But you still need to define what is the dependable, the callable that you pass as a parameter to `Depends()` or `Security()`.

There are multiple tools that you can use to create those dependables, and they get integrated into OpenAPI so they are shown in the automatic docs UI, they can be used by automatically generated clients and SDKs, etc.

You can import them from `fastapi.security`:

```python
from fastapi.security import (
    APIKeyCookie,

/// tip | Tipp

Verwenden Sie für neuen Code, und wann immer möglich, `Annotated`, wie oben erklärt. Es gibt mehrere Vorteile (unten erläutert) und keine Nachteile. 🍰

So würden Sie `Query()` als Defaultwert Ihres Funktionsparameters verwenden, den Parameter `max_length` auf 50 gesetzt:

    conflict with the copy of ListenableFuture in guava itself. If users are
    using an older version of Guava or a build system other than Gradle, they
    may see class conflicts. If so, they can solve them by manually excluding
    the listenablefuture artifact or manually forcing their build systems to
    use 9999.0-....

In this case, **FastAPI** will notice that there is more than one body parameter in the function (there are two parameters that are Pydantic models).

So, it will then use the parameter names as keys (field names) in the body, and expect a body like:

```JSON
{
    "item": {
        "name": "Foo",
        "description": "The pretender",
        "price": 42.0,

  public void testReserializeSubList() {
    SerializableTester.reserializeAndAssert(getList().subList(0, 2));
  }

  /**
   * Returns the {@link Method} instance for {@link #testSubList_originalListSetAffectsSubList()} so
   * that tests of {@link CopyOnWriteArrayList} can suppress them with {@code
   * FeatureSpecificTestSuiteBuilder.suppressing()} until <a
   * href="https://bugs.openjdk.org/browse/JDK-6570631">JDK-6570631</a> is fixed.
   */

   * than a one-character array containing the character itself. This enables the escaping algorithm
   * to perform more efficiently.
   *
   * <p>An escaper is expected to be able to deal with any {@code char} value, so this method should
   * not throw any exceptions.
   *
   * @param c the character to escape if necessary
   * @return the replacement characters, or {@code null} if no escaping was needed
