Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```

Example prompt: Ask Sally: what are the main factors that affect metabolic rate, and how can I tell if my metabolism is slow?

Use this endpoint when a user wants to ask a conversational question about health, metabolic function, nutrition, or wellness and receive a natural language answer from an AI assistant named Sally. Best for open-ended health Q&A rather than structured data lookups.
