  ### Used By

  **Returned by**

  * [getSimulateTokenContractResults](/api-reference/queries/getsimulatetokencontractresults.md): Returns recorded token analyses, including pending and failed requests. Results are ordered by block number descending, then request timestamp descending. Use simulationId to retrieve a specific request.
  * [onSimulateTokenContract](/api-reference/subscriptions/onsimulatetokencontract.md): Live-streamed published analysis results for a token, across all simulation IDs. This is not a complete request-status stream: use getSimulateTokenContractResults to check pending, failed or indeterminate outcomes.
