How to add multiple Where conditions on array

"pricing": {
	"services": [{
	"service":"image-retouching",
	"price": [
	{
		"country": "us",
		"rate": "1.50"
	}],}]
}

Considering above JSON I am not able to put two ‘Where’ conditions i.e. Rate required for service = “image-retouching” and for country “us”.

I tried

json.data.pricing.services.where('service','image-retouching','==').values('price').where('country','us','==').values('rate')
