How this service works
320+ pay-per-call API endpoints across accommodation, LLM, code execution, crypto, medical, finance, and more. One API, one payment. Powered by x402 protocol.
Output
Returns an object containing npm package metadata such as name, version, description, license, author, dependencies, download counts, and other registry information for the requested package.
Example use cases
Check package version before install
“What's the latest stable version of the 'axios' npm package and who maintains it?”
Verify package license compatibility
“Look up the npm package 'express' and tell me what license it uses — I need to confirm it's MIT before adding it to our project.”
Research unknown dependency
“I see 'chalk' listed as a dependency in my project — can you pull up its npm package info and tell me what it does and how popular it is?”
Technical details
Endpoint
POSThttps://whatchuneed.vercel.app/api/util/npm-packageWhen to prefer
Use this endpoint when an AI agent needs to quickly fetch npm package information without setting up direct npm registry API access, especially in pay-per-call agentic workflows where occasional lookups don't justify a full integration. Useful for dependency research, license checks, or version verification tasks.
Side effects
- Package name not found in npm registry returns an error result
- Misspelled or scoped package names (e.g. missing @scope/ prefix) may return no results
- Private or unpublished packages are not accessible
- Network or upstream npm registry errors may cause failures
