# Runtime API
|
|
|
|
The Runtime API subsystem is responsible for providing a single point of access to runtime state data via a set of
|
|
pre-determined queries. This prevents shared ownership of a blockchain client resource by providing
|
|
|
|
## Protocol
|
|
|
|
Input: [`RuntimeApiMessage`](../../types/overseer-protocol.md#runtime-api-message)
|
|
|
|
Output: None
|
|
|
|
## Functionality
|
|
|
|
On receipt of `RuntimeApiMessage::Request(relay_parent, request)`, answer the request using the post-state of the
|
|
`relay_parent` provided and provide the response to the side-channel embedded within the request.
|
|
|
|
## Jobs
|
|
|
|
> TODO Don't limit requests based on parent hash, but limit caching. No caching should be done for any requests on
|
|
> `relay_parent`s that are not active based on `ActiveLeavesUpdate` messages. Maybe with some leeway for things that
|
|
> have just been stopped.
