## Flagship API reference now available

The **[Flagship API reference](https://developers.cloudflare.com/api/resources/flagship/)** is now available. You can use the Cloudflare API to create and update apps, and to create, update, delete, and list feature flags without using the dashboard.

For example, create a new boolean flag with the API:

```bash
curl https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/flagship/apps/$APP_ID/flags \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
  -d '{
    "key": "new-checkout",
    "enabled": true,
    "default_variation": "off",
    "variations": {
      "off": false,
      "on": true
    },
    "rules": []
  }'
```

To create an API token, go to [Account API Tokens ↗︎](https://dash.cloudflare.com/?to=/:account/api-tokens) in the Cloudflare dashboard and search for Flagship.

The API reference includes endpoints for Flagship apps, flags, changelog entries, and flag evaluation. Agents can also use the [Flagship reference in the Cloudflare skill ↗︎](https://github.com/cloudflare/skills/tree/main/skills/cloudflare/references/flagship) to create and manage Flagship resources.

Refer to the [Flagship documentation](https://developers.cloudflare.com/flagship/) to learn more about evaluating feature flags from your applications.
