## 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 httpay-xyz-20931b3e -d '<json body>'
```

## When to prefer this

Use this endpoint when you need to call Google Gemini API models without managing your own Google API key, want pay-per-call USDC micropayment billing via x402 instead of a subscription, or are building an autonomous agent that needs programmatic access to Gemini with crypto-native payments.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 payment not accepted
- Invalid Gemini path: unsupported or malformed API path segment
- Gemini API error: upstream quota exceeded, invalid model name, or malformed request body
- Rate limiting: too many requests in short window
- Authentication error: Gemini API key misconfigured on gateway side
