How this service works
Search npm package registry — find JavaScript and TypeScript libraries, frameworks, and developer tools. AI agent API for dependency research. Accepts USDC payments on Base and Solana
Output
Returns an array of npm package objects each with: package name, composite score (final score plus quality/popularity/maintenance sub-scores), npm URL, latest version, description, keywords, publisher, repository URL, homepage, and last updated timestamp. Results are ordered by relevance/score descending.
Example use cases
Example prompt
“Search npm for HTTP client libraries — show me the top 10 results scored by popularity and maintenance quality.”
Technical details
Endpoint
GEThttps://scout.hugen.tokyo/scout/npmWhen to prefer
Use this endpoint when an AI agent needs to research JavaScript or TypeScript dependencies, evaluate package health metrics, discover libraries for a specific use case, or verify the latest published version of an npm package. Prefer over manual npmjs.com browsing when automating dependency research or comparing multiple packages programmatically.
Side effects
- Empty result set if query term matches no packages
- Payment required (402) if USDC payment on Base or Solana is not attached
- Rate limiting or timeout if npm registry is slow
- Malformed query returns error response
- per_page value out of allowed range returns validation error
