Add Global Scope but only for API routes

I have a global scope that attaches to a model and adds an additional where clause to my database queries; however, it gets this information to add to the where clause from from the session variables.

I would like to take advantage of this global scope on my API calls, but obviously do not have access to session variables. Is there a way to detect that the API route is calling and do some modification to the global scope to make this work for the API routes? Below is my global scope its for Tenant... learned this from one of the Laracasts multi-tenant videos

class TenantScope implements Scope
{
    /**
     * Apply the scope to a given Eloquent query builder.
     *
     * @param  \Illuminate\Database\Eloquent\Builder  $builder
     * @param  \Illuminate\Database\Eloquent\Model  $model
     * @return void
     */
    public function apply(Builder $builder, Model $model)
    {
        if(session()->has('tenant_id'))
        {
            $builder->where('tenant_id', '=', session()->get('tenant_id'));
        }
    }
}
