# Skill: effect/sticker-slam — "מדבקת מילת מפתח" (Keyword sticker slam)

A white sticker with the key word in red slams in, tilted — the call-to-action label.

Price: **60 credits per finished minute**: the render itself — 1 credit per second of 1080p output. Combined with captions, a hook or other effects: still one render, nothing more for combining.

## 1. On its own — one call

```jsonc
POST /v1/effects/sticker-slam             // x-wait-ms: 110000
{
  "video_url": "https://media.gpt.org.il/samples/sample-he.mp4",
  "text": "תגיבו *נוסחה*",
  "params": {
    "y": 24
  },
  "start": 0.4,
  "duration": 3.4
}
```

A normal render: `status: processing` → poll `GET /v1/executions/{id}` until `completed`, then read `output.url`.
Leave out `video_url` and the effect is drawn on a plain black canvas (9:16 unless `output.aspect_ratio` says otherwise).

When it plays: a stretch: `start` + `duration` (seconds of the finished video), or `at` (a word id) + `duration`, or `during` { from, to } (word ids).

## 2. With captions, a hook and other effects — the same render

```jsonc
POST /v1/studio/edit               // x-wait-ms: 110000
{
  "video_url": "<the video>",
  "language_code": "he",
  "captions": {
    "style": "classic"
  },
  "effects": [
    {
      "id": "sticker-slam",
      "params": {
        "y": 24,
        "text": "תגיבו *נוסחה*"
      },
      "start": 0.4,
      "duration": 3.4
    }
  ],
  "audio": {
    "normalize": true
  },
  "output": {
    "aspect_ratio": "9:16",
    "resolution": "1080",
    "fit": "crop",
    "quality": "high"
  }
}
```

`effects` is a list: add more entries for more effects. The engine applies them by pipeline stage (cuts and time →
camera → grade and looks → overlays → text and captions → sound), never by their order in the list. An edit has one
`transition`, one `color` grade, one `music` bed, one `speed` and one caption style: two effects that set the same
one are refused with a message that names them.

## 3. Params

| param | default | range / options | what it does |
|---|---|---|---|
| `text` | **required** | string | The words (*word* = the accent colour · ~word~ = struck through · \n = a smaller second line) |
| `size` | `6` | 2–30 | Letter size, % of the frame height |
| `color` | `"#111111"` | string | Text colour |
| `accent_color` | `"#DE124B"` | string | Colour of the *marked* key word |
| `background` | `"#FFFFFF"` | value | A box behind the text (null = none) |
| `font` | `"Heebo"` | string | Font family — GET /v1/studio/fonts |
| `position` | `"top"` | `top` · `center` · `bottom` | Where the block sits |
| `y` | — | 0–100 | Exact height of the block's centre, % from the top (overrides position) |
| `exit` | `"fade"` | `none` · `fade` · `smear` · `blur` | How it leaves: none · fade · smear · blur |
| `rotate` | `-3` | -20–20 | Tilt, degrees |

GET `/v1/effects/sticker-slam` returns the same as JSON (with the full body schema). Every field has a default; numbers
outside their range are refused with the field's name.
