And when you open your browser at <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>, you will that OpenAPI supports this format of query parameter:

However, since the query parameters are declared in the request as
```
http://127.0.0.1:8000/query/mixed-type-params?query=1&foo=bar&foo=baz
```
**FastAPI** greedily adds all the query parameters to every `Query` argument for which it is valid. The above request will be parsed as:
```Python
{
"query": 1,
"string_mapping": {
"query": "1",
"foo": "baz"
},
"mapping_query_int": {
"query": 1
},
"sequence_mapping_queries": {
"query": [
"1"
],
"foo": []
}
}
```
As you can see the `query` parameter is added to every `Query` argument for which it is valid. This is because **FastAPI** does not know which `Query` argument you want to add the `query` parameter to, and `1` validates as both an `int` and a `str`. `List[str]`. `foo` is only added to the `string_mapping` and `sequence_mapping_queries` arguments because it is not a valid `int`.
