Capabilities

GLM-5.2 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 OpenAI-compatible chat-completions 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.

X-API-Key: YOUR_API_KEY

Request

curl -X POST https://089e99349ace.pikalabs.app/v1/chat/completions \
  -H "X-API-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "z-ai/glm-5.2",
    "messages": [
      { "role": "user", "content": "Hello, who are you?" }
    ]
  }'

Pass z-ai/glm-5.2 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 OpenAI SDK with its base URL pointed at https://089e99349ace.pikalabs.app/v1 — no Pika-specific SDK is needed. Keep your Pika API key and existing OpenAI 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.
