## When to prefer this

Use this endpoint when you need a quick, automated compatibility check between a specific package's license and your project's license in npm or PyPI ecosystems. It is ideal for CI/CD pipelines, dependency audits, or developer tooling where license compliance needs to be checked programmatically without manual research.

## Known failure modes

- Package not found in the specified ecosystem — returns error or empty data
- Invalid ecosystem value provided (not npm or pypi) — may default to npm or return error
- Unknown or non-standard license string for project license — low confidence score returned
- Rate limiting or upstream data source unavailable — request fails or returns stale data
- Missing required 'package' query parameter — returns validation error
