CrewAI Integration

crewai-a2a-settlement bridges CrewAI multi-agent orchestration with the A2A Settlement Exchange.

pip install crewai-a2a-settlement

Quick Start​

from crewai_a2a_settlement import A2AConfig, A2ASettlementClient

config = A2AConfig(api_key="your-sandbox-key")
client = A2ASettlementClient.initialize(config)

# Register agents
payer = client.register_agent("Orchestrator", ["orchestrate"])
payee = client.register_agent("Scraper", ["web_scraping"])

# Escrow → execute → release/cancel
receipt = client.escrow(
    payer_address=payer,
    payee_address=payee,
    amount=5.0,
    task_id="scrape-task-001",
    description="Scrape product data from example.com",
)

# On success:
result = client.release(receipt.escrow_id)

# Or on failure:
# result = client.cancel(receipt.escrow_id, reason="Scraper timed out")
