GoatCAD

Part search

Part search in the activity bar searches DigiKey and Mouser for real parts: prices, stock, datasheets and CAD model links. Each distributor needs a free API key, which takes a few minutes to get. Set them up in Settings ▸ Distributor APIs; Get a key from… opens the right page.

DigiKey

  1. Sign in on DigiKey’s developer portal and add a Production app. A Sandbox app uses a different server and will not work.
  2. Tick Product Information V4 in the product list. It starts with nothing ticked.
  3. Leave OAuth Callback empty. GoatCAD does not use it.
  4. Paste the app’s Client ID and Client Secret into GoatCAD and click Save key.

Mouser

  1. Sign in on Mouser’s API hub.
  2. Request a key for the Search API. Mouser sends it by email.
  3. Paste the key into GoatCAD and click Save key.

After setup

Each distributor shows a status: Connected, Not connected, Not checked or Not working. Test connection checks the key again.

Keys come with a small daily quota, around 1,000 requests. The settings page shows how much is used; it resets at midnight UTC. Filters apply when you click Apply filters rather than on every checkbox, so they do not spend requests one at a time.

Keys are encrypted with your system keyring. On a Linux system without one (no libsecret or KWallet), GoatCAD cannot encrypt a key and does not save it.
