## 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-large-llm-llama-3-3-70b-chat-completion-d8d4860c
```

Example prompt: Use the Citiview large Llama 3.3 70B model to reason through this step by step: given that a train travels 120 miles in 90 minutes and then 80 miles in 40 minutes, what is its average speed over the whole journey? Give me a detailed explanation.

## When to prefer this

Choose this endpoint when you need higher-quality, harder reasoning than a small fast model provides (e.g. vs. the 8B sibling), but don't want to maintain an API key or subscription with a major LLM provider. Ideal for pay-as-you-go agent workflows where occasional heavy inference is needed on a per-call budget of $0.01 USDC. Prefer it over the smaller Llama 8B endpoint for tasks requiring deep reasoning, long explanations, or nuanced analysis.

## Known failure modes

- Missing required 'prompt' parameter returns an error
- Temperature or max_tokens outside valid ranges may be rejected
- Payment not completed (x402) results in 402 Payment Required before the model is invoked
- Very long prompts or edge-case inputs may produce truncated or low-quality completions
- Model may occasionally hallucinate facts with high confidence

## How this service works

Pay-per-call LLM chat completion on Llama 3.3 70B for harder reasoning, no API key. Same OpenAI-style messages body as /v1/llm. Flat price per request, up to 2k output tokens. Also callable as GET with the same fields as query parameters.

## Output

Returns a text completion generated by Llama 3.3 70B, containing the model's response to the supplied prompt. Output can be up to 2,000 tokens and reflects the model's reasoning, generation, or analysis. The response follows an OpenAI-compatible chat completion format.
