# call

To prevent API abuse, the `gas` parameter in [`eth_estimateGas`](https://slice-ledger.gitbook.io/sliceledger/api/broken-reference) and [`eth_call`](https://slice-ledger.gitbook.io/sliceledger/api/broken-reference) is capped at 10x (1000%) the current block gas limit. You can recreate this behavior in your local test environment (Ganache, Besu, Geth, or other client) via the `rpc.gascap` command-line option.
