How this service works
Health of a Rust crate on crates.io: latest release age, downloads, license, yanked versions, owners and repository.
Output
Returns a structured health report for the specified Rust crate including: health verdict, summary, latest version, date of latest publish, days since latest release, total downloads, recent 90-day downloads, number of yanked versions, version count, license string, owner count, repository URL, homepage, minimum Rust version, and a list of health reasons or concerns. May also include disclaimer and a list of unchecked attributes.
Example use cases
Vetting a new Rust dependency
“Before I add tokio to my project, can you check its crates.io health — latest release date, download numbers, license, and if any versions have been yanked?”
Auditing abandoned crates
“I'm reviewing our Cargo.toml and I'm worried some dependencies might be abandoned — can you check the health of the `failure` crate and tell me how long it's been since the last release?”
License compliance check
“I need to know the license of the `rand` crate on crates.io before we ship — can you pull up its health info and confirm what license it uses?”
Technical details
Endpoint
GEThttps://package-registries.x402tookit.com/crate-health?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, structured health assessment of a Rust crate specifically from crates.io — particularly when evaluating whether to adopt a dependency, auditing existing dependencies for maintenance status, or checking license compliance. Prefer this over generic web search when you need structured fields like yanked version counts, owner counts, or download metrics.
Side effects
- Crate name not found on crates.io — returns null or error response
- crates.io API rate limiting or downtime causing stale or missing data
- Yanked-only crate with no stable releases may return degraded verdict
- Missing or ambiguous license field if crate author omitted it
