Inspect clauses

This endpoint can be used for various purposes:

• Read contract state.
• Simulate the execution of a transaction. This can be useful to determine if your transaction may revert before submitting it.
• Inspect the outputs of a transaction before executing it.
• Estimate the gas consumption of a transaction. <b>Note:</b> The caller field should be provided for higher accuracy.

The fields gasPrice, gasPayer, provedWork, blockRef and expiration are for exposing themselves in EVM. Transaction meta features won't be reflected in the result, for example, no error is returned if the transaction is technically expired. For more information, please refer to the vechain documentation.

To access historical details, you can specify a revision as a query parameter.
