Authentication

Two accepted header formats. Use one, do NOT mix:

x-scanbim-api-key: <your_user_key> — value is the user_key verbatim.
Authorization: Bearer sk_scanbim_<your_user_key> — value is the entire string including the sk_scanbim_ prefix; the D1 user_key column must match this full string.

Mixing formats auto-creates a fresh free-plan row for the alternate key (you'll silently get a new 50-credit account on each switch).

Get your user_key at scanbim.app/settings/billing.

Example

Terminal

curl -X POST https://mcp.scanbimlabs.io/unified/mcp \

  -H "content-type: application/json" \

  -H "x-scanbim-api-key: $SCANBIM_USER_KEY" \

  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"list_models","arguments":{}}}'
