OpenAPI (previously known as Swagger) is the open specification for building APIs (now part of the Linux Foundation).

**FastAPI** is based on **OpenAPI**.

That's what makes it possible to have multiple automatic interactive documentation interfaces, code generation, etc.

OpenAPI has a way to define multiple security "schemes".

plugins {
  kotlin("jvm")
  id("org.jetbrains.dokka")
  id("com.vanniktech.maven.publish.base")
  id("binary-compatibility-validator")
}

project.applyOsgi(
  "Export-Package: okhttp3.logging",
  "Automatic-Module-Name: okhttp3.logging",
  "Bundle-SymbolicName: com.squareup.okhttp3.logging"
)

dependencies {
  "friendsApi"(projects.okhttp)

  testImplementation(libs.junit)

  id("org.jetbrains.dokka")
  id("com.vanniktech.maven.publish.base")
  id("binary-compatibility-validator")
  id("ru.vyarus.animalsniffer")
}

project.applyOsgi(
  "Export-Package: okhttp3.tls",
  "Automatic-Module-Name: okhttp3.tls",
  "Bundle-SymbolicName: com.squareup.okhttp3.tls"
)

dependencies {
  api(libs.squareup.okio)
  "friendsImplementation"(projects.okhttp)
  compileOnly(libs.animalsniffer.annotations)

* **Enxuto**: Minimize duplicação de código. Múltiplos recursos para cada declaração de parâmetro. Menos bugs.
* **Robusto**: Tenha código pronto para produção. E com documentação interativa automática.

├── DurableHandleRequest.java        - Durable handle v1 support
├── DurableHandleV2Request.java      - Durable handle v2 with timeout
└── HandleReconnector.java           - Automatic handle reconnection
```

#### 2.2 Implementation Tasks
- [ ] Implement persistent/durable handle contexts
- [ ] Add handle GUID generation and tracking
- [ ] Implement handle state serialization

You can customize several metadata configurations in your **FastAPI** application.

## Metadata for API { #metadata-for-api }

You can set the following fields that are used in the OpenAPI specification and the automatic API docs UIs:

| Parameter | Type | Description |
|------------|------|-------------|
| `title` | `str` | The title of the API. |

* Esquemas que serán parte del esquema de OpenAPI generado y usados por la <abbr title="User Interfaces">UIs</abbr> de documentación automática.

## Documentación automática

Los JSON Schemas de tus modelos serán parte del esquema OpenAPI generado y se mostrarán en la documentación API interactiva:

* **Easy**: Designed to be easy to use and learn. Less time reading docs.
* **Short**: Minimize code duplication. Multiple features from each parameter declaration. Fewer bugs.
* **Robust**: Get production-ready code. With automatic interactive documentation.

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,
    APIKeyHeader,

 */

import java.util.Iterator;

/**
 * An iterator that implements AutoCloseable to allow resource cleanup.
 * This interface combines Iterator functionality with automatic resource management.
 *
 * @param <T> the type of elements returned by this iterator

public interface CloseableIterator<T> extends Iterator<T>, AutoCloseable {
