> Where to issue an Anthropic API key and connect it to Nora.

Anthropic integrations let your agents call Claude (Opus, Sonnet, Haiku) for text generation and analysis. Nora authenticates with the standard `x-api-key` header.

## Where to apply for credentials

  <Step title="Create a key">
    Settings → API keys → **Create Key**. Give it a descriptive name (e.g. "nora-prod-agent").
  </Step>

  </Step>
</Steps>

## Connect in Nora

Paste the API key. Optionally set **Default Model** to one of:

* `claude-opus-4-7` — most capable
* `claude-sonnet-4-6` — balanced cost / quality
* `claude-haiku-4-5` — fastest, cheapest

Nora calls `GET https://api.anthropic.com/v1/models` to validate.
