## 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 llm-proxy-gemini-pay-per-call-chat-34d33d4a
```

Example prompt: Send this prompt to a Gemini LLM and give me the response — I'll pay per call in USDC: 'Summarize the key differences between REST and GraphQL in three bullet points.'

## When to prefer this

Choose this endpoint when you need pay-per-call Gemini LLM inference without a subscription, especially in agentic workflows where usage is sporadic or unpredictable. It is ideal for Web3-native apps that already use x402/USDC micropayments on Base, or for prototyping where a flat per-request cost is preferable to committed API quotas.

## Known failure modes

- Payment not received or insufficient USDC balance — request rejected with 402 Payment Required
- Invalid or missing schema/prompt parameter — returns 400 Bad Request
- Gemini model unavailable or rate-limited upstream — returns 503 or timeout
- x402 facilitator network issue causing payment verification failure
- Model tier mismatch or unsupported tier requested
