## 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 x402-nvidia-glm-4-chat-completions-via-micropayment-5cc3ce43 -d '<json body>'
```

Example prompt: Using the NVIDIA NIM GLM-4 model, answer this question for me: 'What are the main differences between transformer and diffusion architectures in deep learning?' — pay the per-call fee automatically.

## When to prefer this

Choose this endpoint when you need GLM-4/GLM-5 family model inference specifically hosted on NVIDIA NIM infrastructure and want pay-per-call billing via x402 USDC micropayments rather than a subscription. Ideal for agents that need occasional inference without committing to a monthly plan, or when ZhipuAI's GLM model specifically is required.

## Known failure modes

- Payment failure: x402 micropayment rejected or insufficient USDC balance
- Model unavailable: NVIDIA NIM endpoint for z-ai-glm5 is down or rate-limited
- Invalid input: malformed message array or missing required fields returns 400
- Timeout: model inference takes too long and request times out
- Authorization error: x402 payment header missing or invalid

## How this service works

Access 48+ NVIDIA NIM AI models via x402 micropayments. Chat completions, vision, safety, translation, and more.

## Output

Returns a choices array containing one or more assistant message objects, each with a role of 'assistant' and a content string containing the model's generated reply to the input prompt.
