How this service works
558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.
Output
Returns a JSON object with the crate name, source (crates.io), latest version, total number of versions, description, license, repository URL, documentation URL, keywords, minimum Rust version (MSRV), total download count, 90-day recent download count, creation date, and last updated date.
Example use cases
Checking crate popularity before adopting it
“What are the total and recent download counts for the 'tokio' crate on crates.io? I want to know how widely used it is before adding it as a dependency.”
Auditing open source license compliance
“I need to check the license for the 'reqwest' crate on crates.io — can you pull up its full profile so I know if it's MIT, Apache, or something else?”
Verifying MSRV for compatibility
“What's the minimum supported Rust version for the 'axum' crate? Also grab its latest version and the date it was last updated.”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/crate-package?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured metadata about a specific Rust crate by name, including popularity metrics, licensing, versioning, and MSRV — especially when you want a single-call lookup against crates.io without scraping or parsing HTML.
Side effects
- Crate name does not exist on crates.io — returns null fields or empty response
- crates.io API is temporarily unavailable — upstream timeout or error
- Typo in crate name returns no match
- Some fields (e.g. min_rust, documentation) may be null if the crate author did not provide them
