## Get
### GetActorEvents
GetActorEvents returns all FVM and built-in Actor events that match the given filter.
This is a request/response API.
Perms: read
Inputs:
```json

{
"address": [
"f01234"

"minEpoch": 2301220,
"maxEpoch": 2301220
}
]

## Subscribe
### SubscribeActorEvents
SubscribeActorEvents returns a long-lived stream of all FVM and built-in Actor events that match the given filter.
Events that match the given filter are written to the stream in real-time as they are emitted from the FVM.
The response stream is closed when the client disconnects or if there is an error while writing an event to the stream.
This API also allows clients to read all historical events matching the given filter before
any real-time events are written to the response stream.
NOTE: THIS API IS ONLY SUPPORTED OVER WEBSOCKETS FOR NOW
