# Fetch a page that needs JavaScript

Some pages fill in with JavaScript.
Your agent reads them in a real browser.

[Get the app](https://superbot.gg/download?cta%5Fid=page%5Finstall) [see the real call](https://superbot.gg/use-cases/read-a-page-that-needs-javascript#call)

## What you get

- The text of a page that fills itself in with JavaScript.
- A real browser read: the browser on your own computer when the request comes from it, else a cloud browser.
- A named reason when a page would not open.

## Ask your agent

Connect superbot once.
Other clients are on [the install page](https://superbot.gg/add).

```sh
claude mcp add --transport http superbot https://api.superbot.gg/mcp -s user
```

With no browser, post to the install route instead.

```sh
curl -fsS -X POST https://api.superbot.gg/mcp/install -d client=claude-code
```

Then ask in plain words.

```
superbot({"intent": "Read https://quotes.toscrape.com/js/page/2/ in a real browser and list the authors."})
```

This needs an account.
An agent with none signs you in through [/auth.md](https://superbot.gg/auth.md).
You read back one emailed code.

## One real call

A real call, run on 2026-10-18 from a test account.
The page draws its quotes with JavaScript.
The reply is the agent's own, with its heading and sources line cut.

call

```
superbot({"intent": "Read https://quotes.toscrape.com/js/ . It fills in with JavaScript. Give me the first three quotes with their authors."})
```

reply

```
The page rendered and here are the first three, in order:

1. "The world as we have created it is a process of our thinking. It cannot be changed without changing our thinking." - **Albert Einstein**
2. "It is our choices, Harry, that show what we truly are, far more than our abilities." - **J.K. Rowling**
3. "There are only two ways to live your life. One is as though nothing is a miracle. The other is as though everything is a miracle." - **Albert Einstein**

The JS-rendered content loaded fine in a headless browser: 10 quotes on the page, with the first three matching the order above.
```

A JavaScript page read, run live. Em dashes in the quotes are shown as hyphens.

## Limits

Pages

Public pages only.

Refusals

A page that still refuses returns the reason, such as a sign-in wall, a paywall or a rate limit. A 401 sign-in refusal and a plain rate limit are not retried in a browser, and a browser can be refused too.

Needs

A superbot account.
