How this service works
Package intelligence across npm / PyPI / crates: latest version, age, release cadence, deprecation/yank, license, and download stats (last day/week/month) with a rising/falling trend. Aggregates the official registry + downloads API + deps.dev.
Output
A fused metadata object containing: latest version, package age, release cadence, deprecation or yank flag, license identifier, download counts for the last day/week/month, and a rising/falling download trend signal — aggregated from the official registry, downloads API, and deps.dev.
Example use cases
Evaluate dependency safety for code review
“Before we add the 'lodash' package to our project, can you check if it's still actively maintained? I need to know the latest version, when it was last released, if there are any deprecation warnings, what license it uses, and whether its download numbers are staying strong or dropping off.”
Monitor ecosystem health of core libraries
“I'm building a data pipeline and want to compare the health of three Python packages: numpy, pandas, and polars. For each one, pull their latest versions, release frequency, license info, and whether their download trends are going up or down so I can decide which has the most active community.”
Audit third-party Rust crate maturity
“We're considering integrating the 'tokio' crate into our backend. Can you give me a full picture of its health — the current version, how old the package is, how often it gets updates, whether it's been yanked or deprecated, its license, and whether downloads are trending upward?”
Technical details
Endpoint
GEThttps://payai.agentstools.dev/dev/package?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, fused snapshot of a package's health and activity across npm, PyPI, or crates.io — especially when you want version recency, deprecation status, license, and download trends in a single call without querying multiple registries manually.
Side effects
- Package not found in the specified ecosystem — returns 404 or empty result
- Invalid ecosystem value — rejected by schema validation
- Scoped npm package name malformed — query fails
- Upstream registry API unavailable — may return partial or error response
- Rate limiting or payment failure — 402 response
