AI API Credits Explained: Claude, Codex & DeepSeek
What a redeem code for Claude, Codex (GPT), Kimi, GLM or DeepSeek tokens gives you, how to set it up in your own tools, and how long the tokens last. API credits let you use AI models from your own apps, scripts and coding tools, paying for tokens instead of a monthly plan. Here is what you get, and what to check before you choose.
What you buy
Each option is a redeem code for a number of tokens: 10M, 50M, 100M or 500M (Kimi, GLM and DeepSeek start at 50M). You redeem it with an API service that serves the models, and use the tokens with an API key in the sk-... format. Claude API Credits: Claude models. Codex API Credits: OpenAI's Codex (GPT) models. Claude + GPT API Credits: Claude and GPT models with the same key, to switch between them. Kimi, GLM & DeepSeek API Credits: Moonshot's Kimi, Zhipu's GLM and DeepSeek models with the same key.
Whose API it is
The tokens are not from Anthropic, OpenAI or the models' other makers. They come from an API service that serves these models through its own base URL. That is why your tool needs two things: the API key and the service's base URL. Where to redeem the code, the base URL and a setup guide come with your order.
How to use the tokens
Pay for the option you chose. The redeem code is in your order, under My orders, usually right after the payment is confirmed. Redeem the code where your order says. It creates a new API key, or adds the tokens to a key you already have. In your app, script or coding tool, set the API key and the base URL from the setup guide. Use the models as usual. You can buy several codes and combine their tokens. The credits work in any tool that lets you set an API key and a base URL: check that yours does before you buy.
How long the tokens last
Each option says how many days you have to use its tokens, and bigger options give more days: 10M tokens: 1 day. 50M tokens: 2 days. 100M tokens: 3 days (4 days for Kimi, GLM & DeepSeek). 500M tokens: 6 days (7 days for Kimi, GLM & DeepSeek). Choose the size you will use in that time. Each option's warranty covers the same days, counted from delivery.
Which one to choose
For Claude in a coding tool or your own app: Claude API Credits. For OpenAI's Codex (GPT) models: Codex API Credits. To switch between Claude and GPT without changing keys: Claude + GPT API Credits. For Kimi, GLM or DeepSeek: Kimi, GLM & DeepSeek API Credits. Not sure how many tokens you need? Start small: you can redeem more codes on the same key later.
If something does not work
