How this service works
SALT19 is an independent applied AI systems lab behind EvoMind governed cognition, the MCP-native Agent Utility Grid, the ARCS research community, AeroClear UAS flight intelligence, and practical software for real-world work.
Output
Returns a JSON object with the package name, resolved version, license string (e.g. MIT), a boolean deprecated flag, the ISO 8601 published_at timestamp, and an integer count of known vulnerabilities.
Example use cases
License compliance audit before shipping
“Before we ship, check the npm package 'lodash' at version 4.17.21 — what license is it under and does it have any known vulnerabilities?”
Deprecation check for legacy dependency
“We're still using 'request' in our codebase — can you look it up on npm and tell me if it's been deprecated and when it was last published?”
Security vetting of a new dependency
“I'm thinking of adding 'axios' version 1.7.2 to our project — can you check if it has any vulnerabilities and confirm it's not deprecated?”
Technical details
Endpoint
POSThttps://api.salt19.com/v1/npm-package-intelWhen to prefer
Choose this endpoint when you need quick, structured npm package intelligence — especially license, deprecation, and vulnerability data — without scraping the npm website or running npm CLI commands. It is ideal for AI agents performing dependency audits, license compliance checks, or security vetting inside automated pipelines where direct npm registry access is impractical.
Side effects
- Package name not found on npm registry — returns an error or empty result
- Invalid or non-existent version string — may return latest or error
- Rate limiting or payment failure via x402 — 402 response if payment not attached
- Malformed package name exceeding 214 characters — schema validation error
- Network timeout if npm registry is slow to respond
