## Pricing

from $2.99 / 1,000 results

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

## Open VSX Extensions Scraper: Open VSX Extensions Search

This Open VSX extensions scraper helps you gather detailed extension information into clean, structured data. You can easily search by keywords, pull details for a specific extension using its ID, or extract every extension published under a given namespace. Once collected, export your dataset in JSON, CSV, or Excel formats.

### Use Cases

- **Extension search**: Look up extensions like `python`, sort them by downloads, and capture ratings, review counts, and version details.
- **Single extension target**: Pass a specific extension ID (e.g., `ms-python.python`) to pull display names, download numbers, and download links.
- **Publisher extraction**: Input a publisher namespace like `redhat` to list every extension under that account.
- **Controlled extraction**: Set a maximum item limit (`maxItems`) before exporting to spreadsheets to keep your dataset focused and manageable.

### What Data Does This Tool Extract?

The scraper extracts key details for each extension record, including:

- Extension name, display name, and namespace
- Download counts, average ratings, and review counts
- Extension descriptions and version timestamps
- File download links (icon and package files)
- Verification status and deprecation flags

If a specific extension ID cannot be found during a run, the actor records an error row for that entry and continues collecting the remaining items without stopping the run.

### Input

| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|
| `searchQueries` | array | `python` | Keywords to search for (one per line). |
| `extensionIds` | array | empty | Specific extension IDs in `namespace.name` format (e.g., `ms-python.python`). |
| `namespaces` | array | empty | Publisher namespaces (e.g., `redhat`). |
| `sortBy` | string | `relevance` | Sort results by `relevance`, `timestamp`, `downloadCount`, or `averageRating`. |
| `maxItems` | integer | 100 | Total rows to collect (up to 1000). |
| `requestDelaySecs` | number | 0.3 | Pause duration between requests. |
| `timeoutSecs` | integer | 300 | Maximum total runtime in seconds. |
| `requestTimeoutSecs` | integer | 30 | Maximum wait time for a single response. |
| `proxyConfiguration` | object | `{"useApifyProxy": false}` | Proxy settings (optional). |

### How It Works

1. **Input check**: Reads search queries, extension IDs, or namespaces. If none are provided, it defaults to searching for `python`.
2. **Data retrieval**: Fetch matches, paging through search results according to your `maxItems` setting.
3. **Deduplication**: Automatically removes duplicate entries (`namespace.name`) before outputting items to your dataset.

### FAQ

**Can I export data as CSV?**
Yes. You can export dataset results in JSON, CSV, or Excel formats directly.

**How fresh is the data?**
Every run pulls data in real-time. The `scraped_at` timestamp shows exactly when each record was collected.

**What happens if an extension ID isn't found?**
Instead of stopping the run, the scraper logs an error record for that specific ID and moves on to collect the rest.

**How many rows can I collect per run?**
`maxItems` defaults to 100, but you can set it anywhere up to 1000 items per run.

    "useApifyProxy": false
  }

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,b2b_lead_generation/open-vsx-extensions-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).
