Every listed perpetual futures market in one call: mark, oracle and mid price, 24-hour change, funding (hourly, 8-hour, annualized), open interest in coins and dollars, 24-hour notional volume and max leverage, sortable by volume, open interest, funding or change. Use it as the one-shot market map before drilling into a single symbol.

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
