Works where you work

claude.ai as a custom connector, ChatGPT in developer mode, Claude Code with one command, or any other MCP client.

Sign in, don't paste keys

Access runs through your Treffer account and can be revoked there anytime. Clients without a sign-in flow can send an API key instead.

Safe to hand to an agent

A lookup that finds nothing costs nothing, every call is logged to your account, and the same rate limits apply as on the API.

The same German data

MCP, API and dashboard run the same lookups on one account and one credit balance. Specialist depth, whichever door you use.

Pay for results, not attempts

A found email or profile costs credits. A miss costs nothing. Plans start small and scale with your volume.
