Do I need a Twitter/X developer account?

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

Can I call the Twitter/X Tweet Replies 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/twitter/tweet/replies

Twitter/X Tweet Replies API

Q: How much does the Twitter/X Tweet Replies API cost?

10 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 1,000 calls at 10 credits each. Add dry_run=1 to see the price of a call without making it.

Returns the replies to a tweet, each with the reply text, author info, like and reply counts, and creation time. The tweet itself is not in the list.

When to use it

Use it with a tweet URL to read the conversation under it; the cursor walks deeper threads, and a tweet with no replies returns an empty list.

Parameters

Query parameters for GET /v1/twitter/tweet/replies. Send your key in the x-api-key header.

Name	Required	Description
url	Yes	Full URL of the tweet to fetch replies for
cursor	No	Cursor from the previous response's pagination.next_cursor to fetch more replies

Response fields

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