FAQ
Frequently asked questions.
What is the Crizon AI API?
The Crizon AI API is CrizonShop's AI gateway: one API key (czn_…) calls many models through the same endpoint https://ai.crizonshop.com/v1, compatible with OpenAI Chat Completions, OpenAI Responses and Anthropic Messages.
Can I keep using the OpenAI SDK?
Yes. Keep your code and set base_url to https://ai.crizonshop.com/v1 and api_key to your czn_ key. The Anthropic SDK works with the same key too.
How do I use it with Claude Code?
Set ANTHROPIC_BASE_URL=https://ai.crizonshop.com (without /v1), ANTHROPIC_AUTH_TOKEN to your czn_ key and ANTHROPIC_MODEL to the model you want, then run claude. Or run crizon-ai setup claude and let the CLI configure it.
What are weighted tokens?
Models have different list prices, so every call is converted into one common unit: 1 million weighted tokens = 2 USD at list price. Each model has its own ratio for input, output and cache tokens, taken from the maker's official price.
How do I pay?
From your CrizonShop wallet: buy a plan with a weighted-token quota, or pay as you go when that option is on. Top up the wallet by bank transfer on CrizonShop.
Which models are available?
The "Models & pricing" table on this page comes straight from the system: open models and upcoming ones. Call GET /v1/models with your key to see exactly which models that key can use.
