (email is enough), then create keys under Account & credits → API keys.
You can see your balance in the web app or directly in your AI tool (“How many credits do I have?”). With an API key also here:
When the credits run out
Credit packs are available immediately after payment, valid for 12 months, with a money-back guarantee for unused credits. Alternatively Pro with 1,500 credits per month.
