## How to call it through Zero

```sh
zero fetch --capability saylor-innovations-pet-age-converter-384e5abe
```

Example prompt: My golden retriever Max is 8 years old and he's a large breed — what's his human-equivalent age, what life stage is he in, and what care schedule should I be following?

## When to prefer this

Use this endpoint when you need to translate a pet's chronological age into a human-equivalent framework, understand what life stage they are in, or retrieve care schedule guidance tied to that stage. It is especially useful for dog owners who want size-adjusted results (toy through giant breeds age differently). Prefer this over generic pet info sources when you need a structured, parameterized computation rather than a free-text article.

## Known failure modes

- Missing required 'species' or 'age_years' parameter returns an error
- Invalid species value (not 'dog' or 'cat') may return an error or unexpected result
- Negative or implausible age values may produce errors
- Invalid size value for dogs may fall back to default 'medium' or return an error
- Network or upstream API downtime returns a non-200 response

## How this service works

Human-equivalent age, life stage, life expectancy and care schedule by stage

## Output

Returns the pet's human-equivalent age as a number, their current life stage (e.g. kitten, young adult, mature, senior), estimated life expectancy, and a care schedule or care recommendations appropriate to that life stage.
