## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

### What is CSS Selector Extractor (any page, any field)?

CSS Selector Extractor (any page, any field) is an Apify Actor that turns a list of **URLs** and a list of **CSS selectors** into structured data — no scraper to write, no browser to configure. Give it a page and tell it "get the text at `.price`" or "get the `href` at `a.download-link`" and it returns **one clean row per URL** with exactly the values those selectors matched. It is the generic "scrape this bit of this page" tool people reach for before writing a custom Cheerio or Playwright script, and it works on any static HTML page — product pages, blog posts, directories, documentation, internal tools — using plain HTTP requests, not a headless browser. Runs on Apify's schedule, webhook and API infrastructure, so checking the same selectors across a list of pages on a timer is a five-minute setup.

### What data does CSS Selector Extractor extract?

For every URL, the Actor runs each configured selector against the page and returns:

| Field                       | Type           | Description                                                                                               |
| --------------------------- | -------------- | --------------------------------------------------------------------------------------------------------- |
| `url`, `finalUrl`           | string         | The input URL and the URL after following redirects                                                       |
| `statusCode`, `contentType` | number, string | HTTP status code and Content-Type header of the fetched page                                              |
| `fields`                    | object         | One key per selector `name` — a string, an array of strings, or a number for `count`                      |
| `matchCounts`               | object         | One key per selector `name` — how many DOM nodes that selector actually matched                           |
| `htmlSizeBytes`             | number         | Size of the fetched HTML in bytes                                                                         |
| `usedProxy`                 | boolean        | Whether this URL needed Apify Proxy to load                                                               |
| `error`                     | string         | Set when the URL could not be fetched or parsed; every other field but `url` and `scrapedAt` stays `null` |
| `scrapedAt`                 | string         | Timestamp of the fetch (ISO 8601 UTC)                                                                     |

### How to use CSS Selector Extractor

1. Fill **URLs** with one page per line — product pages, articles, directory listings, anything with static HTML.
2. Fill **Selectors** with a JSON array of `{"name", "selector", "type"}` objects. `type` is one of `text` (element text), `html` (element's outer HTML), `attr` (an attribute value — add `"attribute":"href"` or similar) or `count` (how many nodes matched, no value extraction).
3. Leave **First match only** on to get one value per selector, or turn it off to get every match as an array (capped by **Max matches per selector**).
4. Click **Start** and export the dataset as JSON, CSV, Excel or HTML from the **Output** tab — one row per URL, ready to join, chart or feed into another system.

### Example input

```json
{
    "urls": ["https://example.com", "https://apify.com"],
    "selectors": [
        { "name": "title", "selector": "h1", "type": "text" },
        { "name": "canonicalUrl", "selector": "link[rel='canonical']", "type": "attr", "attribute": "href" }
    ],
    "firstMatchOnly": true,
    "trimWhitespace": true
}
```

### Example output

```json
{
    "url": "https://news.ycombinator.com/",
    "finalUrl": "https://news.ycombinator.com/",
    "statusCode": 200,
    "contentType": "text/html; charset=utf-8",
    "fields": {
        "firstTitle": "Show HN: A CSS selector scraper",
        "firstLink": "https://example.com/show-hn",
        "storyCount": 30
    },
    "matchCounts": {
        "firstTitle": 30,
        "firstLink": 30,
        "storyCount": 30
    },
    "htmlSizeBytes": 34611,
    "usedProxy": false,
    "error": null,
    "scrapedAt": "2026-09-14T01:57:46.921Z"
}
```

A URL that fails to load or parse still produces exactly one row, with `error` set and every other field `null` — a bad URL or a typo'd selector never crashes the run or leaves a URL missing from the dataset.

### Pricing

CSS Selector Extractor uses pay-per-event pricing: **$0.001 per result row**, plus a negligible actor-start fee. Extracting five selectors from 100 URLs costs about ten cents, whether one selector matches or five do — the price is per URL, not per field. Set **Maximum cost per run** and the Actor trims the URL list to what the budget covers instead of overspending.

### CSS Selector Extractor vs. writing your own scraper

A one-off Node or Python script with Cheerio or BeautifulSoup can do the same extraction, but it means writing fetch/retry/timeout logic, a proxy fallback, whitespace cleanup and a dataset writer from scratch for every new site. This Actor already handles retries, direct-first proxy escalation on a block, and a guaranteed one-row-per-URL output shape — describe the fields once as a small JSON list and get a typed dataset back, schedulable and API-callable without touching code.

### Using CSS Selector Extractor with AI agents and MCP

CSS Selector Extractor is pay-per-event with limited permissions — the two requirements for an Actor to be callable through the Apify MCP server at `mcp.apify.com`. An agent that needs one specific value off a page (a price, a title, a status, a download link) can call this Actor directly with a `urls` list and a `selectors` array instead of fetching and parsing HTML itself, and gets back a typed row with the value already extracted, trimmed, and counted.

### FAQ

**Does this use a headless browser?** No. It fetches HTML with plain HTTP requests and parses it with Cheerio, which is far faster and cheaper than a browser but means it cannot extract content that is only added by client-side JavaScript after the initial page load.

**What happens if my selector matches nothing?** That is not an error — the field's value is `null` and its `matchCounts` entry is `0`. Only a fetch failure (bad URL, timeout, non-2xx status) or an unparseable response sets the row's `error`.

**What does `type: "count"` do?** It returns how many elements the selector matched as a number, ignoring `firstMatchOnly` — useful for "how many products/comments/results are on this page" without extracting any text.

**Why is my `attr` field null even though the element exists?** Either `attribute` was left out of that selector's definition, or the matched element simply doesn't have that attribute set — both return `null` rather than throwing.

**Why did a site return blocked or empty content?** Some sites answer bot traffic with a challenge page even at HTTP 200. With `proxyMode` set to `auto` (the default), the Actor detects that content and retries the rest of the run through Apify Proxy automatically — no proxy spend unless a block is actually detected.

**Is this legal to run?** Extracting publicly visible page content for your own use is common practice, but you are responsible for complying with the target site's Terms of Service and applicable law (e.g. `robots.txt`, copyright, personal-data rules) for your specific use case.

**What are the limitations?** No JavaScript rendering, up to 25 selectors per run, and up to 500 matches returned per selector even when `firstMatchOnly` is off. A failing URL still produces a row, with the reason in `error`.

# Actor input Schema

## `urls` (type: `array`):

Enter one URL per row to fetch and run the selectors against, e.g. https://example.com. Each URL gets exactly one result row, even if the fetch fails.

## `selectors` (type: `array`):

Enter the fields to extract as a JSON array of {"name", "selector", "type"} objects. "type" is one of text, html, attr or count; an "attr" entry also needs "attribute" (e.g. {"name":"canonicalUrl","selector":"link\[rel='canonical']","type":"attr","attribute":"href"}). Capped at 25 entries per run.

## `firstMatchOnly` (type: `boolean`):

Keep this on to return only the first element each selector matches. Turn it off to return every match (up to Max matches per selector) as an array.

## `maxMatchesPerSelector` (type: `integer`):

Enter the most matches to return for one selector when First match only is off, e.g. 20. Does not limit the reported match count, only how many values are returned.

## `trimWhitespace` (type: `boolean`):

Keep this on to collapse runs of whitespace and trim the ends of extracted text and attribute values. Turning it off returns text and attr values exactly as found in the page.

## `maxConcurrency` (type: `integer`):

Enter how many URLs to fetch in parallel, e.g. 5. Lower this if a target site starts returning errors under load.

## `proxyMode` (type: `string`):

'auto' (recommended) requests each URL directly first and only switches to Apify Proxy for the rest of the run if a direct request gets blocked — this keeps proxy cost at $0 whenever a site isn't blocking datacenter IPs. 'always' skips the direct attempt and always uses the proxy. 'never' always requests directly, even if that means errors.

## `proxyConfiguration` (type: `object`):

Which Apify Proxy group to use when 'Proxy mode' above decides a request needs the proxy (either 'auto' after a block, or 'always'). Leave Residential proxy selected (the default) unless you know a datacenter group works for your target. Not needed when running locally with your own IP.

## `inputDatasetId` (type: `string`):

Take the items from another Actor run's dataset, e.g. "aBcD1234". Combined with the list above.

## `inputField` (type: `string`):

Column holding the value, e.g. "url" (the default). Array columns are flattened.

## `results` (type: `string`):

All extracted fields per URL — download as JSON, CSV, Excel or HTML.

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "urls": [
        "https://example.com",
        "https://apify.com"
    ],
    "selectors": [
        {
            "name": "title",
            "selector": "h1",
            "type": "text"
        },
        {
            "name": "canonicalUrl",
            "selector": "link[rel='canonical']",
            "type": "attr",
            "attribute": "href"
        }
    ],
    "firstMatchOnly": true,
    "maxMatchesPerSelector": 20,
    "trimWhitespace": true,
    "maxConcurrency": 5,
    "proxyMode": "auto",
    "proxyConfiguration": {
        "useApifyProxy": true,
        "apifyProxyGroups": [
            "RESIDENTIAL"
        ]
    }
};

// Run the Actor and wait for it to finish
const run = await client.actor("webdatatools/css-selector-extractor").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = {
    "urls": [
        "https://example.com",
        "https://apify.com",
    ],
    "selectors": [
        {

            "type": "text",
        },
        {
            "name": "canonicalUrl",
            "selector": "link[rel='canonical']",
            "type": "attr",

    },
}

# Run the Actor and wait for it to finish
run = client.actor("webdatatools/css-selector-extractor").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

```bash
echo '{
  "urls": [
    "https://example.com",
    "https://apify.com"
  ],
  "selectors": [
    {
      "name": "title",
      "selector": "h1",
      "type": "text"
    },
    {
      "name": "canonicalUrl",
      "selector": "link[rel='\''canonical'\'']",
      "type": "attr",
      "attribute": "href"
    }
  ],
  "firstMatchOnly": true,

    "apifyProxyGroups": [
      "RESIDENTIAL"
    ]
  }
}' |
apify call webdatatools/css-selector-extractor --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,webdatatools/css-selector-extractor"
        }
    }
}
```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
