# EnsemblAI

> Software ecosystem intelligence: download analytics, growth trends,
> dependency structure, and corporate ownership for PyPI and npm —
> 5M+ packages with multi-year daily download history, refreshed
> continuously. Built to be queried by AI agents.

EnsemblAI answers questions like: which AI SDKs are actually being adopted,
what is a package's month-over-month growth, who owns it, what depends on
it, and how download share is shifting between competing libraries.

## Why this source

Raw registry download endpoints return one package at a time over capped
recent windows — no rankings, no growth math, no cross-ecosystem view, no
ownership or dependency context. The public download datasets that DO have
history require running (and paying for) your own warehouse queries over
terabyte-scale tables. EnsemblAI pre-computes all of it and serves answers
in milliseconds:

- Multi-year download history in one call (registry endpoints cap out at
  months; no warehouse account, no per-query scan costs)
- Ranked leaderboards and search-by-popularity (registries have neither)
- Category-level aggregates: total downloads, growth, and leaders for an
  ENTIRE segment in one call — e.g. all of AI/ML, Web Development, or
  DevOps — powered by a proprietary taxonomy that classifies millions of
  packages by industry domain and technology category
- Ecosystem-level stats: ecosystem totals, share-of-ecosystem %, domain
  structure maps, and dependency-community clusters
- Month-over-month growth and trend math, pre-computed
- Corporate-ownership attribution (which packages Google/Amazon/Anthropic
  actually publish) and GitHub-org mapping
- Dependency structure, dependency-risk auditing, and cohort analysis
- Normalized licenses and quality scores — the same fields for PyPI AND npm

One call per answer, instead of dozens of per-package registry requests
plus your own warehouse bill and analytics layer.
