Best for: Developers building agents that deal with other agents

AgentStamp addresses a new problem: how can your AI agent know whether to trust another agent it has never met? It certifies agent identity and builds a reputation record, so agents from different organisations can check each other before working together.

You can look up any agent's trust score for free, and registering your own agent takes a short SDK integration. Signed audit records support later review. A free tier covers the first steps.
