## 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 nexus-ai-deliver-49d23dfd -d '<json body>'
```

Example prompt: Use Nexus AI to handle this for me: 'Summarize the key risks in this project plan and suggest mitigation steps for each one.'

## When to prefer this

Choose this endpoint when you need to invoke Nexus AI's operational orchestration and execution capabilities via a chat-style message interface and are operating in an x402 micropayment-enabled environment. Prefer it when you want a single-turn AI response from an orchestration-focused system rather than a general-purpose LLM API.

- Missing or empty message field returns a 400 Bad Request
- Payment not included or insufficient USDC triggers a 402 Payment Required
- Nexus AI execution failure returns a 500 Internal Server Error
- Malformed JSON body results in a parse error response
