# Ejemplos

## Sandbox para QA

Antes de levantar tu propia app, puedes registrar estas URLs sandbox de Videsk como `iframe.url` para validar que tu cuenta, segmento y permisos están bien configurados. Te muestran en pantalla lo que recibe la app, así que sirven para depurar context, scopes y plantillas sin construir nada.

| URL                                                 | Para qué sirve                                                                                                                                                                                                              |
| --------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `https://sdbx.videsk.io/iframes/broker/postmessage` | Verifica el handshake del [broker](/es-developers/apps/broker.md): muestra el `videsk:init` recibido y el `context` resuelto. Es la versión hospedada del ejemplo [App mínima](/es-developers/apps/ejemplos/app-minima.md). |
| `https://sdbx.videsk.io/iframes/query-params`       | Muestra los query params resueltos por Handlebars en la URL. Útil para validar [Plantillas y contexto](/es-developers/apps/plantillas.md) sin un broker.                                                                    |

{% hint style="info" %}
Cuándo conviene usarlos:

* Validar que tu app aparece en el launcher con la configuración correcta.
* Confirmar que `contextScopes` está entregando los bloques que esperas.
* Probar que tu plantilla Handlebars resuelve los valores correctos.
* Reproducir un bug antes de tocar código de tu lado.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.videsk.io/es-developers/apps/ejemplos.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
