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 row carries only what varies — the search term, its rank (1 = top of the list), and a ready-to-open search URL. The envelope echoes the market you requested once: query, country (named to match the country parameter), and language. 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. Flat 2 credits per call, no matter how many suggestions return. Pass cache=true to serve from the 24h shared cache (0 credits on hit); default is always fresh.
