Look up a public Threads profile (beta)
Beta. Resolves a public Threads profile by exact username and returns its public metrics. Requires the threads_profile_discovery Threads permission, which is pending Meta App Review, so calls may return an upstream authorization error for accounts outside the app’s tester roster until that permission is granted. Matching is exact, with no fuzzy or prefix search. Only profiles with 100 or more followers are discoverable, anything else returns 404. The upstream budget is 1000 lookups per user per rolling 24 hours.
