## 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-7fb59789 -d '<json body>'
```

Example prompt: Ask the Orbonomy LLM chat endpoint this: 'What are three creative names for a pet goldfish?' — send it as a user message and limit the response to 150 tokens.

## When to prefer this

Choose this endpoint when you need a pay-per-call LLM chat completion without a subscription, especially when operating in a crypto-native or x402-enabled payment environment and want to avoid committing to a recurring API key plan.
