Use to read any view function that has no dedicated tool (the example reads USDC totalSupply). Calldata up to 8 KB; a call that reverts is 422 with the reason, uncharged.

Estimate gas, Celo. Estimate the gas a transaction would use on Celo (eth_estimateGas) and what it would cost at the current gas price, in gas units, gwei and CELO. Give to, plus value in CELO and calldata for a contract call, and the sender when the call depends on it. Use before sending a transaction or to price a batch; for the gas price alone use celo_gas. A transaction that would revert is 422 with the reason, uncharged.
