   Answer with [1][2][3] source links

When an AI tool calls google_search, GSearch returns a grounded answer with inline citations:

The current time in Sao Paulo is 08:13 AM.[1][2]
Sao Paulo observes Brasilia Time (BRT), UTC-3.[3]

Sources:
[1] Time in Sao Paulo (https://...)
[2] World Clock (https://...)
[3] Time Zone Info (https://...)

GSearch uses the same Google Search grounding API as Gemini CLI. Free with any Google account. No API key, no credit card, no billing setup.

Rate limits are generous for normal usage. The
