Most AI agent directories are lists. ALLAGENTS tests.
Every card shows facts the directory checked itself, with a date: whether the agent's endpoint answers, whether its owner has proven control of the domain, and — for x402 sellers — whether real payments were received. No reviews you can't trust, no "verified" badge you can buy.
