Endpoint
POSThttps://quanta-roan.vercel.app/api/service/serp-bing-shopping?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need Bing Shopping-specific product search results with micropayment-per-call billing, ideal for pay-as-you-go agents that don't need a subscription and want to compare prices or discover products across merchants. Prefer over Google Shopping SERP endpoints when Bing Shopping coverage or pricing differences matter to your use case.
