# Emoji Tools – Single Emoji Info

> Emoji Tools – Single Emoji Info is a paid API for AI agents from emoji-tools.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-11-02).

Returns detailed technical facts about one emoji: codepoints, CLDR name, Unicode group/subgroup, Emoji version, qualification status, ZWJ sequence breakdown, skin tone metadata, and UTF-8/UTF-16 encoding lengths.

## Facts

- Endpoint: GET https://emoji-tools.x402tookit.com/emoji-info?utm_source=zero.xyz
- Price: $0.02/call

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-single-emoji-info-305077b2
```

Example prompt: What are the Unicode codepoints, Emoji version, and UTF-8 byte length for 👍🏽 — the medium-skin-tone thumbs up?

## When to prefer this

Use this endpoint when you need precise, standards-based technical metadata for a single emoji — codepoints, encoding lengths, qualification status, ZWJ breakdown, or skin tone support. It is the right choice over generic Unicode libraries when you need CLDR-aligned names, Emoji version attribution, or skin-tone variant counts without running local code. Prefer this over the search or list endpoints when you already have the specific emoji character, its codepoints, or its CLDR name.

## Known failure modes

- Emoji not found in CLDR database returns null fields or an error status
- Ambiguous CLDR name (e.g. 'heart') may match multiple emoji — only one result returned
- Invalid codepoint format returns an error or empty result
- Very new emoji not yet in the dataset may return missing version data
- Truncated or malformed emoji input (incomplete ZWJ sequence) may yield partial results

## How this service works

Facts on one emoji: codepoints, CLDR name, group, Emoji version, qualification, ZWJ parts, skin tones, UTF-8/16 lengths.

## Output

A JSON object containing the emoji character, its CLDR name, Unicode group and subgroup, Emoji version of introduction, qualification status (fully-qualified, unqualified, etc.), ZWJ sequence flag and component parts, skin tone metadata (tone name, whether it is a tone variant, count of uniform and mixed variants, whether it supports modifiers), encoding details (UTF-8 byte count, UTF-16 code unit count, codepoint list, JavaScript string length, grapheme cluster count), keywords, shortcodes, and the field by which the query was matched.
