# Realizar solicitudes

La forma más fácil de empezar es enviar una consulta simple sin opciones personalizadas. Añadiremos todos los encabezados estándar de nuestro lado, elegiremos el proxy más rápido y te entregaremos el cuerpo de la respuesta.

```bash
curl -k -x https://unblock.oxylabs.io:60000 \
-U 'USERNAME:PASSWORD' \
'https://ip.oxylabs.io/location'
```

{% hint style="info" %}
Si observas tasas de éxito bajas u obtienes contenido vacío, intenta añadir un `"x-oxylabs-render: html"` encabezado con tu solicitud. Puedes encontrar más información sobre el renderizado de JavaScript [**aquí**](/products/es/web-unblocker/custom-browser-instructions/javascript-rendering.md).
{% endhint %}

Para utilizar funcionalidades adicionales de [**Web Unblocker**](https://github.com/oxylabs/web-unblocker), como configurar la ubicación del proxy o reutilizar la misma IP para unas pocas solicitudes consecutivas, envía encabezados adicionales con la solicitud.

{% hint style="info" %}
Para un bloqueo óptimo de sitios web, Web Unblocker emplea cookies, encabezados y sesiones predefinidos. Por favor, **abstente de enviar parámetros personalizados que se usan comúnmente para mejorar la accesibilidad de los datos**, ya que pueden interferir con la capacidad de Web Unblocker para obtener datos de calidad.
{% endhint %}

Aquí está la lista completa de funcionalidades y encabezados compatibles:

### Funcionalidades adicionales

| Parámetro                           | Descripción                                                                                                                                                                                                                                         | Enlace para leer más                                                                                            |
| ----------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------- |
| `X-Oxylabs-Session-Id`              | Si deseas reutilizar la misma IP para varias solicitudes, añade un ID de sesión que puede ser una cadena aleatoria de caracteres.                                                                                                                   | [**Sesión**](/products/es/web-unblocker/making-requests/session.md)                                             |
| `X-Oxylabs-Geo-Location`            | Para usar una dirección IP de una ubicación específica, especifica un país o una ciudad, por ejemplo, Alemania. Puedes encontrar los valores de geolocalización compatibles [**aquí**](/products/es/web-unblocker/making-requests/geo-location.md). | [**Geolocalización**](/products/es/web-unblocker/making-requests/geo-location.md)                               |
| Encabezados                         | Si quieres enviar encabezados personalizados, usa `x-oxylabs-force-headers: 1` encabezado al enviar tu solicitud.                                                                                                                                   | [**Encabezados**](/products/es/web-unblocker/making-requests/headers.md)                                        |
| Cookies                             | Puedes añadir tus cookies, por ejemplo, `Cookie: NID=1234567890`, a tus solicitudes.                                                                                                                                                                | [**Cookies**](/products/es/web-unblocker/making-requests/headers.md)                                            |
| `X-Oxylabs-Successful-Status-Codes` | Si tu sitio objetivo devuelve un código de estado no estándar con una respuesta exitosa, puedes enviar el código de estado de la respuesta y nuestro sistema no reintentará la solicitud.                                                           | [**Código de estado personalizado**](/products/es/web-unblocker/making-requests/custom-status-code.md)          |
| `X-Oxylabs-Render`                  | Si quieres renderizar JavaScript, usa `html` para obtener un HTML renderizado o `png` para obtener una captura de pantalla de la página.                                                                                                            | [**Renderizado de JavaScript**](/products/es/web-unblocker/custom-browser-instructions/javascript-rendering.md) |
