# Get Site Flex Events

`GET /entities/site/{site_id}/flex-events`

Get info on flex events the site has participated in, including estimated and final gross revenues.

These estimates can be used for a variety of purposes, including paying out end-users before the final settlement data is available.However, to avoid overpayments it is recommended to only pay out a percentage of the estimated revenue initially, and top-up once final revenues are available.

Note: it is possible for gross revenues to be negative in some scenarios, e.g. if the site flexed in the wrong direction by consuming more energy while it was instructed to consume less.
