## 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 zeroreader-llama-3-2-1b-chat-completion-d59fbf92 -d '<json body>'
```

Example prompt: Can you use the ZeroReader Llama 1B model to quickly answer this question for me: 'What are three common uses of the Python requests library?' — keep it under 200 tokens and use temperature 0.5 for a focused response.

## When to prefer this

Choose this endpoint when you need the absolute fastest and cheapest LLM inference and your task is simple enough for a 1B parameter model — e.g. short Q&A, classification, simple summarization, or high-volume lightweight tasks where cost per call matters. Prefer larger sibling models (3B, 7B, 17B) when quality or reasoning depth is critical.

## Known failure modes

- Temperature out of range (0-2) returns validation error
- max_tokens exceeding 4096 is rejected
- Malformed messages array missing required role or content fields causes error
- Payment of 0.001 USDC not provided triggers 402 Payment Required
- Empty messages array may return an error or empty completion

## How this service works

Llama 3.2 1B — Smallest Llama. Fastest, cheapest.

## Output

Returns an OpenAI-compatible chat completion object containing the assistant's generated reply, a finish reason (e.g. 'stop'), a completion ID, and the full message object with role and content fields.
