## Examples

### CTA pointer

A wide green arrow aimed at an imagined "Start free trial" button on a promo banner.

API overrides that reproduce this example:

```json
{
  "star.path": "M 8 38 L 58 38 L 58 18 L 92 50 L 58 82 L 58 62 L 8 62 Z",
  "star.fillColor": "#10B981",
  "star.strokeColor": "transparent"
}
```

### Next-step arrow on dark

A crisp white arrow marking the flow between two imagined steps in a dark tutorial graphic.

API overrides that reproduce this example:

```json
{
  "star.path": "M 8 38 L 58 38 L 58 18 L 92 50 L 58 82 L 58 62 L 8 62 Z",
  "star.fillColor": "#F8FAFC",
  "star.strokeColor": "transparent"
}
```

## API overrides

Recolor per render with '<key>.fillColor' (or just '<key>'); strokeColor, strokeWidth and even the path are overridable.

Flat override payload (`key.property` addressing) with the sample design's current values — send only the keys you want to change:

```json
{
  "star.path": "M 50 5 L 61 38 L 95 38 L 68 59 L 79 92 L 50 70 L 21 92 L 32 59 L 5 38 L 39 38 Z",
  "star.viewBox": "0 0 100 100",
  "star.fillColor": "#F5A623",
  "star.strokeColor": "#D0021B",
  "star.strokeWidth": 0,
  "star.opacity": 1
}
```

```bash
curl --location 'https://render.imejis.io/v1/{{YOUR_DESIGN_ID}}' \
--header 'dma-api-key: {{YOUR_API_KEY}}' \
--header 'Content-Type: application/json' \
--data '{
    "star.path": "M 50 5 L 61 38 L 95 38 L 68 59 L 79 92 L 50 70 L 21 92 L 32 59 L 5 38 L 39 38 Z",
    "star.viewBox": "0 0 100 100",
    "star.fillColor": "#F5A623",
    "star.strokeColor": "#D0021B",
    "star.strokeWidth": 0,
    "star.opacity": 1
}'
```

`{{YOUR_DESIGN_ID}}` and `{{YOUR_API_KEY}}` are placeholders: first create
the design in your account (paste the sample design JSON above into the
editor at https://app.imejis.io, or create it programmatically via the
imejis MCP server's `create_design` + `update_design` tools), then render
it with the design's id and one of your API keys.

Agents: the MCP server at https://api.imejis.io/api/mcp exposes this same
catalog as structured data via the `list_component_types` tool (property
kinds, allowed values, bounds, ready-to-use sample designs).
