Returns open, high, low, close, volume and, where the exchange reports it, the trade count per candle. Timestamps are always the opening time of the candle in UTC milliseconds. The last candle is usually still forming: it is delivered but marked, and complete=false says so at the top level, with las

Walks the visible book of every requested exchange for the given size, in both directions, and works out what remains of the raw spread: gross_spread_bps from top of book, then the taker fee of the entry tier on both sides, then the slippage the size causes on the buy book and on the sell book. net_

Compares the volume of the most recent completed minute candle with the distribution of minute volumes over the chosen lookback, taken from the history this hub records itself every minute. Median and median absolute deviation are used instead of mean and standard deviation because volume is skewed.

Measures the state of one pair over the chosen horizon from the minute candles this hub records itself: annualized realized volatility from log returns, trend strength as path efficiency between -1 and +1, average true range, and the drawdown from the highest high in the window. regime is a classifi

Builds the universe from the Binance spot USDT pairs ranked by 24 hour turnover and states that criterion in universe_source, because a breadth number without its universe is meaningless.

Reads the public perpetual data of Binance USDⓈ-M Futures, Bybit linear and OKX swaps for one BASE/QUOTE pair.

Reads the dated futures of Deribit for BTC or ETH and compares each expiry with a spot price whose source is always named in the answer, because a basis computed against a different venue than the future is a different number. By default the Deribit index is used, which sits on the same venue as the

Compares the open interest recorded now with the value this hub recorded itself at the start of the window, so both numbers come from the same source and the same basis.

Reads the public option book summaries of Deribit and aggregates them per expiry. iv_atm is the mark implied volatility of the strike closest to the forward, averaged over call and put, and the strike used is named. term_structure lists iv_atm against days to expiry. put_call_ratio is reported twice

Quotes each stablecoin against real US dollars on Kraken and Coinbase and, separately, against USDT on Binance, OKX and Bybit.

Reads eth_feeHistory over the last ten blocks with reward percentiles 25, 50 and 75, and falls back to eth_gasPrice when a node does not serve fee history. base_fee_gwei is the base fee of the next block, not of the last one, because that is the fee a transaction sent now will actually pay. recommen

Takes a chain key and a contract address, or one of a short list of globally unambiguous symbols. A symbol that is not on that list is refused with 400 and a pointer to the address rather than resolved to a guess: the same ticker exists on every chain, and the imitations carry it deliberately. price

Measures how much bridged capital sits on a chain and how that changed. bridged_usd is the sum of canonical and external value: what came in over the canonical bridge of the chain plus what third party bridges brought, while natively issued value is reported apart because it never crossed a bridge.
