/people/unclaimed

The /people/unclaimed endpoint lists leads which have not been claimed yet, and can be claimed by the user whose API key you're using. Unclaimed leads will be assigned to a fallback agent after a short amount of time (default is 15 minutes), so this list is usually empty.

If you want to see both regular and unclaimed leads, use /people instead and specify includeUnclaimed=true as a query argument.
