## 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 emoji-tools-emoji-unicode-version-lookup-3f1a4c83
```

Example prompt: Which Emoji version first introduced the 🫶 heart hands emoji, and when was that version released?

## When to prefer this

Use this endpoint when you need authoritative version provenance for an emoji — specifically which Emoji standard version and Unicode version introduced it, and the exact release date. Prefer this over general emoji fact endpoints when the primary question is about versioning history or version-to-emoji mappings rather than visual appearance, vendor support, or keyword search.

## Known failure modes

- Unrecognized emoji or name returns null or empty results
- Invalid or future version numbers return no matching entries
- Ambiguous emoji names may return unexpected matches
- Service degraded flag may be set if data source is partially unavailable
- Network timeout or payment failure results in no response

## How this service works

Which Emoji and Unicode version introduced an emoji (with release date), or what an Emoji version added. No vendor claims.

## Output

Returns a structured object including the emoji character, its CLDR name, the Emoji version that introduced it (e.g. '13.0'), the corresponding Unicode version, the release date of that emoji version, codepoints, group/subgroup classification, a human-readable summary, and optional status/verdict/disclaimer fields. When querying by version number, returns what was added in that version.
