Give the TikTok Search Suggestions API a seed keyword and it returns the autocomplete phrases TikTok shows in its search bar as clean JSON — the actual phrases people search for. Each suggestion includes the search term, its rank (1 = top of the list), a ready-to-open search URL, the seed keyword it came from, and the country and language it was localized for. Use the country and language parameters to see what a specific market is searching (for example US in English, or DE in German). Great for TikTok keyword research, trending queries, and content planning. No TikTok login required. Billed per suggestion returned. Pass cache=true to serve from the 24h shared cache (0 credits on hit); default is always fresh.
