Api access to execution log

Question

I want to be able to with one node to get all data gathered in a execution to be saved at a external api.

Other option:

n8n would expose a api to get that data

I know i could do that with one http-reqest node, and manually collect all the data i want, but that is a unneccessary and tedious task.

Obviously n8n has a storage of that data, so i just want something give me all the data
collected in a execution to be saved for later usage.

Use Case

Mostly audit logging to answer queries like

who started the workflow?

Who/what was the subject

Who did interact at which point in time
