How this service works
Check whether an npm or PyPI package name exists and how close it is to popular packages. Flags likely typosquats before an agent installs a dependency.
Output
Returns whether the package name exists in the specified ecosystem (npm or PyPI), a similarity score or distance metric to popular packages, a list of popular packages the name closely resembles, and a flag indicating whether it is a likely typosquat — helping agents decide whether to proceed with installation.
Example use cases
Pre-install dependency safety check
“I'm about to add 'coloers' to my Node project via npm — can you check if that's a typosquat of a popular package before I install it?”
Automated CI pipeline package vetting
“We're building a CI step that validates every new dependency. Check whether the PyPI package 'beautifulsoup5' is a typosquat or a legitimate package distinct from 'beautifulsoup4'.”
Security audit of suspicious package name
“A colleague added 'djano' to our Python requirements.txt — can you check if that's a typosquat of 'django' and how risky it looks?”
Technical details
Endpoint
GEThttps://164.160.90.241.sslip.io/api/sec-npm-pypi-typosquat-checker?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent or developer workflow needs to vet a package name for supply chain safety before installing a dependency from npm or PyPI. It is specifically suited for catching typosquatting attacks — where malicious actors register names that look like popular packages. Prefer this over a generic CVE lookup (which checks known vulnerabilities in existing packages) when the concern is package identity fraud rather than post-install vulnerability.
Side effects
- Package name not provided — returns 400 or validation error
- Unknown or unsupported ecosystem specified — may default or return error
- Package name is valid and genuinely new — low typosquat score but not necessarily safe
- Network timeout reaching the upstream package registry
- Edge case: package name is an exact match for a popular package but in a different ecosystem
