The Crystal API analyzes text or personality assessment data. It cannot create personality assessments with only an email address or URL.
There are several ways you can use the Crystal API:
- Embed the Crystal Chrome Extension sidebar in your web app (details)
- Analyze text samples, such as a resume or bio (details)
- Display personality assessments results in your app (details)
However, the Crystal API does NOT provide analysis from just an email address or LinkedIn profile URL. To identify someone's personality from a LinkedIn profile, you would need to use the Chrome Extension on that profile and analyze the text loaded on the page.
