This can be used to simulate a bundle against a specific block number, including simulating a bundle at the top of the next block.
Supported on Ethereum Mainnet and Goerli.
Through eth_callBundle, you can fetch the simulated bundle. txsHex is necessary. Using this api, you can send simulated bundles to miners without dealing with Flashbots, which could reduce technical costs.
