Example prompt: What are the runtime and platform constraints for the koa npm package — specifically, which Node.js versions and platforms does it support?

## When to prefer this

Choose this endpoint when you need structured, programmatic access to koa's runtime and platform constraints from npm registry metadata — particularly for automated upgrade planning, CI/CD compatibility checks, or environment audits. Prefer it over manually reading package.json or npmjs.com when you need machine-readable output in an agent workflow.

## Known failure modes

- Unknown package name returns empty or error response
- Invalid version string returns an error or no data
- Network timeout if registry metadata is unavailable
- Requested version does not exist in the npm registry
- Package has no explicitly declared engine constraints, returning partial data
