Get API key

A step-by-step guide on how to get an API key to use OpenRouter models.

1. Sign up for an account

   First, visit the OpenRouter↗ website and create an account. Click the Sign in button in the top right corner and then Sign up to create your account.

2. Navigate to the API Keys Section

   Once signed in, go to API Keys↗ section.

3. Generate New API Key

   Click the Create Key button and give it a descriptive name, and optionally, a credit limit.

   Note that you won't be able to view the key again once you leave this page, so make sure to save it somewhere safe.

   It's important to remember that your API key is like a password, so treat it as confidential information. Only you should know it and if it falls into the wrong hands, others may be able to use it to access Anthropic services using your account.

4. Enter your API key into Kerlig

   Go to Settings, Integrations tab, then select OpenRouter.
