class Brand extends JsonResource
{
	/**
     * Indicates if the resource's collection keys should be preserved.
     *
     * @var bool
     */
    public $preserveKeys = true;
    /**
     * The "data" wrapper that should be applied.
     *
     * @var string
     */
    public static $wrap = 'brands';
    /**
     * Transform the resource into an array.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function toArray($request)
    {
        return [
            'brand_id' => $this->brand_id,
            'brand_name' => $this->brand_name,
        	'brand_logo' => asset('storage/'.$this->brand_logo),
        	'cars'=>CarResources::collection($this->whenLoaded('cars')),
            'created_at'=>$this->created_at,
            'updated_at'=>$this->updated_at
        ];
    }
     public function with($request){
        return[
            'status'=>'success',
        ];
    }
}

collection class

class BrandCollection extends ResourceCollection {
	
	/**
	 * The resource that this resource collects.
	 *
	 * @var string
	 */
	public $collects = Brand::class;
	/**
	 * Transform the resource collection into an array.
	 *
	 * @param \Illuminate\Http\Request $request
	 * @return array
	 */
	public function toArray($request) {
		return ['brands' => $this->collection];		
	}
}

API route
Route::get('/brand/search',[App\Http\Controllers\BrandController::class,'searchForBrand'])->name('searchForBrand');

the same code out of the controller working just fine

 Route::get('/elq',function(Request $request){
     $brand_name = $request->query('brand_name');
     $brands = App\Models\Brand::where('brand_name','like','%'.$brand_name.'%')->get();
     return new App\Http\Resources\BrandCollection($brands);
	 });
