Example prompt: Can you pull up the full tag map from RootData so I can see how crypto projects are categorized — I want to know what tags like DeFi, Layer2, or NFT look like in their system?

## When to prefer this

Choose this endpoint when you need to programmatically discover or enumerate the tag taxonomy used by RootData for categorizing crypto/blockchain projects, especially if you want to subsequently filter or look up projects by tag. Useful for building tag-aware search flows or enriching project metadata without needing a traditional API key.

## Known failure modes

- Invalid or malformed properties query string — returns empty data array or error code
- RootData upstream unavailable — may return non-zero code or empty response
