SerpApi Google Shopping API vs Google Shopping for AI agents
SerpApi Google Shopping API is a paid third-party API that scrapes Google Shopping results and returns them as JSON. Google's commerce developer tools are for sellers: Merchant API manages a merchant's own Merchant Center products, and UCP on Google lets merchants sell inside AI Mode in Search and Gemini.
The short answer
- SerpApi Google Shopping API: Seeing what Google Shopping shows for a query, across many stores, without a seller account.
- Google Shopping: Merchants who want their products shown and sold in Google Shopping, AI Mode and Gemini, not developers who want to search products.
Side by side
| SerpApi Google Shopping API | Google Shopping | |
|---|---|---|
| Searches | Google Shopping results for a query, localised by country (gl) and location. | – |
| Returns | Position, title, price, rating, source (store) and a link per result, plus a token for a detailed product page. | – |
| Before the first call | A SerpApi account and API key. | Merchant API needs a Merchant Center account and a Google Cloud project; UCP on Google is joined through a waitlist. |
| Free | Free plan: 250 searches a month; only successful searches count. | – |
| Paid | Starter plan $25 a month for 1,000 searches. | – |
| Acting on a result | Each result links to its Google Shopping page and names the store; no checkout. | Nothing for outside agents; UCP checkout happens inside Google's own AI Mode and Gemini. |
| Limits on keeping or showing results | SerpApi keeps search data for 31 days, or not at all with its ZeroTrace mode (Enterprise only); its legal cover is for collecting the data, not for how you use it. | – |
| Coverage | Any country Google Shopping serves, chosen with the gl country code. | – |
| MCP server | Official hosted MCP server at mcp.serpapi.com (needs a SerpApi API key). | – |
