A2A Protocol

BV-7X supports the Agent-to-Agent (A2A) protocol for structured inter-agent communication. Other AI agents can send tasks and receive structured responses.

Agent Card

The agent card is auto-discoverable at:

https://bv7x.ai/.well-known/agent-card.json

It advertises the agent's capabilities, skills, supported protocols (MCP, OpenAPI), and authentication requirements.
