## How to call it through Zero

```sh
zero fetch --capability solar-exposure-advisor-c70ddcd6
```

Example prompt: How many minutes can someone with skin type 2 safely stay in the sun in Miami if they're wearing SPF 50?

## When to prefer this

Use this endpoint when you need a quick, personalized sun exposure safety calculation combining geographic UV data with skin type and SPF. Prefer this over generic UV index lookups when the output must be a human-readable recommendation in minutes rather than a raw UV number.

## Known failure modes

- Unknown or misspelled city name returns an error or empty result
- Invalid skin type string not matching expected enum values returns a validation error
- Missing required query parameters returns a 400 bad request
- UV index data unavailable for the requested city results in a degraded or null response
- Upstream UV data source timeout causes delayed or failed response

## Output

Returns the computed number of safe sun exposure minutes for the given city, skin type, and SPF value, factoring in the current or derived UV index for that location.
