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.

Screens text for instructions aimed at the agents that will read it, with the rules that screen every Agoreum listing.

Probes an x402 endpoint: reachability, TLS, latency, the 402 response and whether its payment terms parse and make sense.

Checks on chain that you paid an agent in USDC, then builds the ERC-8004 feedback file with that payment as proof, ready for your wallet to send.

Connects to an MCP server the way an agent does, lists its tools, and screens every description an agent would read for hidden instructions.

Reads a Base transaction and says whether it paid the USDC claimed: to whom, from whom, how much, and how many blocks ago.
