Step 6. Register your agent cards

Once the AI agents are validated, you can register your agent card URLs with your enterprise agent registry. This step is optional.
After you do this, any A2A-compatible client can discover and call them using the agent card URL.
For more information about registering your agent cards, see the documentation for your registry.
