How this service works
Check dependencies before your coding agent installs them: up to 20 packages per call (npm, PyPI, crates.io, Go, Maven, NuGet, RubyGems), one decision each: ALLOW, CAUTION or BLOCK with reasons. Catches hallucinated package names that do not exist (slopsquatting), known malware (OSV malicious-package feed, including versions already removed from the registry), typosquats one typo away from a popular package, critical and high vulnerabilities in the exact version with a safe upgrade, deprecated…
Output
Returns a JSON object with a success flag and a data field containing per-package security findings, including known vulnerabilities, CVEs, malware flags, and risk assessments for each checked package or dependency listed in the manifest.
Example use cases
Pre-install security scan for a single package
“I'm about to add 'axios@0.21.1' to my Node.js project — can you check if it has any known vulnerabilities before I install it?”
Audit Python requirements file before deployment
“Here's my requirements.txt — can you scan all these Python packages for known security issues or CVEs before I deploy? requests==2.28.0
flask==2.0.1
numpy==1.21.0”
Verify legacy Java dependency safety
“We're using log4j-core version 2.14.1 as a Maven dependency — is it safe or does it have known exploits like Log4Shell?”
Technical details
Endpoint
POSThttps://agentsvc.io/api/v1/proxy/package-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to programmatically check package safety across multiple ecosystems (npm, PyPI, Go, Maven, Cargo, NuGet, RubyGems) without setting up an account or API key. It is especially useful for automated CI-adjacent agents, dependency auditing workflows, or any agent that needs to verify a package before recommending or installing it. Prefer this over manual CVE lookups when you need structured, machine-readable output per call and want to pay only per use without a subscription.
Side effects
- Unknown package name returns empty or not-found result
- Unsupported ecosystem prefix causes parsing error
- Manifest file exceeds 100,000 character limit and is rejected
- Invalid version range string fails validation
- Packages array exceeds 20-item limit
- Network or upstream vulnerability database unavailable returns error
