Example prompt: Can you check the current chain head on the TokenVest Genesis platform so I know the latest blockchain state?

## When to prefer this

Use this endpoint when you need the current blockchain head/tip state from the Genesis Token Labs (TokenVest) chain specifically, especially before executing pre-launch investment actions or when monitoring chain sync status in real time.

## Known failure modes

- 404 or empty data if chain head is unavailable
- Non-ok response if the chain node is unreachable or syncing
- Payment failure (402) if USDC balance is insufficient for the $0.003 call fee
- Stale or incorrect head if the underlying node is behind
