- Status
summary: Returns information about the current state of the child chain and the watcher.
description: |
The most critical function of the Watcher is to monitor the ChildChain and report dishonest activity. The user must call the `/status.get` endpoint periodically to check. Any situation that requires the user to either exit or challenge an invalid exit will be included in the `byzantine_events` field.

- Account
summary: Gets all utxos belonging to the given address.
description: |
**Note:** this is a performance intensive call and should only be used if the chain is byzantine and the user needs to retrieve utxo information to be able to exit. Normally an application should use the Informational API's [Account - Get Utxos](http://TODO) instead. This version is provided in case the Informational API is not available.
