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.

How do I get every result, not just the first page?

This endpoint pages. Each response carries pagination.next_cursor and pagination.has_more. Send next_cursor back unchanged as the cursor parameter and stop when has_more is false. Every page is a separate call and is charged as one.

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 Video Comments 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 to read a video's comment section; to expand one thread, take a comment's id and call video/comment/replies.

Parameters

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

Name	Required	Description
url	Yes	Full URL of the TikTok video to fetch comments for
cursor	No	Cursor to get more comments. Get 'cursor' from previous response.
trim	No	Accepted for compatibility; the response is already the canonical shape, so this flag has no effect.
sort	No	Optional. Without it, comments come in TikTok's own order (a relevance ranking, not newest first). recent returns them newest first by published_at; top returns them by like count. TikTok has no newest-first order of its own, so recent sorts the comments that were read: set scan_pages to read more of the thread.
scan_pages	No	Optional, 1 to 3, default 1. Reads that many pages, drops comments repeated across pages, and returns them all in the sort order (TikTok's own order when sort is absent).

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.

Field	Type	Notes
id	string	An identifier, always a string. Never parse it as a number: several platforms use ids above 2^53.
url	string \| null
parent_id	string \| null	An identifier, always a string. Never parse it as a number: several platforms use ids above 2^53.
post_id	string \| null	An identifier, always a string. Never parse it as a number: several platforms use ids above 2^53.
text	string \| null
author.id	string \| null
author.username	string \| null
author.display_name	string \| null
author.avatar_url	string \| null
author.verified	boolean \| null
engagement.likes	integer \| null	A count. null when the platform does not expose it; 0 only when it is really zero.
engagement.replies	integer \| null	A count. null when the platform does not expose it; 0 only when it is really zero.
flags.pinned	boolean \| null
flags.deleted	boolean
published_at	string \| null	ISO-8601 timestamp in UTC, ending in Z.
language	string \| null	The content's language as the platform states it, e.g. en, pt-BR. Detected languages come later (§7.1).
replies	array \| null
ext	object \| null	Platform-specific fields, snake_case.

Every field, error and example is in the TikTok Video Comments API reference.

How much does the TikTok Video Comments API cost?

Metered: 10–30 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.
