Agent-to-Agent (A2A) SDK is now available with support for Agentic Profiles: Globally unique user and business scoped agent identities, and universal authentication

Google has released Python and Java SDKs for A2A, but only has some example code for Javascript.

I took this opportunity to repackage Google's example code, refactor and clean up the rough code, and make it available as open source. I also filled in a big gap that is needed for the Agentic Economy: the ability of agents to establish trust though user and business scoped identity and universal authentication.

The Javascript/Typescript SDK is available at https://github.com/agentic-profile/agentic-profile-a2a

The SDK leverages three other libraries:

• A2A Client - Typescript browser or server client with Agentic Profile support
• A2A Service - Makes it easy to add A2A agents to existing Node Express servers. Supports multi-agent and multi-tenancy
• Agentic Profile Auth - Leverages W3C DID documents and IETF JSON Web Tokens to establish user and business scoped agent identities and universal authentication
