Cross-Border Oil Contract & Sanctions Multi-Agent Graph with LangChain and Across AI
Executing crude export mechanisms involving both local and foreign trading entities requires multi-layered legal and international compliance verification. Using LangChain and LangGraph alongside Across AI multi-agent communication networks, build a stateful execution graph that cross-references deal terms against international sanctions, trade embargos, and local banking clearing conditions. The system coordinates three specialized sub-agents: Legal Document Parser, Sanctions Screening Agent, and Financial Settlement Verifier. The graph enforces checkpointing, conditional state transitions, and automatic escalation.
What you are building
Construct a multi-agent LangChain and LangGraph workflow integrated with Across AI for automated crude export compliance audits.
How work is evaluated
Evaluates contract audit graph accuracy against sanctioned counterparty profiles.
Datasets
Public datasets, plus the private datasets you have access to.
How submissions are scored
trade_clearance_check
Ensure clean entity is approved without false flags.
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
audit_precision
Precision score on flagged compliance violations. • target: 0.99 • range: 0-1
