Most of the catalog is queryable for Base, from the blocks themselves to the daily activity of the projects that run on it.
The chain’s own record sits in the base dataset: one row per block, transaction, log and internal call. Everything above that sits in the catalog, where the Base rows are selected with chain_id = 'base'.
The section mirrors the catalog itself: the core entities, then the market verticals with data on Base.

Filtering
chain_id reads base in every catalog table that mentions a chain, so the same filter selects Base everywhere. Bridge transfers are the one exception: a transfer has a chain on each end and carries source_chain_id and destination_chain_id instead.
Every table splits by day: the raw and event tables on block_timestamp, the daily tables on timestamp. Bound that column in every query; without a bound the query reads the whole table.
