# BULK (/providers-market-data/bulk)



BULK perpetual market data uses `bulkf`. The bare `bulk` name is reserved for future Spot support.

Public market data requires no authentication. Mainnet is the default; `--testnet` selects the public testnet where the command supports network selection.

## Available [#available]
