How does it work for App Platform deployment here? Since you don't know the URL prior to the deployment.

base_url now reads from the A2A_BASE_URL environment variable at server startup, falling back to http://localhost:8000 for local development. On App Platform, set A2A_BASE_URL to your app's public URL. The example docstring has been updated to document this.

Wrap any @entrypoint agent as an A2A v0.3.0 server with a single call to create_a2a_server(). Implements message/send, tasks/get, tasks/cancel and agent discovery via /.well-known/agent-card.json. - Hexagonal architecture: domain validation/transformation, adapters, infrastructure - Text-only MVP; streaming, push notifications, and authenticated extended cards explicitly disabled via AgentCard capability flags - base_url reads from A2A_BASE_URL env var for deployment flexibility - 45 tests (unit + integration), including cancel-race coverage - README documentation with protocol flow and deployment guide - New optional dependency: pip install gradient-adk[a2a] Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
