# API Scorecard

Reunite's scorecard feature enables you to add and create sets of rules and test your API description files against them.
Using these rules you can maintain quality across your existing APIs and ensure that newly-added or updated APIs match your criteria.
An API scorecard can include multiple sets of rules, corresponding to different quality levels.

When new quality criteria arise, you can add more levels to reflect the evolving standards.
There is no limit to the number of levels you can have.

You can set up a baseline ruleset and prevent APIs that do not meet this standard from publishing to your production project.

## Scorecard information

After you define the rules for the API scorecard, reports display in Reunite and on your production project.
If you have versioned APIs, each version displays as a separate row.
Reports show if an API description file complies with the applied rulesets.

### Scorecard reports in the Lint CI job

You can view scorecard reports on Reunite's **Deploys** page.
Choose a preview or production deploy and click it to open its status page.
Under **Summary**, click **Lint** to display the report.

### Scorecard status in API registry

The API description details on the **API Registry** page contains a summarized version of the scorecard reports.
You can find this information by clicking an API.
The summarized scorecard report is on the **Details** tab.

## Scorecard labels

After you define scorecard levels and commit the changes, labels representing the scorecard levels display next to the names of your API descriptions in Reunite and on your published project.
