Questions people actually ask.
What is the NinjaChat API?
NinjaChat is an all-in-one AI API: OpenAI, Anthropic, Google Gemini, Fal, and other labs — chat, image, and video generation — behind one OpenAI-compatible endpoint, one prepaid key (nj_sk_), and automatic provider failover. No lock-in to a single lab.
Is the NinjaChat API compatible with the OpenAI SDK?
Yes. Point base_url at https://www.ninjachat.ai/api/v1 and use an nj_sk_ key. Streaming, tool calls, JSON modes, and models.list work. Always use the www host — the apex domain redirects and most HTTP clients strip Authorization on that redirect.
Does NinjaChat include image and video generation?
Yes. The same key calls POST /v1/chat/completions, POST /v1/images/generations (synchronous), and POST /v1/videos (submit, then poll GET /v1/videos/{id} or register a webhook). Register webhooks at https://www.ninjachat.ai/developers/keys#webhooks. Image models include FLUX, Imagen 4, Recraft, and gpt-image-2. Video models include Veo, Kling, and Seedance.
How do I switch to NinjaChat from another AI provider?
For OpenAI-compatible clients, change the base URL and API key. Step-by-step guides for OpenAI, Anthropic, OpenRouter, Replicate, fal.ai, Together AI, Fireworks AI live at https://www.ninjachat.ai/migrate. Frameworks (Vercel AI SDK, LangChain, LlamaIndex, LiteLLM) keep working.
How is the NinjaChat API priced?
Pay as you go from one prepaid balance. Chat bills metered per-token rates. Images and video bill per generation. Prices live on GET /api/v1/models — no auth required. No credit card to start; $0.50 starter credit.
Where is the OpenAPI spec and the live model catalog?
OpenAPI 3.1 at https://www.ninjachat.ai/openapi.json (also GET /api/v1/openapi). Live catalog at GET /api/v1/models (no auth). Docs at https://docs.ninjachat.ai. Status at https://www.ninjachat.ai/status. Benchmarks at https://www.ninjachat.ai/benchmarks.
