+# Up API
+
+A convenient and easy to use wrapper for the [UP Bank API](https://developer.up.com.au).
+
+## Example
+
+The following example shows the calculation of the sum of all transactions after a given date.
+
+```
+use up_api::Client;
+use up_api::transactions::ListTransactionsOptions;
+
+#[tokio::main]
+async fn main() {
+    let token = std::env::var("UP_ACCESS_TOKEN").unwrap();
+    let client = Client::new(token.to_string());
+
+    let mut options = ListTransactionsOptions::default();
+    options.filter_since("2020-01-01T01:02:03+10:00".to_string());
+
+    let transactions = client.list_transactions().unwrap();
+
+    let total : f32 =
+        transactions
+        .data
+        .into_iter()
+        .map(|t| t.attributes.amount.value)
+        .map(|v| v.parse::<f32>())
+        .sum();
+
+    println!("{}", total);
+}
+```
