Database API

The database API is available from the full node via web-sockets.

Objects

get_objects

Get the objects corresponding to the provided IDs.

If any of the provided IDs does not map to an object, a null variant is returned in its position.

By default, API servers don’t allow subscribing to universal events, which can be changed on server startup. {% endtab %} {% endtabs %}

set_pending_transaction_callback

Register a callback handle which will get notified when a transaction is pushed to database.
