Add cryptographic authorization to AI agents in 5 minutes

You have AI agents calling each other. You're using API keys or mTLS. You're worried it's not enough. API keys authenticate. They don't authorize. They don't scope. They don't audit delegation chains. Here's how to add all four in under 5 minutes using Codios — an A2A security layer built on signed capability contracts. What you'll build Two agents with cryptographic identities (Ed25519 keypairs) A signed contract granting specific permissions A protected API endpoint that verifies contracts off
