Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 citiview-nemotron-120b-chat-completions-7da57cff
```

Example prompt: Ask the Nemotron 120B model: 'What are the pros and cons of microservices architecture?' — use a temperature of 0.7 and up to 512 tokens in the response.

## When to prefer this

Choose this endpoint when you need a very large (120B parameter) model with strong agentic reasoning and tool-calling capabilities, want OpenAI SDK compatibility without a subscription, prefer pay-per-call micropayment pricing via x402, or need to integrate a powerful LLM into an autonomous agent pipeline. Prefer over smaller models (e.g. Llama 3.1 8B on the same platform) when task complexity demands deeper reasoning or more nuanced outputs.

## Known failure modes

- Missing required prompt parameter returns 400 error
- x402 payment failure or insufficient USDC balance blocks the request
- Exceeding 4096 output token limit truncates response
- Invalid temperature or max_tokens values may cause 422 validation errors
- Network timeout on long reasoning chains with many tokens
- Tool calling schema errors if tool definitions are malformed
