with DPX() as dpx:
    # Check oracle before settling
    oracle = dpx.oracle_status()
    print(oracle.status, oracle.recommendation)  # STABLE  PROCEED

    # Get a binding quote
    quote = dpx.quote(amount_usd=500_000, has_fx=True, esg_score=75)
    print(f"Net: ${quote.net_amount_usd:,.2f}  Fee: {quote.total_fee_pct:.3f}%")

    # Execute in sandbox (safe default)
    result = dpx.settle(
        amount=500_000,
        source_currency="USD",
        destination_currency="EUR",
        recipient_address="0xYourRecipientAddress",
        sandbox=True,  # set False for live execution
    )
    print(result.status, result.settlement_id)
