## When to prefer this

Use this endpoint first when building a workflow that queries Octav for wallet holdings, NAV, DeFi protocols, or token approvals — it lets you discover which chains are available before constructing chain-specific queries. Prefer this over hardcoding chain names.

## Known failure modes

- Invalid properties parameter returns 400 error
- API authentication or payment failure returns 402
- Service unavailable returns 503
- Empty result if no chains configured
