## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability imgnai-katana-glm-52-text-completion-49568553 -d '<json body>'
```

Example prompt: Ask GLM-52 on the Katana gateway to answer the following using these messages: system says 'You are a helpful assistant' and user says 'Explain quantum entanglement in two sentences', with temperature 0.7 and a max of 300 tokens.
