How this service works
Trust check an npm package before an agent installs it: typosquat screen, deprecation, package age, maintainers, weekly downloads, source link.
Output
Returns a structured trust report for the given npm package including: whether the package name looks like a typosquat of a popular package, whether it is deprecated, how old the package is, a list of maintainers, weekly download count, and a link to the source repository.
Example use cases
Typosquat screen before dependency install
“I want to add 'expres' as a dependency — can you trust-scan it first to see if it looks like a typosquat of 'express' and whether it's safe to install?”
Vetting a new open-source library
“Before I add 'axios-fetch-adapter' to our project, can you check its npm trust score — deprecation status, package age, maintainers, and weekly downloads?”
Agent auto-installing packages safely
“My build agent is about to install 'coloers' from npm — please run a typosquat and trustworthiness check on it before it proceeds.”
Technical details
Endpoint
POSThttps://aiagentscity.com/api/x402/trustscan/npm?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent or automated pipeline is about to install or recommend an npm package and needs a quick, structured trust signal before proceeding. Prefer this over manual npm lookups when you need typosquat detection combined with deprecation, age, and maintainer signals in a single API call, especially in agentic workflows where supply chain safety is a concern.
Side effects
- Package name not found on npm registry — returns not-found error
- Malformed or empty package name input — returns validation error
- npm registry API unavailable — returns upstream timeout or service error
- Ambiguous package name with no clear typosquat match — returns low-confidence flag
