# View API

View API is a read-only API to deliver content to web and mobile properties using Arc XP as a headless CMS solution. The API is available through a globally distributed CDN to accelerate content delivery and reduce latency.

## Authentication

View API works with public-facing keys. These are different than your Arc Tokens that are used for the administration APIs. You can find documentation on how to create your API token: [Provisioning tokens through Delivery API](https://dev.arcxp.com/platform-tools/developer-docs/provisioning-tokens-through-delivery-api). Once you have an API key, you can use it to authenticate with the View API by sending it in the `X-API-Key` header on your requests.

> Note: View API provisioning is not available for secondary organizations.

## Preview Content

View API should not be used to retrieve preview content. Instead, use the [Preview API](https://dev.arcxp.com/api/content-administration/preview-api).
