Y porque el esquema generado es del estándar [OpenAPI](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md), hay muchas herramientas compatibles.

Debido a esto, el propio **FastAPI** proporciona una documentación de API alternativa (usando ReDoc), a la cual puedes acceder en [http://127.0.0.1:8000/redoc](http://127.0.0.1:8000/redoc):

**No está soportado** por Pydantic tener un modelo de Pydantic v2 con sus propios campos definidos como modelos de Pydantic v1 o viceversa.

 * <p>The job supports selective crawling by specifying configuration IDs for different
 * types of crawlers (web, file, data). It manages the crawler process lifecycle,
 * handles timeout scenarios, and ensures proper cleanup of resources.</p>

 * <p>Key features:</p>
 * <ul>
 *   <li>Concurrent crawler process management with configurable limits</li>
 *   <li>Selective crawling based on configuration IDs</li>
