simulation is described under Simulation: raw bytes holding UTF-8 JSON text in a network-specific form, for reference only.
A successful re-run replaces the stored simulation with the result of the run. If the simulation provider returns an error, or the organization’s simulation allowance is used up, the call still succeeds and simulation is empty. A simulation that does not finish within 5 seconds fails a custom transaction with an error, and returns the earlier stored simulation for a dApp transaction. A returned simulation therefore does not show that it was just re-run.
The request must be pending, belong to a vault the API token can access, and have been created by the same API user. Only custom transactions and EVM dApp transactions are simulated; for any other request simulation is empty.
