This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.
Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

## 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

## Semrush Sensor Winners & Losers Scraper

Track the domains with the largest Semrush Sensor movements by database and category. Review ranking change totals alongside tracked keyword counts and recent movement history.

### What data can you extract?

| Field | Type | Description |
| --- | --- | --- |
| `domain` | String | Website hostname with a notable Sensor movement. |
| `diff` | Integer | Net keyword ranking movement reported for this domain. |
| `keywords` | Integer | Number of tracked keywords in the Sensor report. |
| `new_keywords` | Integer | Tracked keywords newly appearing for the domain. |
| `lost_keywords` | Integer | Tracked keywords no longer appearing for the domain. |
| `date` | String | Report date returned for the selected Sensor market. |
| `category` | Integer | Sensor category identifier associated with the movement list. |
| `diffs` | Array\<Object> | Recent numeric movement history with date markers and change values. |
| `input_category` | Integer | Semrush Sensor category selected for this movement list. |
| `scraped_at` | String | UTC date and time when this record was collected. |

### Use cases

- SEO teams can spot domains with sharp visibility changes.
- Site owners can compare new and lost keyword counts by category.
- Analysts can monitor daily movement across desktop and mobile databases.

### How to use

1. Choose a Semrush database such as `US` and add category IDs to `categories`.
2. Leave `date` empty to use the current report date or provide a specific date.
3. Set `maxResults` to cap the number of domain movers saved.

```json
{
  "categories": [
    {
      "category": 1
    }
  ],
  "db": "US",
  "maxResults": 20
}
```

### Input

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `categories` | Array\<object> | Yes | Semrush Sensor category IDs to check for ranking movers. |
| `categories[].category` | integer | Yes per entry | Category sent to the source search. Allowed values: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25. |
| `categories[].db` | string | No | Database sent to the source search. |
| `categories[].date` | string | No | Date sent to the source search. When omitted, the report date defaults to two days ago, the most recent day Semrush Sensor has fully published. |
| `db` | string | Yes | Database sent to the source search. |
| `date` | string | No | Date sent to the source search. When omitted, the report date defaults to two days ago, the most recent day Semrush Sensor has fully published. |
| `maxResults` | integer | No | Maximum dataset items to save across this entire run. |

      "diff": 18
    },
    {
      "date": 1756857600,
      "diff": 24

  "scraped_at": "2026-10-01T12:00:00Z"
}
```

### Pricing

$0.30 per 1,000 results. Apify saves one dataset item per result and applies the Actor’s per-result price to saved items.

Set **maxResults** to cap the number of dataset items saved in one run.

### FAQ

#### Is scraping this information legal?

Rules depend on the source, location, data type, and intended use. Check applicable laws and source terms, and make sure your workflow follows privacy and data protection requirements.

#### What limits apply?

Submit up to 100 batch entries per run. Use **maxResults** to cap saved items. Results also depend on source availability and your Scrappa API plan.

#### Can I start runs through the Apify API?

Yes. Send a POST request to `https://api.apify.com/v2/acts/thescrappa~semrush-sensor-movers-scraper/runs` with your Actor input, or use an Apify client library. Read the output from the run dataset.

#### Can I connect the results to other tools?

Yes. Apify integrations and APIs can pass dataset results to Make, Zapier, n8n, Google Sheets, and other data workflows.

#### What happens when one input fails?

The Actor logs a short source error and continues with the remaining entries. Transient rate limits and gateway errors are retried; if every entry fails, the run reports an error.

#### Which date is used by default?

When you leave `date` empty, the Actor uses today’s date for the Sensor report.

## MCP server setup

```json

        "apify": {

            "url": "https://mcp.apify.com/?tools=fetch-actor-details,thescrappa/semrush-sensor-movers-scraper"
        }
    }
}
```

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).
