# Crear una colección

`POST https://ai.inovacc.dev/v1/collections`

Crea una colección de conocimiento, en el modo que decide lo que puede hacer.

## Parámetros del cuerpo

- `mode` ("download" | "cloud" | "local_vectors"), obligatorio: `download`: procesa archivos y descarga el resultado. `cloud`: además consulta, conversa y analiza. `local_vectors`: conserva solo los vectores de los fragmentos que tú generas. Fijo durante toda la vida de la colección.

## Encabezados

- `Authorization` (string), obligatorio: Bearer <clave de API>
- `X-Operation-Id` (string), obligatorio: un id único que tú eliges, en toda llamada excepto GET
- `Content-Type` (string), obligatorio: application/json, en una llamada con cuerpo

## Solicitud
