## 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-560e52d6 -d '<json body>'
```

Example prompt: Can you send the following conversation to the Orbonomy LLM chat endpoint and get a reply — messages: [{role: user, content: 'What is the capital of France?'}], with a max of 200 tokens?

## When to prefer this

Choose this endpoint when you need LLM chat completions on a pay-per-call basis without a subscription, especially when operating in an x402-enabled micropayment environment or when integrating AI chat into an agent that handles its own USDC payments.

## Known failure modes

- Missing required fields (messages or max_tokens) returns a validation error
- Payment failure via x402 protocol results in a 402 Payment Required response
- Exceeding model token limits may cause truncation or error
- Malformed messages array structure may result in a 400 Bad Request
- Service unavailability or upstream LLM provider outage returns a 5xx error
