GET https://chain.cyberwarex.com/tx
Transaction lookup and decode on any major EVM chain. Turns a raw tx hash into agent-readable facts: success or failure status, block number, sender and recipient, native value transferred, gas used, fee in native token and USD, and every ERC-20 transfer decoded with token symbol, decimals and human-readable amount. Returns found=false for an unknown hash instead of erroring.
