## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
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.
Actors are written with capital "A".

## 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.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## OSV Open Source Vulnerabilities Scraper

**Get clean open-source vulnerability data for any package across npm, PyPI, Go, Maven, crates.io, RubyGems, NuGet, Packagist, Hex & Pub: CVE/GHSA aliases, CVSS severity, affected versions and references. Powered by OSV.dev. As JSON, CSV or Excel. Free, no key, no proxy.**

### 💵 Pricing

**Pay per result — ~$1 per 1,000 items.** No subscription, no proxy needed. You only pay for the data you scrape, and new Apify accounts include free monthly credits so you can test it for **$0**.

### 🔎 What can it extract?

- Vulnerability **id** (OSV/GHSA) and **CVE/GHSA aliases**
- **Summary** and full **details**
- **CVSS severity** vector or label (CRITICAL/HIGH/MODERATE/LOW)
- **Affected versions** (explicit versions + introduced/fixed ranges)
- Package name and ecosystem
- Published / modified dates and **reference URLs**
- Direct link to `osv.dev/vulnerability/{id}`

### 🚀 How do I use it?

1. Click **Try for free**.
2. Choose a mode: **packages** (scan package names in an ecosystem) or **ids** (fetch specific CVE/GHSA/OSV ids).
3. Click **Start** and download results as JSON, CSV or Excel — or pull them via the API / schedule them.

### ⚙️ Input example

```json
{
  "mode": "packages",
  "ecosystem": "npm",
  "packageNames": ["lodash", "django"],
  "maxItems": 100
}
```

By id:

```json
{
  "mode": "ids",
  "vulnIds": ["GHSA-29mw-wpgm-hmr9"]
}
```

### 📦 Output example

```json
{
  "id": "GHSA-29mw-wpgm-hmr9",
  "aliases": ["CVE-2020-28500"],
  "package": "lodash",
  "ecosystem": "npm",
  "severity": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L",
  "affected_versions": ["introduced: 4.0.0", "fixed: 4.17.21"],
  "url": "https://osv.dev/vulnerability/GHSA-29mw-wpgm-hmr9"
}
```

### 🎯 Use cases

- **Dependency scanning** — flag vulnerable packages in your lockfiles
- **Security** — monitor advisories for the libraries you ship
- **SBOM** — enrich software bills of materials with known CVEs
- **Compliance** — evidence for audits and vulnerability reporting

### 💰 How much will it cost?

You pay only the per-result price (no proxy cost):
100 → ~$0.10 · 1,000 → ~$1 · 10,000 → ~$10

### 🆚 Why this one

| Feature | This actor | Others |
|---|---|---|
| 10+ ecosystems (npm/PyPI/Go/Maven…) | ✅ | often one |
| CVE + GHSA aliases | ✅ | partial |
| Affected version ranges | ✅ | rarely |
| No key needed | ✅ | sometimes |

## CLI example

```bash
echo '{
  "ecosystem": "npm",
  "packageNames": [
    "lodash",
    "django"
  ],
  "vulnIds": [
    "GHSA-29mw-wpgm-hmr9"
  ],
  "maxItems": 100
}' |
apify call ninhothedev/osv-scraper --silent --output-dataset

```

## MCP server setup

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