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 agentrxi-llama-3-2-1b-instruct-chat-completions-eab3b2ec
```

Example prompt: Ask Llama 3.2 1B: 'What are three practical tips for writing clear technical documentation?' — keep it under 200 tokens and use a temperature of 0.7.

## When to prefer this

Choose this endpoint when you need a very fast, low-cost LLM inference call with no API key or signup — ideal for simple classification, short translations, quick drafts, or agentic subtasks where a small 1B model suffices. Prefer this over larger models when latency and cost are top priorities and the task does not require deep reasoning or long context.

## Known failure modes

- Missing required 'prompt' query parameter returns a validation error
- Exceeding max_tokens budget may truncate output prematurely
- Model may produce low-quality output for complex reasoning tasks given its 1B parameter size
- USDC payment failure or insufficient balance blocks the call
- High temperature values may produce incoherent or repetitive output

## Output

Returns an OpenAI-compatible JSON object containing the assistant's generated message text, finish reason (e.g. 'stop'), token usage breakdown (prompt tokens, completion tokens, total tokens), model name ('llama-3.2-1b-instruct'), and a unique completion ID.
