How this service works
Rust crate facts from crates.io: version, downloads, repo — Genesis402 / UnyKorn Operator Network
Output
Returns structured metadata for the requested Rust crate from crates.io, including the latest published version string, total all-time download count, and the associated source repository URL (typically a GitHub link).
Example use cases
Check dependency version before upgrading
“I'm updating my Cargo.toml — what's the current published version of serde on crates.io and where's its source repo?”
Research crate popularity for evaluation
“We're evaluating Rust HTTP clients — can you look up the download count and repo link for the reqwest crate on crates.io?”
Verify crate exists before publishing
“Before I publish my new crate, check if 'hyper' already exists on crates.io and tell me its latest version and total downloads.”

Endpoint
POSThttps://twin.unykorn.org/research/crates-package?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need quick, structured facts about a Rust crate — specifically version, downloads, and repo — without scraping crates.io yourself. Prefer it over general web search when you need machine-readable crate metadata to enrich developer tooling, dependency audits, or package comparison workflows.
Side effects
- Crate name not found on crates.io returns an error or empty result
- crates.io API rate limiting or downtime causes lookup failure
- Typos or incorrect crate names return no results
- Crate exists but has no associated repository URL
