Capabilities

Gemini 3.1 Pro is a language model served through the Pika developer API. Send it a list of chat messages and it streams back a text reply, using the GenAI generateContent shape.

Authentication

api key header

The Pika API uses API keys to authenticate requests. Send your key in the X-API-Keyheader. Your API key is a secret. Don't expose it in browsers or other client-side code. Instead, call the API from your server. The signed-in playground uses a portal session and never sends your API key.

header
X-API-Key: YOUR_API_KEY

Request

POST /genai/v1beta/models/gemini-3.1-pro:generateContent

Request

curl -X POST https://api.dev.pika.art/genai/v1beta/models/gemini-3.1-pro:generateContent \
  -H "X-API-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "contents": [
      { "role": "user", "parts": [{ "text": "Hello, who are you?" }] }
    ]
  }'

Pass google/gemini-3.1-pro as the model and a messages array of { role, content } turns. Set stream: true to receive tokens incrementally over server-sent events.

The Python and TypeScript examples use the official Google GenAI SDK with its base URL pointed at https://api.dev.pika.art/genai — no Pika-specific SDK is needed. Keep your Pika API key and existing Google GenAI code works without a rewrite.

Errors

shared across calls

Errors use conventional HTTP status codes with a JSON body of the shape {"message": "..."}. A missing or invalid key returns 401.
