OATDA Generate Image

Generate images from text descriptions using AI models through OATDA's unified API. Triggers when the user wants to generate, create, or produce AI images, artwork, illustrations, designs, mockups, or concept art using DALL-E 3, GPT-Image-1, Google Imagen, Bytedance Seedream, Alibaba Wan, MiniMax, xAI Grok image models, or other image generation models via OATDA.

OATDA Image Generation

Generate images from text descriptions using AI models through OATDA's unified API.

API Key Resolution

All commands need the OATDA API key. Resolve it inline for each exec call:

bash

export OATDA_API_KEY="${OATDA_API_KEY:-$(cat ~/.oatda/credentials.json 2>/dev/null | jq -r '.profiles[.defaultProfile].apiKey' 2>/dev/null)}"

If the key is empty or null, tell the user to get one at https://oatda.com and configure it.

Security: Never print the full API key. Only verify existence or show first 8 chars.

Model Mapping

User says	Provider	Model
dall-e, dall-e-3 (default)	openai	dall-e-3
gpt-image	openai	gpt-image-1
imagen	google	imagen-4.0-generate-001
seedream	bytedance	seedream-4-5-251128
wan	alibaba	wan2.6-t2i
minimax image	minimax	image-01
grok image	xai	grok-imagine-image

Default: openai / dall-e-3 if no model specified.

⚠️ Models update frequently. If a model ID fails, query oatda-list-models with ?type=image for the latest available models.

Discovering Model-Specific Parameters

Different models support different parameters (sizes, quality, styles, masks, watermarks, negative prompts, etc.). Query before generating:

bash

export OATDA_API_KEY="${OATDA_API_KEY:-$(cat ~/.oatda/credentials.json 2>/dev/null | jq -r '.profiles[.defaultProfile].apiKey' 2>/dev/null)}" && \
curl -s -X GET "https://oatda.com/api/v1/llm/models?type=image" \
  -H "Authorization: Bearer $OATDA_API_KEY" | jq '.image_models[] | {id, supported_params}'

This returns each model's supported_params with type, allowed values, defaults, and descriptions. File-type parameters (like mask) require public URLs.

API Call

CRITICAL: The endpoint is /api/v1/llm/generate-image (NOT /api/v1/llm/image — that's vision analysis).

bash

export OATDA_API_KEY="${OATDA_API_KEY:-$(cat ~/.oatda/credentials.json 2>/dev/null | jq -r '.profiles[.defaultProfile].apiKey' 2>/dev/null)}" && \
curl -s -X POST "https://oatda.com/api/v1/llm/generate-image" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $OATDA_API_KEY" \
  -d '{
    "provider": "<PROVIDER>",
    "model": "<MODEL>",
    "prompt": "<IMAGE_DESCRIPTION>",
    "size": "1024x1024",
    "quality": "standard",
    "n": 1,
    "numberOfImages": 1
  }'

Common Parameters

• prompt: Image description (1-4000 characters)
• size: "1024x1024", "1792x1024", "1024x1792", "2K", "4K" (model-dependent)
• quality: "standard", "hd", "auto", "low", "medium", "high"
• n and numberOfImages: Number of images (1-10) — set both to same value
• aspectRatio: "1:1", "16:9", "9:16", "3:2", "2:3", "4:3", "3:4"
• style: "vivid" (dramatic) or "natural" (realistic)
• background: "auto", "transparent", "opaque"
• outputFormat: "png", "jpeg", "webp"
• model_params: Model-specific key-value pairs (see discovery above)

model_params Examples

• DALL-E 3: {"style": "vivid", "quality": "hd"}
• GPT-Image-1: {"quality": "high", "background": "transparent", "outputFormat": "png"}
• Imagen 4: {"sampleImageSize": "2K", "personGeneration": "allow_adult"}
• Seedream: {"size": "4K", "watermark": false}
• Wan 2.6: {"seed": "42", "negative_prompt": "blurry", "prompt_extend": true}

Response Format

json

{
  "success": true,
  "url": "https://cdn.example.com/generated-image.png",

}

Show image URL(s) from all_images array (or url field if single). Mention revised_prompt if present.

Error Handling

HTTP Status	Meaning	Action
401	Invalid API key	Tell user to check their key
400	Bad request / prompt too long	Keep prompt under 4000 chars
429	Rate limited	Wait 5 seconds and retry once
400 + content_policy	Content policy violation	Ask user to adjust description

Notes

• Endpoint is /api/v1/llm/generate-image — NOT /api/v1/llm/image (vision analysis)
• Set both n and numberOfImages to the same value for compatibility
• Image URLs may be temporary — recommend downloading promptly
• Max prompt length: 4000 characters
• Use oatda-vision-analysis for analyzing images
• Use oatda-list-models for available image models
• In Telegram/chat: Extract only the image URL from the response (jq -r '.url'), do NOT dump raw JSON. Present as clickable link or describe the image.
