## 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-gemini-chat-x402-6725d686 -d '<json body>'
```

Example prompt: Can you ask Google Gemini to explain the pros and cons of microservices architecture in plain language, and return the answer in markdown format?

## When to prefer this

Choose this endpoint when you need to query Google Gemini specifically without setting up a Google Cloud account or managing API keys, and you want simple per-call USDC micropayments via x402. Ideal for agents that need occasional Gemini inference on-demand without subscription overhead, or when comparing Gemini responses alongside other AI providers available on the same OpenWeb Ninja platform.

## Known failure modes

- Payment not received or insufficient USDC balance causes 402 response
- Invalid or malformed message body returns 400 error
- Stale or invalid conversation_id may reset context or return error
- Gemini API upstream outage causes 5xx error
- Missing required 'message' field causes validation error
