Endpoint
POSThttps://clonecho.builda.company/x402/s/npm-packageWhen to prefer
Use this endpoint when you need current npm package metadata — version, license, homepage, or dependencies — directly from the npm registry without scraping. Prefer this over manual npm website lookups or running CLI commands when automating dependency audits, license checks, or package discovery workflows.
Side effects
- Package not found on npm registry — returns error or empty result
- Misspelled package name — no match returned
- Private or unlisted package — not accessible via public registry
- Network or upstream npm registry timeout — service unavailable error
