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 accounts 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 Post Likers 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.

GET /v1/instagram/post/likers

Instagram Post Likers API

Q: How much does the Instagram Post Likers API cost?

50 credits per successful call. A call that errors or finds nothing costs 0 credits, and an answer from the shared cache costs 2. Pro's 10,000 monthly credits cover about 200 calls at 50 credits each. Add dry_run=1 to see the price of a call without making it.

Returns a sample of the accounts that liked a post, each with username, display name, avatar, and verification status, plus the full like count.

When to use it

Use it to see who liked a post, accepting that Instagram exposes only about the first 100 likers however many likes the post has.

Parameters

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

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.

username	string \| null
display_name	string \| null
avatar_url	string \| null

followers	integer \| null	A count. null when the platform does not expose it; 0 only when it is really zero.

posts_count	integer \| null	A count. null when the platform does not expose it; 0 only when it is really zero.
likes_count	integer \| null	A count. null when the platform does not expose it; 0 only when it is really zero.

Every field, error and example is in the Instagram Post Likers API reference.
