TL;DR
Get the autocomplete terms TikTok suggests in its search bar for a keyword — the real phrases people search, ranked, so you can find trending queries and long-tail keyword ideas. The TikTok Search Suggestions API (TikTok) is a single authenticated GET request to /v1/tiktok/search-suggestions that responds with clean JSON and costs 2 credits. Pass cache=true for a free 24h cache hit; default is always fresh. Start with 100 free credits — no credit card.

What is the TikTok Search Suggestions API?

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.

What you get

  • The autocomplete terms TikTok suggests for your keyword
  • Each suggestion with its rank — the order it appears in the search bar
  • A ready-to-open searchUrl that runs that exact search on TikTok
  • The seed keyword plus the region and language it was localized for
  • Localize by country + language to see what a specific market searches
