## Table description

The `polkadot.calls` table represents *internal* calls within Substrate extrinsics, including recursive calls from `proxy` and `utility` (batch) pallets, and provides detailed call arguments at each level of the call tree. Unlike the `extrinsics` table which only captures the top-level call, this table exposes the full call hierarchy.

Common queries on the `calls` table will typically filter on `block_time`, `call_section` and `call_method` and extract JSON encoded information in
`data` or `decoded_data`.
