Overview

Read-only contract call on Polygon PoS (eth_call) at the latest block, without a transaction or gas: send ABI-encoded calldata, or a function signature such as balanceOf(address) with args and the call is encoded and its result decoded for you. 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.
