## How to call it through Zero

```sh
zero fetch --capability emoji-tools-skin-tone-variants-ddbbcb55
```

Example prompt: What are all five skin-tone variants of the waving hand emoji 👋 — give me each variant's name, character, and codepoints, or tell me if it doesn't support tone modifiers.

## When to prefer this

Use this endpoint when you specifically need the full set of five Fitzpatrick skin-tone variants for a single emoji, including their individual codepoints and names, or when you need to determine programmatically whether a given emoji supports skin-tone modification and why. Prefer it over general emoji lookup endpoints (which return single-emoji facts) when your task involves rendering, accessibility review, or building an emoji picker that must enumerate tone variants.

## Known failure modes

- Emoji not recognized — returns null base or error if the input string is not a valid emoji or name
- No skin-tone variants — returns supportsToneModifiers: false with reasons array if the emoji inherently cannot be skin-toned
- Input is already a toned variant — endpoint resolves to the base and still returns all five variants
- Malformed query param — missing or empty 'emoji' param returns a validation error
- Degraded response — partial data returned with degraded: true flag if upstream Unicode data is incomplete

## How this service works

The five skin-tone variants (light to dark) of a base emoji with code points and names, or why it has none.

## Output

Returns an object containing the base emoji's metadata, a list of up to five skin-tone variants each with their emoji character, tone label, name, and codepoints, the Fitzpatrick modifier codepoints used, a boolean indicating whether tone modifiers are supported, and if not supported, an array of reasons explaining why.
