## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability fastaf-google-ai-mode-search-96aad0d7
```

Example prompt: Search Google AI Mode for 'What are the health benefits of intermittent fasting?' and give me the answer with all the cited sources.

## When to prefer this

Choose this endpoint when you need Google's AI Mode synthesized answer (not just a list of blue links) for a question, returned as structured JSON with cited sources. Ideal for agents that need authoritative AI-summarized information with traceable references rather than raw search result pages. Prefer over general web scraping when you specifically want Google's AI-generated overview format.

## Known failure modes

- Query returns empty AI Mode answer — not charged, returns empty text_blocks array
- Invalid or unsupported query format results in error response
- Combining location and uule parameters simultaneously causes a validation error
- Rate limiting or upstream Google availability issues may result in failed requests — failed requests are never settled
- Invalid country or language codes may produce unexpected or default-locale results

## How this service works

AI answer and web research API for AI agents: Google AI Mode responses as JSON text blocks and source references. Supports natural-language search questions with country and language targeting for research summaries; source links may be Google redirect paths. Provided by FastAF Google AI Answers. Price: $0.010000 USDC per successful call.

## Output

A JSON array of text_blocks, each containing a paragraph type, a snippet of the AI-generated answer text, and an array of cited source links (URLs) that back up that portion of the answer. Empty answers (no AI response generated) are not charged.
