Description

4.4.1.3 Query Bundle Data

This API enables MEV data analysts to query bundle information from builders.
It is particularly useful for MEV data providers who need to analyze market trends and create analytics dashboards.
For instance, to accurately measure MEV market activity, providers can use this API to display metrics such as
daily bundle counts and bundles per block in their analytics panels.
