## Definitions

### `me.byjp.emojify.suggestEmoji`

**Type**: `query`

Suggest emoji whose meaning best matches a short passage of text.

#### Parameters

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `text` | `string` | Yes | The passage of text to match, up to 600 units. Despite the maxGraphemes field name, the limit is actually enforced in Unicode code points (runes), not user-perceived graphemes — a single multi-rune grapheme cluster (e.g. a ZWJ family emoji) counts as multiple units toward it. maxLength is in UTF-8 bytes, not runes — emoji-laden input can run up to 4 bytes per rune. Note that the underlying model reads at most 256 tokens (~1300 runes of ordinary English, far fewer for punctuation-dense text); anything beyond that is ignored rather than rejected, and a long passage whose subject is a small fraction of the text tends to yield a generic suggestion. |
| `limit` | `integer` | No | Maximum number of suggestions to return. |

#### Output

**Encoding**: `application/json`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `suggestions` | `array` | Yes |  |

#### Errors

- **TextTooLong**: text exceeds the 600-unit limit (counted in Unicode code points/runes, not graphemes).
- **NoMatch**: no suggestion cleared the minimum score.
- **RateLimitExceeded**: too many requests from this client; slow down and retry.
- **Overloaded**: the server is at capacity and shed this request; retry after a short delay.

### `me.byjp.emojify.suggestEmoji#suggestion`

**Type**: `object`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `name` | `string` | Yes | The emoji's CLDR label. |
| `emoji` | `string` | Yes | The suggested emoji. |
| `score` | `integer` | Yes | A similarity score — cosine similarity between the query and this emoji's meaning, adjusted by a per-emoji penalty that suppresses generically-matching emoji — expressed in per-mille (parts per thousand, 0-1000). This is not basis points (which would be parts per ten-thousand). Divide by 1000 for the 0..1 float value used internally — this is an integer because the lexicon primitive set has no float type. |
