Technical details
Endpoint
POSThttps://clonecho.builda.company/x402/crates-packageWhen to prefer
Use this endpoint when you need structured metadata about a specific Rust crate by name — particularly download statistics, latest version, or categorization — without scraping crates.io directly. Prefer this over general web search when you need structured, machine-readable JSON output about Rust packages.
Side effects
- Crate name not found — returns error or empty result
- Missing or malformed ?crate= query parameter
- Payment failure via x402 protocol — returns 402 status
- Network timeout or upstream crates.io unavailability
