TikTok User Profile Lookup

Use this endpoint when you need detailed profile data for a specific known TikTok user (by username, user ID, or URL) rather than discovering users via search. Prefer this over a search endpoint when you already know the exact identifier. It's ideal for enriching influencer databases, resolving numeric IDs from handles, or verifying account existence and follower stats.

• Username not found — returns 404 or empty result if the account doesn't exist or has been deleted
• Invalid input — error if more than one of username/user_id/url is provided, or none are provided
• Malformed URL — error if url parameter does not contain the tiktok.com/@username segment
• Private or banned account — may return limited or no profile data
• Rate limiting — too many requests may result in 429 responses
• User ID all zeros — rejected per schema validation
