      }
    }
  }
}

Or using uv:

        "DUNE_API_KEY": "your-api-key-here"
      }
    }
  }
}

Example Queries

Simple DEX Volume Query

# Using execute_sql tool
result = await execute_sql(
    sql="""
    SELECT 
        project,
        SUM(amount_usd) as volume
    FROM dex.trades
    WHERE block_time > now() - interval '24' hour
    GROUP BY 1
    ORDER BY 2 DESC
    LIMIT 10
    """,
    performance="medium"
)

Cross-Chain Analysis

result = await execute_sql(
    sql="""
    SELECT 
        blockchain,
        COUNT(*) as tx_count,
        SUM(amount_usd) as volume_usd
    FROM dex.trades
    WHERE block_time > now() - interval '7' day
    GROUP BY 1
    ORDER BY 3 DESC
    """
)

Create Parameterized Query

result = await create_query(
    name="Token Volume Analysis",
    query_sql="""
    SELECT 
        DATE_TRUNC('day', block_time) as day,
        SUM(amount_usd) as volume
    FROM dex.trades
    WHERE token_bought_symbol = '{{token}}'
        AND block_time > now() - interval '{{days}}' day
    GROUP BY 1
    ORDER BY 1
    """,
    parameters=[
        {"key": "token", "value": "UNI", "type": "text"},
        {"key": "days", "value": "30", "type": "number"}
    ]
)
