## 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-agent-market-chat-completions-llama-3-1-8b-8afdb192
```

Example prompt: Ask the Llama 3.1 8B chat model 'What are three creative names for a coffee shop that focuses on sustainability?' using a system message that says 'You are a helpful branding expert', and cap the response at 300 tokens.

## When to prefer this

Choose this endpoint when you need a fast, OpenAI SDK-compatible chat completion without a monthly subscription, want per-request micropayment billing via x402 USDC, or are working with Meta Llama 3.1 8B specifically. Prefer it for lightweight, cost-controlled agentic workflows where paying per call is better than a flat-rate plan.

## Known failure modes

- Missing or empty prompt parameter returns a validation error
- Exceeding 2048 output tokens silently truncates or returns an error
- Payment failure via x402 results in a 402 Payment Required response
- Invalid model name passed to the model field returns a 404 or error response
- Malformed query parameters on GET requests cause a 400 Bad Request
