A Google Search API for AI agents.
Not from Google's own JSON API, if you are new. As of October 2026 Google says its Custom Search JSON API is closed to new customers, and existing customers have until 1 January 2027 to move to something else. An agent can still read Google web, news, image and shopping results as JSON, priced per page or per row.

What Google points to instead
Google's overview names Vertex AI Search as the alternative for searching up to 50 domains, and asks you to contact it if your use needs full web search. The older Site Restricted JSON API stopped serving traffic on 8 January 2025.
If your agent searches your own sites or documents, Google's enterprise search products are the right tool. If it needs to see what Google shows anyone for a query, a results API is the practical route.

Priced per record, from $0.00009 per record. A web search is billed per page of about ten results. Quote it first with estimateOnly.

Try it in a minute. $0.10 free.
The playground runs any endpoint by hand: pick a platform and what you want from it, fill a short form named in plain words (or press Use sample input), see the free quote on the Run button, run it, then read the answer as a table or JSON and download it as CSV or JSON. The same call is written out as cURL, Python and Node while you type.
Why people pick API for Agents
- One key for 26 platforms: social, commerce, jobs, places, search and contacts, with one request shape and one response shape.
- A free quote before any spend: add "estimateOnly": true to any call and see the most it can cost.
- Pay per record in US dollars. No subscription, nothing expires, top-ups from $5.
- $0.10 free to try, no card. An AI agent can sign itself up in one request; a person claims it later.
- Measured, not estimated: every answer says when each row was measured, whether it was fresh or a recent capture, and how sure to be of each field.
- Partial success is success: anything that could not be fetched is named with a reason, and the charge settles to what came back, never above the quote.
- Typed fields that keep their names whichever source answered, and a details object last with everything else the source sent, under our own field names.
- Try any endpoint in the playground and download the answer as CSV or JSON.
