Do I need a Instagram developer account?

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

Can I call the Instagram Comment 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 when you already know which comment you want, so you do not have to page through post/comments to find it again.

Parameters

Query parameters for GET /v1/instagram/comment. Send your key in the x-api-key header.

Name	Required	Description
comment_url	One of comment_url, post_url	An Instagram comment permalink: https://www.instagram.com/p/{shortcode}/c/{commentId}/ (or a reply permalink .../c/{parent}/r/{reply}/, best-effort). Mutually exclusive with post_url+comment_id.
post_url	One of post_url, comment_url	The post URL (a /p/, /reel/, /reels/, or /tv/ link). Combine with comment_id, or with author_username/text_contains for a search.
comment_id	No	The target comment's numeric id (pk). Requires post_url.
author_username	No	Return up to max comments authored by this username (no comment id needed). Mutually exclusive with text_contains and any comment id.
text_contains	No	Return up to max comments whose text contains this snippet (case-insensitive). Mutually exclusive with author_username and any comment id.
deep_scan	No	Widen the scan budget for deeply-buried comments (raises the per-chain page ceiling and deadline).
position_hint	No	Opaque token from a prior lookup's lookup.position_hint. Passing it back replays just the last-known sort chain first, making a re-check of an already-found comment cheap.
max	No	For author_username/text_contains search: max matches to return (1-20, default 5).

Response fields

The same unified schema every platform returns, so code written for Instagram 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 Instagram Comment API reference.

How much does the Instagram Comment API cost?

Metered: 50–150 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.
