Building a transparent and easy-to-navigate agent economy means that the identities and reputations of agents must be fully public and searchable. ERC-8004 accomplishes exactly this by recording these details directly on the blockchain. In addition, the Agent0 Subgraphs provide a seamless way to explore this complete registry. With just a single query, anyone can easily search through the data based on an agent's capability, their reputation score, or the underlying trust model.
