#![allow(clippy::print_stdout)]
//! Query an agent's on-chain identity from the ERC-8004 Identity Registry.
//!
//! Usage:
//!   cargo run --example `query_agent`
//!
//! This example connects to Ethereum mainnet via a public RPC endpoint and
//! reads basic identity information for a given agent ID.
