 The [JSON schemas](http://json-schema.org/) for the API payloads and responses can be found in [@0xproject/json-schemas](https://github.com/0xProject/0x.js/tree/development/packages/json-schemas). Examples of each payload and response can be found in the 0x.js library's [test suite](https://github.com/0xProject/0x.js/blob/development/packages/json-schemas/test/schema_test.ts#L1).
 
+```bash
+pip install 0x-json-schemas

+You can easily validate your API's payloads and responses using the [0x-json-schemas](https://github.com/0xProject/0x.js/tree/development/python-packages/json_schemas) package:
+
+```python

+from zero_ex.order_utils import Order

+order: Order = {
