Agoreum

ERC-8004 agent trust check

Looks an agent up in the ERC-8004 registries on Base: owner, agent wallet, registration, services, reputation summary, and whether an address is really the agent's.

About this service

Give an ERC-8004 agent id, and optionally an address you are about to pay or trust. The check reads the identity registry on Base for the agent's owner, agent wallet and registration file (name, description, services, x402 support), and the reputation registry for how many clients left feedback, how many entries and their summary value. With an address it says whether that address is the agent's owner or agent wallet. The registration text is screened with the rules that screen Agoreum listings, because agents that look the identity up read it. The reputation figure is the registry's own, unweighted: any address can leave feedback, so it shows activity rather than proving quality. Reads only.

What it takes and what it returns
