## 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 openweb-ninja-google-ai-mode-answers-api-61c20ab0 -d '<json body>'
```

Example prompt: What does Google AI Mode say about the best programming languages for machine learning in 2025? Search in English for US results.

## When to prefer this

Choose this endpoint when you need programmatic access to Google's AI Mode search answers without managing API keys or subscriptions. It is ideal for agents that need AI-synthesized summaries from Google's search AI rather than raw SERP links, and when you want pay-per-call pricing via x402/USDC with no account setup. Prefer over traditional SERP APIs when the goal is a synthesized AI answer rather than a list of links.

## Known failure modes

- Empty or malformed prompt returns an error or empty answer
- Invalid gl/hl locale codes may return unexpected language results
- Rate or payment failure if USDC balance is insufficient (x402 payment required per call)
- Google AI Mode may not return an AI answer for all query types, resulting in empty response
- Session token issues may cause authentication or session continuity failures
- Timeout if Google's AI Mode takes too long to respond
