Query parameters

chains: Filters the data by chain.
from_block: Filters the data by a starting version. As Move chains use a per-transaction versioned database, we use version interchangably with block_number and omit blocks altogether.
to_block: Filters the data by an ending version. As Move chains use a per-transaction versioned database, we use version interchangably with block_number and omit blocks altogether.
