## 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 singit-ask-gemini-3-8-flash-chat-completions-735bea39 -d '<json body>'
```

Example prompt: Ask Gemini 3.8 Flash: given this conversation history — system: 'You are a concise travel advisor', user: 'What are the top 3 things to do in Kyoto in spring?' — give me a response in at most 800 tokens.

## When to prefer this

Choose this endpoint when your agent needs Google Gemini 3.8 Flash specifically — prioritizing low cost and low latency over maximum capability — without managing a Google API key or billing account. Ideal for high-volume inference pipelines, latency-sensitive tasks, or when you want OpenAI SDK compatibility with a Gemini backend. Prefer alternatives like GPT-5.5 or Claude for tasks requiring top-tier reasoning, or SingIt's image/speech endpoints for non-text modalities.

## Known failure modes

- Message content exceeding 24,000 characters total causes rejection
- max_tokens above 1,200 is not accepted
- Fewer than 1 message in the conversation triggers a validation error
- Payment failure or insufficient USDC balance via x402 blocks the call
- Model ID not available at /v1/models returns an error
