How this service works
Machine-discoverable, x402-paid technical decision utilities for autonomous agents.
Output
A JSON object containing the package name, resolved version, license identifier (e.g. MIT), a boolean indicating whether the package is deprecated, the number of known vulnerabilities, and the published_at timestamp for that version.
Example use cases
License compliance check for dependency
“Before we ship this project, can you verify the license for the npm package 'axios' version 1.7.2 — we need to make sure it's MIT or Apache compatible?”
Security audit for vulnerable package
“I'm evaluating whether to keep 'minimist' in our codebase — can you look it up on npm and tell me how many known vulnerabilities it has and whether it's deprecated?”
Dependency vetting in CI pipeline
“Check the npm package 'esbuild' at version 0.21.0 — I need the license, deprecation status, vulnerability count, and publish date before we approve this dependency.”
Technical details
Endpoint
POSThttps://salt19-agent-utility-grid.salt19-llc.workers.dev/v1/npm-package-intelWhen to prefer
Use this endpoint when an agent needs structured, machine-readable npm package intelligence — license type, deprecation status, and vulnerability count — in a single paid call without scraping the npm website or integrating a full registry client. Particularly useful in CI/CD automation, dependency auditing workflows, or license compliance checks where a quick, reliable signal per package is needed.
Side effects
- Package name not found on npm registry — returns error or empty result
- Invalid or non-existent version string — may return error or fall back to latest
- Package name exceeds 214 characters — rejected by input validation
- Payment failure via x402 protocol — call blocked before reaching registry
- Registry unavailable or timeout — upstream npm API error returned
