## Call Gemini 3.1 Flash Lite from code

The same model, from an agent or from your own code. Keys stay in your FlyMy.AI account.

### From an agent, through the MCP

The agent calls `get_model_schema`, then `run_model` with:

```
{
  "endpoint_id": "flymyai/google-gemini-31-flash-lite-preview",
  "input": {
    "prompt": "Explain in two sentences what an MCP server is."
  }
}
```

### From your code, over HTTP

Form fields, not JSON; files go as uploads or public URLs. Text models answer on the streaming route.

```
curl -X POST https://api.flymy.ai/api/v1/flymyai/google-gemini-31-flash-lite-preview/predict/stream/ \
  -H "X-API-KEY: $FLYMYAI_API_KEY" \
  -F 'prompt=Explain in two sentences what an MCP server is.'
```

### With the OpenAI SDK

Gemini 3.1 Flash Lite also answers the OpenAI Chat Completions protocol.

client = OpenAI(base_url="https://api.flymy.ai/api/v1/flymyai/google-gemini-31-flash-lite-preview/openai/v1", api_key="YOUR_FLYMYAI_KEY")
reply = client.chat.completions.create(
    model="flymyai/google-gemini-31-flash-lite-preview",
    messages=[{"role": "user", "content": "Explain in two sentences what an MCP server is."}],
