## When to prefer this

Use this endpoint when you need to programmatically retrieve the full version history of a Rust crate published on crates.io, especially in workflows that require dependency management, auditing, or selecting a specific version of a Rust library.

## Known failure modes

- Crate name not found — returns empty result or error if the crate does not exist on crates.io
- Missing or invalid 'crate' query parameter — may return an error or unexpected result
- Network/upstream crates.io API unavailable — endpoint may fail with a 5xx error
- Payment not completed — x402 payment required before response is returned
