# Run ML-Assisted Labeling

You can label a project using existing model that is provided by the app or your own model. Currently, this API only support the custom API, i.e. your own model. Also, this mutation is asynchronous so the response only returns the job information.

* Mutation: [autoLabelTokenBasedProject](https://docs.datasaur.ai/#mutation-autoLabelTokenBasedProject)
* Input: [AutoLabelTokenBasedProjectInput](https://docs.datasaur.ai/#definition-AutoLabelTokenBasedProjectInput)
* Response: [Job](https://docs.datasaur.ai/#definition-Job)

### **Example Request via cURL**

```javascript
curl --location --request POST 'https://app.datasaur.ai/graphql' \
--header 'Authorization: Bearer <access_token>' \
--header 'Content-Type: application/json' \
--data-raw '{"operationName":"AutoLabelTokenBasedProjectMutation","variables":{"input":{"labelerEmail":"demo@datasaur.ai","options":{"numberOfFilesPerRequest":0,"serviceProvider":"CUSTOM"},"projectId":"HvdyIL2iwZn","targetAPI":{"endpoint":"https://custom-model.api.com/predict","secretKey":"secret"}}},"query":"mutation AutoLabelTokenBasedProjectMutation($input: AutoLabelTokenBasedProjectInput!) {  result: autoLabelTokenBasedProject(input: $input) {    id  status  progress  }}"}'
```

Below is the more readable version of request body from cURL command above.

```javascript
{
    "operationName": "AutoLabelTokenBasedProject",
    "variables": {
        "input": {
            "labelerEmail": "demo@datasaur.ai",
            "options": {
                "numberOfFilesPerRequest": 0,
                "serviceProvider": "CUSTOM"
            },
            "projectId": "HvdyIL2iwZn",
            "targetAPI": {
                "endpoint": "https://custom-model.api.com/predict",
                "secretKey": "secret"
            }
        }
    },
    "query": "mutation AutoLabelTokenBasedProjectMutation($input: AutoLabelTokenBasedProjectInput!) {  result: autoLabelTokenBasedProject(input: $input) {    id  status  progress  }}"
}
```

* **operationName**: you can fill any alphanumeric string in as the operationName. `AutoLabelTokenBasedProjectMutation` is fine as a default. Refer [this page](https://graphql.org/learn/queries/#operation-name) to organize operationName properly.
* **variables**
  * **input:** see the explanation of each variables [here](https://docs.datasaur.ai/exporttextprojectinput.doc). See the additional information for [AutoLabelProjectOptionsInput](https://docs.datasaur.ai/#definition-AutoLabelProjectOptionsInput) below.
    * Again, currently we only support CUSTOM `serviceProvider`
    * If the `numberOfFilesPerRequest` is 0, then it will request all lines in a document. If it's more than 0, the backend will batch the request based on how many lines for each request.
* **query:** Copy it from cURL example.

### Example Response

Here is the response when you execute the cURL command above.
