# Expertises

## List expertises

Public endpoint to list all available expertises supported by TextMaster.

Expertises allow clients to create projects that will only be available to authors with expert skills in a given area. Author expertises are validated by TextMaster's community managers in order to allow verified experts to work on sensible projects.

Expertises are scoped by activity, meaning that the copywriting activity has a different expertise set than the translation and proofreading activities.
