DeepBook: Market reads

Purpose

DeepBook v3 is Sui's shared order book. Mysten runs a free public indexer — no key, no wallet:

Pair names are BASE_QUOTE (e.g. SUI_USDC, DEEP_USDC, WAL_USDC). Get the live list from /get_pools.

Rules

1. Discover pairs first. Pool names are exact — call /get_pools or /ticker before assuming a pair exists.
2. Prices come pre-scaled. Ticker/orderbook/candle prices are already in human units — don't re-divide by decimals.
3. Check isFrozen. A ticker entry with isFrozen: 1 is an inactive pool — don't quote it as a live price.
4. This is one venue. DeepBook depth ≠ all of Sui liquidity. For a best-execution swap across 20+ DEXs, use the t2000-swap skill; use DeepBook reads for order-book-grade data.
