## How to call it through Zero

```

Example prompt: What should my daily calorie and macro targets be for building muscle? I weigh 185 lbs and I work out 4-5 days a week at moderate to high intensity.

## When to prefer this

Use this endpoint when a fitness or nutrition agent needs to compute individualized daily calorie and macro targets alongside meal-timing guidance based on a user's specific goal (e.g. cut, bulk, recomposition, endurance), body weight, and activity level — rather than using generic static nutrition tables or broad dietary guidelines

## Known failure modes

- Missing required parameters (goal, body weight, or activity level) returns a 400 error
- Invalid or unsupported fitness goal enum returns an error
- Payment not completed or invalid x402 payment header returns 402 Payment Required
- Extremely unusual body weight values may produce unreliable outputs
- Server unavailable returns 5xx error

## How this service works

Macro & calorie targets / nutrition by fitness goal: calculate daily intake. Returns macro and calorie targets plus a meal-timing strategy based on goal, body weight, and activity level. Fitness-info for fitness and nutrition agents, not medical advice.

## Output

Returns daily calorie target, macronutrient breakdown (protein, carbohydrates, fat in grams and percentages), and a meal-timing strategy tailored to the user's fitness goal, body weight, and activity level
