--- name: yollomi-ai-api description: AI image generator skill (image, image generation). Multi-model image generator for Yollomi to generate AI images via one unified API endpoint. Requires YOLLOMI_API_KEY. metadata: {"openclaw":{"requires":{"env":["YOLLOMI_API_KEY"]}}} ---

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: Set YOLLOMI_API_KEY (environment variable).
2. Base URL (optional): Set YOLLOMI_BASE_URL to override API host (default: 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):

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:

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:

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)

Supported aspect ratios for text-to-image models:

| ratio | description | |------|-------------| | 1:1 | Square (default) | | 16:9 | Landscape | | 9:16 | Portrait |

OpenClaw Tools

| Tool | Description | |------|-------------| | yollomi.generate | Generate image or video. Params: type, modelId, prompt, imageUrl, aspectRatio, numOutputs, inputs (video) | | yollomi.listModels | List all available image and video models with credit costs. No auth required. |

Workflow

1. List models → yollomi.listModels() or GET /api/v1/models
2. Generate image → yollomi.generate({ type: "image", modelId, prompt, ... })
3. Generate video → yollomi.generate({ type: "video", modelId, prompt, inputs: { ... } })
4. 401/402 → Check API key and credits
