📜 Open-Source License & Dependency Audit API

Audit npm packages for license risk, dependency depth, maintainer activity, and compliance posture. One clean summary row per package — no brittle scraping, just stable registry metadata. Perfect for legal/compliance teams, engineering leads, and procurement workflows.

Store Quickstart

Run this actor with your target input. Results appear in the Apify Dataset and can be piped to webhooks for real-time delivery. Use dryRun to validate before committing to a schedule.

Key Features

• • License classification — Categorize as permissive, weak-copyleft, strong-copyleft, or unknown
• • Configurable policy — permissive (strict), copyleft-ok (tolerant), or custom allow/deny lists
• • Transitive dependency crawl — Audit nested deps up to 3 levels deep
• • Risk scoring — 0-100 score with A-F grades per package
• • Maintainer signals — Maintainer count, last publish date, deprecation status
• • Summary-first — One row per package with aggregate transitive risk

Use Cases

Who	Why
Developers	Automate recurring data fetches without building custom scrapers
Data teams	Pipe structured output into analytics warehouses
Ops teams	Monitor changes via webhook alerts
Product managers	Track competitor/market signals without engineering time

Input

Field	Type	Default	Description
packages	array	prefilled	npm package names to audit (max 200).
licensePolicy	string	"permissive"	Which license policy to apply: 'permissive' flags copyleft licenses as high risk, 'copyleft-ok' treats copyleft as mediu
allowList	array	[]	SPDX identifiers to treat as approved (only used when licensePolicy=custom).
denyList	array	[]	SPDX identifiers to treat as denied (only used when licensePolicy=custom).
maxDepth	integer	1	Maximum transitive dependency depth to crawl (0 = direct only, 1 = one level deep, etc.).
includeDevDeps	boolean	false	Also audit devDependencies of each package.
concurrency	integer	5	Number of parallel requests
timeoutMs	integer	15000	Request timeout in milliseconds

API Usage

Run this actor programmatically using the Apify API. Replace YOUR_API_TOKEN with your token from Apify Console → Settings → Integrations.

cURL

curl -X POST "https://api.apify.com/v2/acts/taroyamada~open-source-license-dependency-audit/run-sync-get-dataset-items?token=YOUR_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{ "packages": [ "express", "react", "lodash", "axios" ], "licensePolicy": "permissive", "allowList": [], "denyList": [], "maxDepth": 1, "includeDevDeps": false, "concurrency": 5, "timeoutMs": 15000, "delivery": "dataset", "dryRun": false }'

Python

from apify_client import ApifyClient

client = ApifyClient("YOUR_API_TOKEN")
run = client.actor("taroyamada/open-source-license-dependency-audit").call(run_input={

for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item)

JavaScript / Node.js

import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: 'YOUR_API_TOKEN' });
const run = await client.actor('taroyamada/open-source-license-dependency-audit').call({
  "packages": [

});

const { items } = await client.dataset(run.defaultDatasetId).listItems();
console.log(items);

Tips & Limitations

• Schedule weekly runs against your production domains to catch config drift.
• Use webhook delivery to pipe findings into your SIEM (Splunk, Datadog, Elastic).
• For CI integration, block releases on critical severity findings using exit codes.
• Combine with ssl-certificate-monitor for layered cert + headers coverage.
• Findings include links to official remediation docs — share with dev teams via the webhook payload.

FAQ

Is running this against a third-party site legal?

Passive public-header scanning is generally permitted, but follow your own compliance policies. Only scan sites you have authorization for.

How often should I scan?

Weekly for production domains; daily if you have high config-change velocity.

Can I export to a compliance tool?

Use webhook delivery or Dataset API — formats map well to Drata, Vanta, OneTrust import templates.

Is this a penetration test?

No — this actor performs passive compliance scanning only. No exploitation, fuzzing, or auth bypass.

Does this qualify as a SOC2 control?

This actor produces evidence artifacts suitable for SOC2 CC7.1 (continuous monitoring). It is not itself a SOC2 certification.
