# Yollomi AI API Skill

Generates images and videos via the Yollomi API. All models use a **single unified endpoint** with different `modelId` parameters.

## Setup

1. **API Key**: User must provide `YOLLOMI_API_KEY` (env var, .env file, or Cursor rule).
2. **Base URL** (optional): `YOLLOMI_BASE_URL` defaults to `https://yollomi.com`.

## Unified Endpoint

```
POST /api/v1/generate
```

**Headers**: `Authorization: Bearer ${YOLLOMI_API_KEY}` or `X-API-Key: ${YOLLOMI_API_KEY}`  
**Content-Type**: `application/json`

**Body**:
- `type` (required): `"image"` or `"video"`
- `modelId` (required): Model identifier
- Additional params depend on model (prompt, imageUrl, etc.)

**Response (image)**: `{ images: string[], remainingCredits: number }`  
**Response (video)**: `{ video: string, remainingCredits: number }`

## List Models

```
GET /api/v1/models
```

Returns all available image and video modelIds.

## Common Examples

**Generate image (Flux)**:
```bash
curl -X POST "${YOLLOMI_BASE_URL:-https://yollomi.com}/api/v1/generate" \
  -H "Authorization: Bearer $YOLLOMI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"type":"image","modelId":"flux","prompt":"A cat in a hat","aspectRatio":"1:1"}'
```

**Remove background**:
```bash
curl -X POST "${YOLLOMI_BASE_URL:-https://yollomi.com}/api/v1/generate" \
  -H "Authorization: Bearer $YOLLOMI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"type":"image","modelId":"remove-bg","imageUrl":"https://example.com/photo.jpg"}'
```

**Generate video**:
```bash
curl -X POST "${YOLLOMI_BASE_URL:-https://yollomi.com}/api/v1/generate" \
  -H "Authorization: Bearer $YOLLOMI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"type":"video","modelId":"kling-2-1","prompt":"A cat walking in the rain"}'
```

## Aspect Ratio (aspectRatio)

|------|------|
| 1:1 | 正方形（默认） |
| 16:9 | 横屏 |
| 9:16 | 竖屏 |

## Workflow

1. **Generate image** → POST /api/v1/generate with `type: "image"`, `modelId`, and model params
2. **Generate video** → POST /api/v1/generate with `type: "video"`, `modelId`, `prompt`, optional `inputs`
3. **List models** → GET /api/v1/models
4. **401/402** → Check API key and credits
