Capabilities
DeepSeek V4 Flash 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-Key header. 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.

Request
curl -X POST https://api.dev.pika.art/v1/chat/completions \-H "X-API-Key: YOUR_API_KEY" \-H "Content-Type: application/json" \-d '{"model": "deepseek/deepseek-v4-flash","messages": [{ "role": "user", "content": "Hello, who are you?" }]}'
Pass deepseek/deepseek-v4-flash 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://api.dev.pika.art/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.
