Les réponses générées au format OpenAPI pour cette *opération de chemin* seront :

```JSON hl_lines="3-12"
{
    "responses": {
        "404": {

            * **FastAPI** adds a reference here to the global JSON Schemas in another place in your OpenAPI instead of including it directly. This way, other applications and clients can use those JSON Schemas directly, provide better code generation tools, etc.

The generated responses in the OpenAPI for this *path operation* will be:

```JSON hl_lines="3-12"

The same way, there are many compatible tools. Including code generation tools for many languages.

De la même façon, il existe bien d'autres outils compatibles, y compris des outils de génération de code
pour de nombreux langages.

## Pydantic

Toute la validation de données est effectué en arrière-plan avec <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a>,

* Designed around these standards, after a meticulous study. Instead of an afterthought layer on top.
* This also allows using automatic **client code generation** in many languages.

### Automatic docs { #automatic-docs }

Interactive API documentation and exploration web user interfaces. As the framework is based on OpenAPI, there are multiple options, 2 included by default.

        Crawler.Options options = new Crawler.Options();
        // Don't set sessionId to test default generation

        // Mock the container setup to avoid actual initialization
        try {
            // The process method will generate a default sessionId if not provided

        metrics.put("rotationTimeLimit", keyRotationTimeLimit);
        return metrics;
