gptzzz.ai
One account and balance for Claude, GPT, Grok and more
About gptzzz.ai
gptzzz.ai is an AI API relay for developers who want one account to reach models from several vendors, including Claude, GPT, Grok, DeepSeek and GLM. Usage is billed by volume from a single prepaid balance, and API keys are created per group, with each key tied to one group of models.
The service says it works with OpenAI-compatible clients by changing the base URL to gptzzz.ai/v1, while Claude groups use the Claude Messages endpoint. Group rate multipliers are published in a model plaza, with prices listed there. Recharges start at 10 yuan, and unused balance can be refunded on request.
It is run by an independent operator and is not an official service of any model vendor. Developers building backend services, coding assistants or tool-calling apps are the likely audience, and the site recommends keeping keys on the server side.
