Bing images search in Angular

I want to implement Bing Images API in my Angular app. For now I will do it client side. But I get a 404 answer when making a GET request.

@Injectable()
export class BingService {
  private endpoint =
    "https://api.bing.microsoft.com/bing/v7.0/images/search";
  private token = "9dc015a3a15c45abb05f88bcea641c2d";

  constructor(private httpClient: HttpClient) {}

  getImage(term: string) {
    const httpParams = new HttpParams({
      fromObject: {
        q: term,
        count: "1"
      }
    });

    const httpHeaders = new HttpHeaders({
      "Ocp-Apim-Subscription-Key": this.token
    });
    httpHeaders.set("Ocp-Apim-Subscription-Key", this.token);

    return this.httpClient.get(this.endpoint, {
      params: httpParams,
      headers: httpHeaders
    });
  }
}

Here is a stackblitz with the issue
