1. fetch_agent_card("https://agent.example.com")
   → see agent costs $0.01, accepts MPP on Algorand

2. send_a2a_message(agent_url, "What is the price of ALGO?")
   → payment_required: true, challenge_headers: {WWW-Authenticate: ...}

3. generate_mpp_challenge(...)   ← use tool #6
   → user pays on-chain

4. send_a2a_message(agent_url, text, payment_proof="<proof>")
