Do I need a TikTok developer account?

No. There is no TikTok app, OAuth flow or app review. One InsightSocial API key works for this endpoint and every other platform, and your first 10 calls priced at 100 credits or less are free.

What does one call return?

One call returns the videos in the data object of the standard response envelope. Fields the platform did not provide are listed in unavailable, so a null there means unknown, not zero.

What happens if the account is private or nothing is found?

You get an error or an empty result, and it costs 0 credits. The API reads public TikTok data only, so private accounts and deleted content come back as not found rather than as partial data.

Can I call the TikTok Hashtags Popular API from Claude, ChatGPT or Cursor?

Yes. Add the hosted MCP server at https://api.insightsocial.app/mcp to your AI app and sign in. The assistant finds this endpoint by name, shows its price and calls it with your credits.

When to use it

Use it for seed-free trend collection by market. One board is three hashtags; pass industry=all for the overall board plus all 15 industry boards in one call.

Parameters

Query parameters for GET /v1/tiktok/hashtags/popular. Send your key in the x-api-key header.

Name	Required	Description
countryCode	No	Market to read the board for, as an ISO country code. One of the 27 markets TikTok publishes the board for. Defaults to US.
period	No	Window in days: 7, 30 or 90. Defaults to 7. Each window is a different board, not a longer list.
industry	No	Which board to read. Omit for the overall board (3 hashtags). Pass an industry slug for that industry's board (3 hashtags), or all for the overall board plus all 15 industry boards in one call.

Response fields

The same unified schema every platform returns, so code written for TikTok works on the other eight. A field the platform did not provide is null and listed in unavailable.

How much does the TikTok Hashtags Popular API cost?

Metered: 60–960 credits a call. The ceiling is reserved when the call starts and you are charged what it actually read.

Failed calls are free
A call that errors or finds nothing costs 0 credits.
Know the price first
Add dry_run=1 and the response quotes the call without making it. Nothing is charged.
One balance
API calls and Chrome extension exports share the same credits, on the free plan too.
