# Get a model version

`GET /models/{model_owner}/{model_name}/versions/{version_id}`

Example cURL request:

```console
curl -s \
  -H "Authorization: Bearer $REPLICATE_API_TOKEN" \
  https://api.replicate.com/v1/models/replicate/hello-world/versions/5c7d5dc6dd8bf75c1acaa8565735e7986bc5b66206b55cca93cb72c9bf15ccaa
```

The response will be the version object:

```json
{
  "id": "5c7d5dc6dd8bf75c1acaa8565735e7986bc5b66206b55cca93cb72c9bf15ccaa",
  "created_at": "2022-04-26T19:29:04.418669Z",
  "cog_version": "0.3.0",
  "openapi_schema": {...}
}
```

Every model describes its inputs and outputs with [OpenAPI Schema Objects](https://spec.openapis.org/oas/latest.html#schemaObject) in the `openapi_schema` property.

The `openapi_schema.components.schemas.Input` property for the [replicate/hello-world](https://replicate.com/replicate/hello-world) model looks like this:

```json
{
  "type": "object",
  "title": "Input",
  "required": [
    "text"
  ],
  "properties": {
    "text": {
      "x-order": 0,
      "type": "string",
      "title": "Text",
      "description": "Text to prefix with 'hello '"
    }
  }
}
```

The `openapi_schema.components.schemas.Output` property for the [replicate/hello-world](https://replicate.com/replicate/hello-world) model looks like this:

```json
{
  "type": "string",
  "title": "Output"
}
```
