## 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.

## OSV-Scanner Vulnerability Checker

**Fast, lockfile-based CVE checks for any public repo — real matches from OSV.dev, Google's open vulnerability database.**

> **Verified live** against `pallets/flask`: 27 real vulnerabilities found across its `celery` example's `requirements.txt`, correctly attributed to the exact manifest file that caused them.

### Why a third scanner

[OSV.dev](https://osv.dev) aggregates PyPI Advisory DB, GitHub Security Advisories, npm advisories, RustSec, and the Go vulnerability database into one open, community-curated feed with precise affected-version-range data. Reading directly from lockfiles — instead of a full filesystem scan — makes this fast and low-noise: a useful independent cross-check alongside the Trivy and Grype scanners in this catalog, not a duplicate of either.

### Use cases

- **Fast pre-commit / pre-PR check** — lockfile-only scanning is quick enough to run on every pull request without slowing CI down.
- **Multi-ecosystem monorepo audits** — one scan covers npm, pip, Go, Rust, and more in a single pass across a polyglot repo.
- **Cross-check Trivy/Grype findings** — an independent third data source to confirm (or catch what the others miss on) a CVE.
- **Dependency upgrade planning** — see exactly which manifest file and package version triggers each finding, and what fixes it.
- **Open source contribution review** — quickly vet a project's dependency health before contributing or forking.
- **Security posture reporting** — track vulnerability count trends over time as a lightweight recurring health check.

### Input

| Field | Type | Required | Notes |
| --- | --- | --- | --- |
| `target` | string | yes | Public git repo URL |
| `severityFilter` | array | no | Restrict results to given severities |

```json
{ "target": "https://github.com/owner/repo" }
```

### Output

One row per real vulnerability match (ID, aliases, package, ecosystem, installed version, severity, fixed versions, advisory link), plus one `scan_summary` row with totals by severity and which manifest files were scanned.

One real vulnerability from a live scan against `pallets/flask`:

```json
{
  "findingType": "vulnerability",
  "target": "https://github.com/pallets/flask",
  "sourceFile": "examples/celery/requirements.txt",
  "pkgName": "click",
  "pkgEcosystem": "PyPI",
  "installedVersion": "8.1.3",
  "vulnerabilityId": "PYSEC-2026-2132",
  "aliases": ["CVE-2026-7246", "GHSA-47fr-3ffg-hgmw"],
  "severity": "UNKNOWN",
  "severityScore": "CVSS:3.1/A..."
}
```

### Frequently asked questions

**How does this differ from Trivy and Grype in the same catalog?**
It reads dependency manifests directly (requirements.txt, package-lock.json, go.sum, etc.) rather than doing a full filesystem or image scan, so it's faster and scoped to declared dependencies. OSV.dev is also a distinct data source from what Trivy and Grype use, so results are a genuine independent cross-check, not a duplicate.

**Which manifest files does it read?**
Whatever OSV-Scanner itself supports — common ones include `requirements.txt`, `package-lock.json`, `yarn.lock`, `go.sum`, `Gemfile.lock`, and `Cargo.lock`. It scans the whole repo tree, not just the root.

**What does `severity: UNKNOWN` mean?**
Not every OSV.dev advisory carries a normalized severity rating — some only publish a CVSS vector string (as in the example above) without OSV's own severity bucket. The `severityScore` field still gives you the underlying CVSS vector to interpret yourself.

**Can it scan a container image, not just a repo?**
No — this Actor is scoped to git repos and their dependency manifests. For container image scanning, use [Trivy Security Scanner](https://apify.com/ayeeyee/trivy-security-scanner) or [Grype Vulnerability Matcher](https://apify.com/ayeeyee/grype-vulnerability-matcher) in the same catalog.

### Limitations

- Only public git repos are supported — no container image scanning.
- Findings are scoped to what's declared in lockfiles/manifests; a vulnerable transitive dependency not captured in a lockfile won't be caught.
- Some advisories carry only a CVSS vector string rather than a normalized severity label (see FAQ above).

### Start scanning

Give it a public repo URL and run it — pair it with Trivy or Grype on the same target if you want image-level coverage alongside manifest-level checks.

### Pricing

Pay per completed scan (Pay-Per-Event) — **$0.49 per scan**, charged once the scan finishes regardless of how many matches are fou
