Create an OpenRouter API Key

Blazebar needs an API key to talk to models via OpenRouter. This takes about 2 minutes. You'll need an OpenRouter account.

Open the API Keys page

Go to openrouter.ai/settings/keys and log in. Click the Create button in the top-right corner.

openrouter.ai/settings/keys

API Keys Create

Manage your keys to access all models

	Key	Expires	Last Used	Usage	Limit
	My Key sk-or-v1-489...57d	Never	11 days ago	$0.839	$10 MONTH

Give your key a name (e.g. Blazebar). Leave Credit limit blank for unlimited, keep Expiration set to No expiration, and click Create.

Create

Your key is shown only once. Click Copy and save it somewhere safe. It starts with sk-or-v1-...

openrouter.ai/settings/keys

Copy this key now — you won't be able to see it again.

sk-or-v1-xxxxxxxxxxxxxxxxxxxxxxxxxxxx...xxxx Copy

Done

Open Blazebar settings (click the menu bar icon → Settings), select OpenRouter as your provider, and paste your API key.

Tip: Blazebar stores your key securely in the macOS Keychain and sends it only to OpenRouter — never to Blazebar's servers.

OpenRouter uses prepaid credits. Go to Credits in the sidebar and click Add Credits. Load at least $5 to get started.

You're all set.
