Claude API:
cheap pay-as-you-go Opus, Sonnet and Haiku

Q: Which Claude models are supported?

Every Claude model in the price comparison on this page can be called (Opus, Sonnet, Haiku and more). New models are added to the Model Square when they go live.

Q: What is the difference between groups?

Channels and prices differ by group: group price = list price × group ratio. See "Claude groups" on this page; you can choose a group when creating a token.

Q: Are there rate limits?

The default is 60 RPM; higher limits are available on request.

Q: Can I call Claude with the OpenAI SDK?

Yes. Set base_url to https://api.88api.ai/v1 and use a Claude model name. Use /v1/messages when you need the native Anthropic request format.

One 88API token works with both Anthropic Messages and OpenAI Chat Completions to call Claude models. Pay as you go, with several price groups to choose from.
