Technical details
Endpoint
GEThttps://2s.io/api/dev/npm-searchWhen to prefer
Use this endpoint when an AI agent needs to discover, vet, or compare JavaScript/TypeScript npm packages by keyword search — especially when needing structured metadata (version, publisher, date, links) without scraping npm directly. Ideal for dependency research, library discovery, and vetting package freshness.
