## 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 longevitypulse-protocol-builder-048486b2
```

Example prompt: Build me a full personalized longevity protocol — I'm a 42-year-old woman, focused on healthspan and cognitive longevity, moderate budget, eat mostly Mediterranean food, and I want recommendations across Zone 2 cardio, strength training, VO2 max, nutrition, sleep, stress, and supplements.

## When to prefer this

Choose this endpoint when you need a holistic, multi-domain longevity protocol that integrates exercise, nutrition, sleep, stress, and supplements in a single personalized response — especially when the user's age, sex, budget, and cultural food preferences need to be factored in simultaneously. Prefer alternatives if the user only needs guidance on one isolated domain (e.g. supplement-only or diet-only analysis, which have dedicated sibling endpoints).

## Known failure modes

- Missing required parameters such as age or sex returns an error
- Unsupported or unrecognized food culture values may produce generic nutrition guidance
- Extremely low budget constraints may limit supplement and protocol recommendations
- Service unavailability returns a 5xx error from the Vercel deployment

## How this service works

Longevity / healthspan protocol builder (personalized anti-aging plan) for longevity and biohacker agents. Combines exercise (Zone 2, strength, VO2 max), nutrition, sleep, stress, and supplements, adapting to age, sex, goals, budget, and food culture worldwide. Health intelligence, not medical advice.

## Output

A comprehensive, personalized longevity protocol covering exercise zones (Zone 2, strength, VO2 max), nutrition guidelines, sleep optimization, stress management strategies, and a supplement stack — all adapted to the user's age, sex, goals, budget, and food culture.
