## 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-minimax-m2-chat-completions-308940f5 -d '<json body>'
```

Example prompt: Send my conversation to MiniMax M2 on NVIDIA NIM and get a reply: system says 'You are a helpful assistant,' and the user says 'Explain quantum entanglement in simple terms.'

## When to prefer this

Choose this endpoint when you specifically need MiniMax-M2 model inference via NVIDIA NIM and are already using or comfortable with x402 micropayment flows. Prefer it over generic OpenAI-compatible endpoints when MiniMax-M2's architecture or performance characteristics are desired, or when you want pay-per-call pricing without API key subscription management.

## Known failure modes

- Payment not provided or insufficient — x402 payment required before model responds
- Invalid or malformed message array — returns 4xx error
- Model unavailable or NVIDIA NIM service down — returns 5xx error
- Rate limit exceeded — too many calls in a short window
- Empty or missing choices in response if model produces no output

## How this service works

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

## Output

A chat completion response containing an array of choices, each with an assistant message object including role and content fields — the model's generated reply to the input conversation.
