Capabilities

Claude Fable 5 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 Anthropic Messages API 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

    "max_tokens": 1024,
    "messages": [
      { "role": "user", "content": "Hello, who are you?" }
    ]
  }'

Pass anthropic/claude-fable-5 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 Anthropic SDK with its base URL pointed at https://089e99349ace.pikalabs.app/anthropic — no Pika-specific SDK is needed. Keep your Pika API key and existing Anthropic 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.
