## 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 foreverbetter-health-data-query-557dcc9f -d '<json body>'
```

Example prompt: Ask my ForeverBetter health workspace: based on my latest biomarker and genetics analyses, what are the most significant factors affecting my metabolic health?

## When to prefer this

Use this endpoint when you need to ask an open-ended natural-language question against a user's private, wallet-scoped health data — especially when the answer should be grounded in their actual biomarker results, genetics analyses, or wearable data rather than generic health information. Prefer this over the analysis-specific endpoints (recommendations, action plan, dashboard) when the question spans multiple analyses or data types, or when the user's intent is exploratory rather than requesting a specific structured output.

## Known failure modes

- No health data or analyses found for the wallet — returns empty or error response
- Ambiguous query that cannot be resolved against available data
- Invalid or inaccessible analysis_ids provided
- Payment not attached or insufficient USDC — request rejected
- Query outside the scope of stored health context — no grounded answer available

## How this service works

Ask a grounded question across health data and analyses owned by the paying wallet.

## Output

A grounded, data-backed answer derived from the wallet-owner's personal health data and analyses, potentially referencing specific biomarker values, genetic variants, wearable readings, or prior analysis outputs.
