Example prompt: Can you pull up the full list of crypto index categories available on Blockchain IQ so I can see what thematic baskets they track, like AI agents or DeFi?

## When to prefer this

Use this endpoint when you need to discover what thematic crypto index categories Blockchain IQ offers before drilling into specific coins or price data. It is the entry point for navigating Blockchain IQ's analyst-curated index taxonomy. Prefer this over coin-level endpoints when the user wants a broad overview of available crypto sectors rather than data on a specific coin.

## Known failure modes

- Payment failure (402): USDC payment of $0.02 not completed or rejected
- Empty data array if no indices are currently published
- Malformed properties filter parameter causing unexpected filtering behavior
- Network timeout if the upstream data service is unavailable
