How this service works
A Rust crate on crates.io: latest stable version, description, license, total and 90-day downloads, repository, docs, minimum Rust version and dates. Use to choose or audit a Rust dependency.
Output
Returns a structured object containing the crate's latest stable version, description, license, total and 90-day download counts, repository URL, documentation URL, minimum supported Rust version (MSRV), and relevant release dates — all sourced from crates.io.
Example use cases
Auditing a Rust dependency license
“Can you check the license and total download count for the tokio crate? I need to make sure it's MIT or Apache before we ship.”
Choosing between Rust HTTP clients
“Look up reqwest and hyper on crates.io for me — I want to compare their latest versions, 90-day downloads, and minimum Rust versions to decide which one to use.”
Verifying crate freshness before upgrade
“What's the latest stable version of the anyhow crate and when was it released? I want to check if it's been updated recently before upgrading our project.”
Technical details
Endpoint
GEThttps://bess-x402.onrender.com/v1/dev/crate?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative, up-to-date metadata about a specific Rust crate from crates.io — especially when evaluating a dependency for license compliance, popularity, maintenance status, or version compatibility. Prefer this over scraping the crates.io website or using the raw crates.io API directly, as it returns a clean, pre-parsed summary in a single call.
Side effects
- Crate name not found on crates.io — returns 404 or empty result
- Misspelled crate name returns no data
- crates.io API unavailable causes upstream error
- Crate exists but has no stable release — may return pre-release info or empty version field
- Missing optional fields (e.g. MSRV, docs URL) if crate author did not provide them
