Do I need a YouTube developer account?

No. There is no YouTube 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 YouTube data only, so private accounts and deleted content come back as not found rather than as partial data.

Can I call the YouTube Search Hashtag 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 hashtag feed rather than a keyword query; set type to shorts to limit the results to Shorts.

Parameters

Query parameters for GET /v1/youtube/search/hashtag. Send your key in the x-api-key header.

Name	Required	Description
hashtag	Yes	Hashtag to search for without the # symbol
type	No	Search for all types of content or only shorts
include	No	Set to engagement, channel, or both (engagement,channel) to fill more of every row in this one call. engagement fills post.engagement.views, .likes and .comments, post.content.duration_seconds, author.id and post.author.display_name where the row lacks them, and replaces a date derived from a label such as "4 months ago" with the exact publish time (removing post.ext.published_precision). channel puts the channel's subscriber count on post.ext.author_followers (YouTube's own figure, which it rounds to three significant figures above 1,000) and fills the channel's post.author.display_name, .avatar_url and .username where missing. Send both to cover rows that arrive without a channel id: the video join supplies it and the channel join then uses it. Each join adds 0.2 to 0.7 seconds on a fresh page (one lookup per 50 ids, never more than 8 seconds).
exact_dates	No	Exact publish dates are on by default and free. Set to false to skip the lookup: those rows then carry the supplier's estimate (a day-granular or coarser label truncated to midnight UTC), marked by post.ext.published_precision and post.ext.published_label.
min_views	No	Keep only rows with at least this many views (post.engagement.views). A row whose view count is unknown is discarded, so every returned row meets the floor.
max_age_days	No	Keep only rows published within this many days (post.published_at), 1 to 3650. A row with no date is discarded.
sort_rows	No	views: return the kept rows ordered by view count, highest first, across every page walked. Rows without a view count go last.
max_pages	No	1 to 5 (default 1). Walk up to this many pages in one call and return the rows from all of them (after any filter). Each page walked is billed as one call to this endpoint; the whole walk counts once against your rate limit.
cursor	No	The pagination.next_cursor from the previous page, sent back unchanged. Omit it for the first page.

Response fields

The same unified schema every platform returns, so code written for YouTube 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
kind	string \| null	The format of the post. Format words only, never a platform name. short = short-form vertical video (a reel, a TikTok, a YouTube Short).
content.text	string \| null
content.media_urls	array \| null
content.thumbnail_url	string \| null
content.duration_seconds	number \| null
author.id	string \| null
author.username	string \| null
author.display_name	string \| null
author.avatar_url	string \| null
author.verified	boolean \| null
engagement.views	integer \| null	A count. null when the platform does not expose it; 0 only when it is really zero.
engagement.likes	integer \| null	A count. null when the platform does not expose it; 0 only when it is really zero.
engagement.comments	integer \| null	A count. null when the platform does not expose it; 0 only when it is really zero.
engagement.shares	integer \| null	A count. null when the platform does not expose it; 0 only when it is really zero.
engagement.saves	integer \| null	A count. null when the platform does not expose it; 0 only when it is really zero.
flags.nsfw	boolean \| null
flags.spoiler	boolean \| null
flags.pinned	boolean \| null
flags.deleted	boolean
flags.likes_hidden	boolean \| null
flags.comments_hidden	boolean \| null
flags.shares_hidden	boolean \| null
flags.views_hidden	boolean \| null
flags.saves_hidden	boolean \| null
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).
ext	object \| null	Platform-specific fields, snake_case.

Every field, error and example is in the YouTube Search Hashtag API reference.

How much does the YouTube Search Hashtag API cost?

Metered: 10–110 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.
