Environment / auth
  • A2A_API_KEY
    secret

    A2A TrustGate API key (a2a_...). Optional: without a key the server starts and can guide signup; most tools require a key to call the firewall.

  • A2A_URL

    Base URL of the A2A TrustGate API. Defaults to https://a2ainfrastructure.com.

  • Authorization
    secret

    Bearer token using your A2A TrustGate API key: 'Bearer a2a_...'. Optional — connect keyless to start in onboarding mode and self-provision a tenant in-session.
