How to send a request to consume an api?

I am trying to consume the apimedic api.

The following is my ApiMedicService.php

  <?php

  namespace App\Services;

  use GuzzleHttp\Client;

 class ApiMedicService
 {
     protected $client;
     protected $apiKey;

     public function __construct($apiKey)
     {
         $this->client = new Client([
            'base_uri' => 'https://sandbox-healthservice.priaid.ch/',
            'timeout' => 10,
         ]);

        $this->apiKey = $apiKey;
     }

     public function getSymptoms()
     {
         $response = $this->client->get('symptoms', [
             'query' => [
                 'token' => $this->apiKey,
                 'language' => 'en-gb'
             ],
         ]);

         return json_decode($response->getBody(), true);
     }


     public function getDiagnosis($symptoms, $gender, $birth_date, $token)
     {
         $query = http_build_query([
             'symptoms' => $symptoms,
             'token' => $this->apiKey,
             'gender' => $gender,
             'year_of_birth' => $birth_date,
         ]);

         $url = 'diagnosis?' . $query;

         $response = $this->client->get($url);

          return json_decode($response->getBody(), true);
      }
  }

And this is my controller method to getDiagnosis in SymptomsController.php

public function getDiagnosis(Request $request)
    {
        $this->validate($request, [
           'symptoms' => 'required|array',
            'symptoms.*' => 'numeric',
        ]);

    
        $symptoms = $request->input('symptoms');
        $user = Auth::user();
        $gender = $user->gender;
        $birth_date = $user->birth_date;
        $token = config('APIMEDIC_API_KEY');

        $diagnosis = $this->apiMedicService->getDiagnosis($symptoms, $gender, $birth_date, $token);

        return response()->json($diagnosis);
    }

With the following route:

  Route::get('/diagnosis', [SymptomsController::class, 'getDiagnosis'])->middleware('auth');

I am trying to send a request to:

   https://sandbox-healthservice.priaid.ch/diagnosis?symptoms=[10]&gender=female&   year_of_birth=2000&token=<APIMEDIC_API_KEY>

So i want to get the gender and year_of_birth from the propertys gender and birth_date of the logged in user. The APIMEDIC_API_KEY i get it from api key in the env file

But for some reasons when i hit a GET request to http://localhost:8000/api/diagnosis i get symptoms are missing Why is this happening?
