How do I use the Z.AI API?

Create a Token Harbor key and call the OpenAI-compatible endpoint https://tokenharbor.ai/v1 (or the Anthropic endpoint https://tokenharbor.ai). One key gives you every Z.AI model plus hundreds of others — no separate Z.AI account required.

How much does the Z.AI API cost?

Z.AI models on Token Harbor start at $0.39 per 1M input tokens, pay-as-you-go with no subscription.
