Quick start

from aigentsy_langgraph import register_node, proof_pack_node, go_node, verify_node

# Use as LangGraph nodes in a StateGraph
from langgraph.graph import StateGraph

graph = StateGraph(dict)
graph.add_node("register", register_node)
graph.add_node("proof", proof_pack_node)
graph.add_node("go", go_node)
graph.add_node("verify", verify_node)
graph.add_edge("register", "proof")
graph.add_edge("proof", "go")
graph.add_edge("go", "verify")
app = graph.compile()

result = await app.ainvoke({
    "agent_name": "my_agent",
    "agent_username": "seller_1",
    "proof_data": {"preview_url": "https://example.com/work.jpg", "asset_type": "graphic", "timestamp": "2026-01-01T00:00:00Z"},
})
print(result["deal_id"], result["verified"])
