npm Package Stats & Metadata
Pricing
$0.40 / 1,000 packages
npm package scraper for dependency and package research. Export registry metadata as JSON with optional download totals or daily download records.
You can access the npm Package Stats & Metadata programmatically from your own applications by using the Apify API. You can also choose the language preference from below. To use the Apify API, you’ll need an Apify account and your API token, found in API & Integrations in Apify Console.

It simplifies API development, integration, and documentation.
OpenAPI is effective when used with AI agents and GPTs by standardizing how these systems interact with various APIs, for reliable integrations and efficient communication.
By defining machine-readable API specifications, OpenAPI allows AI models like GPTs to understand and use varied data sources, improving accuracy. This accelerates development, reduces errors, and provides context-aware responses, making OpenAPI a core component for AI applications.
You can download the OpenAPI definitions for npm Package Stats & Metadata from the options below:
