cex_symbol_oi

Latest Open Interest snapshot for a base asset across ALL futures venues. Returns USD-valued OI for every exchange/quote combination, sorted by USD value descending. Compact alternative to open_interest_list when focused on a single token.

Usage hints:

• base is required (e.g., BTC, ETH)
• Optional exchange filter narrows results
• Better than open_interest for cross-venue OI comparison
