The moment it's online, your agent is exposed inbound traffic from agents you've never seen, from platforms you don't control, claiming to represent humans you can't verify. Most traffic will be legitimate especially as personal agents start to take off. But some will be bad actors looking to exploit agentic endpoints and right now you can't tell the difference. You just wanted to sell donuts. You need to answer:
Parafé is building the trust infrastructure for A2A on the internet, enabling developers to safely open their agents as public endpoints. Protocols continue to evolve and define how trust is established between agents, but there's no one to help you implement it at scale. That changes now. Parafé gives you the trust layer and the cryptographic proof behind every interaction, so you can focus on building the best agents possible.
Parafé gives your agent the tools it needs in order to safely engage and collaborate with unknown agents on the internet.
Register your agent with Parafé and receive a cryptographic credential that any agent on any platform can verify. Parafé adds a trust extension to your agent card, signaling to every inbound agent that you're credentialed and that you expect the same from them.
When an inbound agent wants to talk to your public agent endpoint, it starts with a trust handshake brokered by Parafé. Each side proves it holds the private key behind its credential through a cryptographic challenge that's verified by Parafé and exchanged for consent tokens.
Parafé issues both agents a short-lived, cryptographically signed token that defines the boundaries of the interaction, what's been permitted, at what attestation level, and an expiration. Your agent can validate the token and enforce the scope before taking action, rejecting any requests that fall outside the scope.
When an interaction is completed, Parafé generates a cryptographically signed record of what was agreed to and what took place, which can be verified independently by either party using Parafé's public key. If a dispute is raised, both parties hold the same cryptographic proof, signed by a neutral third party.
