# generate\_feature

Dispatch AI test generation for a feature. Returns immediately with a `requestId`; the pipeline runs in a cloud sandbox for several minutes.

{% hint style="warning" %}
Generation **consumes account credits**. One generation per feature at a time — a second dispatch while one is in flight returns `409 conflict`.
{% endhint %}

## Request

```
POST /api/v1/ops/projects/{project}/features/{feature}/generate
```

| Parameter | In   | Type   | Required | Description                                                        |
| --------- | ---- | ------ | -------- | ------------------------------------------------------------------ |
| `project` | path | string | yes      | The project's public id.                                           |
| `feature` | path | string | yes      | Feature id or name.                                                |
| `siteUrl` | body | string | no       | Test site URL override (defaults to the project's configured URL). |

{% tabs %}
{% tab title="cURL" %}

```bash
curl -X POST -H "Authorization: Bearer $TESTVIBE_API_KEY" \
  -H "Content-Type: application/json" -d '{}' \
  "$TESTVIBE_SERVER/api/v1/ops/projects/$PROJECT/features/12/generate"
```

{% endtab %}

{% tab title="CLI" %}

```bash
testvibe generate "Login Functionality" --watch
```

{% endtab %}

{% tab title="MCP" %}
Tool **`generate_feature`** — `{ "feature": "Login Functionality" }`. Follow with `wait_for_generation`.
{% endtab %}
{% endtabs %}

## Response

`202 Accepted`

```json
{ "requestId": "a1b2c3d4-…", "featureId": 12 }
```

The feature's status flips to `generating`; track progress via [`get_generation_status`](/testvibe-api/api-reference/generation/get_generation_status.md) and land on `generated` or `failed`.

## Errors

| HTTP            | When                                              |
| --------------- | ------------------------------------------------- |
| `404 not_found` | No such feature in this project.                  |
| `409 conflict`  | Already generating, or the dispatch was rejected. |
