eth_call runs a contract function as a pure simulation against a chosen block's state. BNB Smart Chain, the BNB-native geth-equivalent EVM that hosts PancakeSwap and Venus, executes the bytecode locally and hands back the ABI-encoded output. Nothing is broadcast. No validator includes the call, and not a single wei of BNB leaves the caller's account. Send the request to https://bsc.therpc.io/YOUR_API_KEY at chain ID 56, and the result matches exactly what the contract would have produced on-chain.

| Type | Description |
|---|---|
| string | Hex-encoded return data from the executed function. Decode with the contract ABI. If the call reverts, an error with code -32000 or 3 is returned instead. |

| Code | Message | Cause |
|---|---|---|
3 | execution reverted | The EVM reverted the call. Error data contains the revert reason. |
-32602 | invalid argument | Malformed transaction object or missing required `to` field. |
-32000 | execution reverted | Node-level revert without revert data (e.g. out-of-gas within the call, or require with no message). |
latest reflects that instant only. With ~3s BSC blocks, state can shift before your transaction is mined, so treat the value as advisory rather than a promise.Paramètres
