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-llama-4-scout-chat-completions-5da074de
```

Example prompt: Ask Llama 4 Scout: 'What objects are visible in this image?' — send the image URL along with my question, keep it under 512 output tokens.

## When to prefer this

Choose this endpoint when you need a pay-per-request multimodal LLM with tool calling support and no monthly subscription, especially if you are already using the OpenAI SDK and want to swap in Llama 4 Scout by changing only the base URL. Ideal for agentic pipelines that process images alongside text, or for low-volume use cases where per-request x402 micropayments are more economical than a subscription tier.

## Known failure modes

- Payment not included or insufficient USDC via x402 — returns 402 Payment Required
- Prompt exceeds model context window — returns error or truncated response
- Invalid image URL provided for multimodal input — model may ignore image or return error
- max_tokens set above 2048 — may be capped or rejected
- Malformed tool definition schema — tool calling may fail or return unexpected format
- Model overloaded or unavailable — returns 503 or timeout
