Response element format

Each item in the list is an object with a snapshot timestamp and one field per exchange stream.

• ts — wall-clock snapshot time in milliseconds

All other fields are named {exchange}_{coin}_{market} (for example bin_btc_spot). Each holds a four-element BBA list (see below).

Exchanges and markets

Code	Exchange
byb	Bybit
bin	Binance
okx	OKX
cb	Coinbase

Markets: spot, perp.

Binance does not have a hype spot market, so bin_hype_spot is not recorded.

BBA list format

Each stream field is a four-element list of strings:

• Index 0 — bid — best bid price
• Index 1 — ask — best ask price
• Index 2 — bid_qty — best bid quantity
• Index 3 — ask_qty — best ask quantity

Sampling

Snapshots are taken every 100 ms on a wall-clock grid.

The data is recorded from AWS Tokyo (ap-northeast-1) to minimize feed latency from Asian exchange endpoints. That keeps ts timestamps close to when each BBA was observed, so snapshot times are reliable for cross-exchange comparison and backtesting.
