How this service works
Rust crate profile from crates.io: version, description, license, repository, docs, total and recent downloads, minimum Rust version, keywords and dates.
Output
A JSON object containing the crate's name, latest version, description, license, repository URL, documentation URL, total download count, downloads in the last 90 days, minimum Rust version, keywords array, creation date, last updated date, and total number of published versions — all sourced from crates.io.
Example use cases
Check latest stable Rust crate version
“What's the latest version of the 'tokio' crate on crates.io, and when was it last updated?”
Evaluate crate popularity before adopting
“How many total and recent downloads does the 'reqwest' crate have on crates.io? I want to know if it's actively used before adding it as a dependency.”
Audit crate license for compliance
“What license does the 'rand' Rust crate use? Also grab its minimum supported Rust version and repository link.”
Technical details
Endpoint
POSThttps://api.vextorium.com/crates-paquete-pago?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured metadata about a specific Rust crate from crates.io, including download statistics, versioning history, licensing, and ecosystem links. Prefer this over scraping crates.io directly or using general web search when you need clean, machine-readable crate profile data for dependency evaluation, license auditing, or package discovery workflows.
Side effects
- Crate name not found on crates.io — returns null fields or error
- crates.io API is temporarily unavailable — upstream timeout or error
- Malformed crate name input — request fails validation
- Crate exists but has no published versions — sparse metadata returned
