# How do I keep track of what an account posts on X (Twitter) with AI?

Connect SocialToAI to your AI client over MCP, then ask in plain words. In this recorded run an AI client answered “What did NASA post on X this week, and which posts took off?” with 1 request on X: 21 items read in 5.5 seconds for 9 credits ($0.03). Below are the calls it made, the answer with its sources, and the prompt and API calls to run it yourself. Recorded 2026-10-18.

## The question

> What did NASA post on X this week, and which posts took off?

An account's timeline shows posts newest first, and whether a post did well depends on that account's usual numbers, which you would have to work out yourself. Reading what this run returned by hand takes about 3 minutes (600 words at 240 a minute).

## What the AI did

It chose the tools itself: 1 request on X. Each row is one tool call as the client showed it, with what it sent, how much came back and what it cost.

| Platform | Tool | Sent | Requests | Returned | Credits |
| --- | --- | --- | --- | --- | --- |
| X | [`account_watch`](https://socialtoai.com/tools/account-watch.md) | `accounts: ["https://x.com/NASA"] · window: "7d" · scale: "small"` | 1 | 21 posts | 9 |
| **Total** |  |  | 1 | 21 items | **9** |

## The answer

What the client answered, from what it had read. The line under each finding is a post it read, or a figure from those posts.

Recorded 2026-10-18

20 posts in the window; the account's usual is 1,436 interactions a post. What stands out:

1. **Posts that took off (2× the usual or more)** (20%, 4 posts): [“While observing the universe, @… caught a galaxy cluster smiling for the camera. 😊 The sm”](https://x.com/NASA/status/2109320622882873464)
2. **News** (80%, 4 posts): 4 of the 5 posts analysed
3. **Promotion** (20%, 1 post): 1 of the 5 posts analysed

Used 9 credits · $0.03. Every claim links to its source.

### The posts it rests on

A selection of what was read; the marked words are what a finding rests on. An item without a link says so.

- X · post · 7d: “While observing the universe, @… caught a galaxy cluster smiling for the camera. 😊 The smile lines are arcs caused by an effect known as gr” ([Open the source](https://x.com/NASA/status/2109320622882873464))

## What it cost

1 request, 9 credits in total: $0.03 at the $10 rate. Every answer of the API states the credits it charged and the balance left, so your AI can tell you what a question cost. A call that fails costs nothing.

| Pack | Credits per dollar | This answer |
| --- | --- | --- |
| $10 = 3,000 credits | 300 | $0.03 |
| $50 = 20,000 credits | 400 | $0.022 |
| $200 = 100,000 credits | 500 | $0.018 |

## Ask it yourself

Connect SocialToAI to your AI client once ([the steps for each client](https://socialtoai.com/mcp.md)), then paste the question. You do not name tools or parameters: the client picks them.

**Prompt**

```
What did NASA post on X this week, and which posts took off?
```

The same in code: the calls this run made, as requests to the API.

**tool.account_watch**

```
curl https://api.socialtoai.com/v1/tools/account_watch \
  -H "Authorization: Bearer $SOCIALTOAI_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "accounts": ["https://x.com/NASA"],
    "window": "7d",
    "scale": "small"
  }'
```

## What to try next

- Ask next: “Why did the top post take off?”
- Ask next: “Watch two more accounts”
- Add two competitors' accounts.
- Set it to run every week.
- Run it as one request with the ready-made tool [Account watch](https://socialtoai.com/tools/account-watch.md): What a set of accounts published lately and which posts did clearly better than each account's usual.

- [X (Twitter) MCP server](https://socialtoai.com/mcp/x.md): What your AI can read on X, and how to connect it.
- [X (Twitter) API](https://socialtoai.com/platforms/x.md): Every call on X, with its credits and a request you can copy.
