## 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 orbonomy-llm-chat-38e38cc4 -d '<json body>'
```

Example prompt: Ask the Orbonomy LLM chat endpoint: send these two messages — system: 'You are a helpful assistant', user: 'What are three tips for better sleep?' — with a max of 300 tokens and give me the response.

## When to prefer this

Choose this endpoint when you need a pay-per-call LLM chat completion without a subscription, especially in autonomous agent workflows where you want to pay per inference in USDC via the x402 protocol rather than managing API keys or monthly quotas.

## Known failure modes

- Payment not included or insufficient — 402 Payment Required response
- Missing required fields (messages or max_tokens) — 400 Bad Request
- max_tokens value too large or invalid — 422 Unprocessable Entity
- LLM provider unavailable — 503 or 500 error
- Empty messages array — validation error or unexpected model behavior
