When page.has_more is true, send page.cursor back as cursor for the next page; each page costs 2 credits and a cursor works for 30 minutes. - A call that runs and finds nothing is a successful call: status is "empty", items is empty, and it costs 2 credits. - On this call X cannot tell a post that does not exist from one with no data: both come back as empty, and both are charged. - 5 calls per second per key, 20 after a purchase; going over is not charged. [Rate limits](https://socialtoai.com/docs/credits-and-billing.md#rate-limits) - A failed call costs 0 credits and is never retried on its own. [Error codes](https://socialtoai.com/docs/api/errors.md) - Interface last tested: 2026-11-01. Each call reads from the platform, and `fetched_at` in the answer is when it was read. The same request sent again with the same key within 5 minutes is a replay (`replayed: true`): 0 credits, and the answer as first read. ## Once connected over MCP, these questions use the X (Twitter) post retweeters API - Get a page of the accounts that retweeted an X post, by the post's ID: 2108198226532708497. → `call {"op":"x.retweeters","id":"2108198226532708497"}`, 2 credits - Search X for posts about "weather forecast", then for the first 3: get a page of the accounts that retweeted an X post, by the post's ID. → `search {"platform":"x","query":"weather forecast"}`, `call {"op":"x.retweeters","id":""}` × 3, 8 credits ## Give this to your AI ``` Use the SocialToAI MCP server (https://mcp.socialtoai.com/mcp) for this: Get a page of the accounts that retweeted an X post, by the post's ID: 2108198226532708497.

Before you start, work out how many credits it will take in all and ask me; call it only after I agree. What usually comes next, with the ref or username it returns: user_profile (User Profile), user_posts (User Posts). If SocialToAI is not connected yet, tell me how to connect it; never ask me to paste a key into the chat. Answer with a link to every item you used, and tell me how many credits it cost. ``` ## More on X | Interface | What it does | Price key | Credits | | --- | --- | --- | --- | | [X (Twitter) thread context API](https://socialtoai.com/x-thread-api.md) | Get the posts of an X thread by the ID of any post in it. | `x.thread` | 9 | | [X (Twitter) post quotes API](https://socialtoai.com/x-quotes-api.md) | Get a page of the X posts that quote a post, newest first or most popular first. | `x.quotes` | 4 | | [X (Twitter) Search API](https://socialtoai.com/x-search-api.md) | Find posts by keyword: text, author, likes, comment count, views and publish time. | `x.search` | 2 | | [X (Twitter) article detail API](https://socialtoai.com/x-article-api.md) | Get the long-form article attached to an X post by the post's ID. | `x.article` | 2 | | [X (Twitter) user followers API](https://socialtoai.com/x-followers-api.md) | Get a page of the accounts following an X user, up to 200 a page, newest followers first. | `x.followers` | 12 | | [X (Twitter) user following API](https://socialtoai.com/x-following-api.md) | Get a page of the accounts an X user follows, up to 200 a page. | `x.following` | 12 | | [X (Twitter) user mentions API](https://socialtoai.com/x-mentions-api.md) | Get a page of the posts that mention an X user, newest first. | `x.mentions` | 4 | | [X (Twitter) Trending API](https://socialtoai.com/x-trending-api.md) | What is trending now: title, rank and heat. | `x.trending` | 6 | | [X (Twitter) Detail API](https://socialtoai.com/x-detail-api.md) | One post by ID or link: text, author, likes, comment count, views and publish time. | `x.detail` | 1 | | [X (Twitter) Comments API](https://socialtoai.com/x-comments-api.md) | The comments under one post: text, likes, reply count and time. | `x.comments` | 2 | ## Read next - [X official API: access, prices and limits](https://socialtoai.com/does-x-have-an-api.md): What its own API allows, who can use it and what it costs, with sources. - [How to let AI read X when the official API is too expensive](https://socialtoai.com/how-to/read-x-when-the-official-api-is-too-expensive.md): X's official prices, with sources, and reading X per call instead - [X (Twitter) MCP server](https://socialtoai.com/mcp/x.md): Let your AI read X. ## X (Twitter) post retweeters API: questions **Do I need a X account or X's own API access?** No. You only need a SocialToAI key. The call returns content and account information publicly visible on X; you never sign in to X or apply for anything there. **What does one call cost in dollars?** 2 credits: $0.0067 at 300 credits per dollar (purchases from $10), $0.004 at 500 per dollar (from $200). Credits never expire and there is no subscription. 100 free credits on sign-up, no card. **Am I charged when a call fails or finds nothing?** A failed call costs 0 credits and is never retried on its own. A call that runs and finds nothing is a successful call: status is "empty" and it costs 2 credits. This interface cannot tell a target that does not exist from one with no data, so both are charged as empty. **How much does one call return?** One call returns a page of up to 100 items. When page.has_more is true, send page.cursor back as cursor for the next page; each page costs 2 credits and a cursor works for 30 minutes. **Is there a rate limit?** 5 calls a second per key, 20 a second after your first purchase. A request over the limit is told how long to wait and is not charged. **How do I use it from Claude, ChatGPT or Cursor?** Yes. In Claude or ChatGPT, add the MCP address https://mcp.socialtoai.com/mcp as a custom connector, sign in with the code we email you and press Allow; there is no key to paste. In Claude Code, run one command, type /mcp, pick socialtoai and sign in; Codex and Cursor sign in too, with their steps on the connect page. Then ask in plain words and your AI calls call for you.
