CLOB markets

client.markets.list({ structure: 'clob' }) — order-book markets from the second indexer. Live on mainnet and testnet (mainnet linked 2026-08-11). Prices are the merged-book mid, never the last trade.

Live on mainnet and testnet. Reads here, and the write path is proven on-chain — trading is on the CLOB trading page; this one stays a read surface.

A price shown here is the mid of the best bid and ask. When the book is empty or one-sided — routine on a 15-minute market that has just opened — the API falls back to a fresh last trade, then the prior market in the series, then 50/50. It never presents the last trade as the live price.
