# Fact Check Tools API

## Getting Started

### The Google FactCheck ClaimReview Read/Write API

#### Typical use cases

- Adding ClaimReview markup, editing ClaimReview Markup, deleting ClaimReview Markup for a site's fact checking articles (URLs). To learn more about ClaimReview, visit the [Fact Check developer docs](https://developers.google.com/search/docs/data-types/factcheck).
Note: To add or make changes to a site's markup using this API, users must be [authorized](https://toolbox.google.com/factcheck/about#fcmt-creators) through Google Search Console. Any account that is listed as a restricted or full user of a site will be able to create markup for any articles of that site. The required steps are:

- Talk to your webmaster to find out if your site is already on Search Console. If not, follow [these steps](https://support.google.com/webmasters/answer/6332964).
- Ask your webmaster to add you as a user to the site, either as a restricted or full user ([instructions](https://support.google.com/webmasters/answer/2453966)).

You are responsible for informing your users that your API client will contribute data to
[dataCommons](https://datacommons.org/factcheck/download).
