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-agent-market-llm-chat-completion-llama-3-1-8b-15d489af
```

Example prompt: Ask the Llama 3.1 8B model: 'Explain the difference between supervised and unsupervised learning in plain English' — use a system message that says 'You are a concise AI tutor' and limit the response to 300 tokens.

## When to prefer this

Choose this endpoint when you need a fast, low-cost, keyless LLM completion using Llama 3.1 8B and are comfortable with pay-per-call x402 micropayments. Ideal for agents that need occasional LLM inference without managing API keys or subscriptions, or when integrating open-weight model inference into a pipeline at a flat $0.005 USDC per call. Prefer alternatives (e.g. OpenAI, Anthropic) when you need larger context windows, stronger reasoning, or specific model families.

## Known failure modes

- Missing required 'prompt' query parameter returns a 400 error
- Exceeding 2,000 max_tokens limit may truncate or error the response
- Payment not fulfilled (x402 protocol failure) results in a 402 Payment Required response
- Invalid temperature or max_tokens type causes a schema validation error
- Network timeout if the model takes too long to generate a lengthy response
