Media Gen 🎬

Generate images and videos with AIsa using one API key.

This skill covers the current image and video model families exposed by AIsa across three different API shapes. The bundled client handles the endpoint differences for you, so you can choose a model and keep the same local workflow.

Use when: you want one neutral media-generation skill for AIsa image and video tasks, including cases where different models use different request schemas or response formats.

Compatibility

Works with any agentskills.io-compatible harness, including:

• Claude Code and Claude
• OpenAI Codex
• Cursor
• Gemini CLI
• OpenCode, Goose, OpenClaw, Hermes
• any other harness that implements the Agent Skills specification

Requires Python 3, a POSIX shell, and AISA_API_KEY (available from aisa.one).

What this skill covers

Image generation

• Google Gemini image generation via generateContent
• Alibaba Wan 2.7 image generation via chat-completions-style requests
• ByteDance Seedream image generation via the OpenAI-compatible images endpoint

Video generation

• Wan text-to-video
• Wan image-to-video
• async task creation, polling, waiting, and optional download through the bundled client

Example requests

Image — Gemini

"Generate a cyberpunk-style city nightscape, neon lights, rainy night, cinematic feel"

Image — Wan 2.7

"Generate an ultra-detailed product shot of a red panda, studio lighting, sharp focus"

Image — Seedream

"Generate a 2048×2048 magazine cover: neo-noir detective portrait, film grain"

Video — text-to-video

"Sweeping establishing shot of a neon cyberpunk skyline at dusk, 5 seconds"

Video — image-to-video

"Starting from this reference image, gentle camera push-in with parallax"

Supported models

Image generation — 4 models, 3 endpoints

Video generation — 4 Wan variants, 1 endpoint

Important schema difference for wan2.7-i2v: this model expects the reference image in input.media as an array of URLs, not input.img_url like wan2.6-i2v. If media is missing, the API can return HTTP 200 with a task_id and then fail downstream with InvalidParameter: Field required: input.media. The bundled client handles this automatically when you pass --img-url.

Quick start

export AISA_API_KEY="your-key"

# Any image model — the client routes to the correct endpoint
python3 scripts/media_gen_client.py image \
  --model gemini-3-pro-image-preview \
  --prompt "A cute red panda, cinematic lighting" \
  --out out.png

python3 scripts/media_gen_client.py image \
  --model wan2.7-image-pro \
  --prompt "Ultra-detailed product shot of a red panda" \
  --out out.png

python3 scripts/media_gen_client.py image \
  --model seedream-4-5-251128 \
  --prompt "Neo-noir detective portrait, film grain" \
  --size 2048x2048 \
  --out out.png

# Video — text-to-video
python3 scripts/media_gen_client.py video-create \
  --model wan2.7-t2v \
  --prompt "Sweeping shot of a neon cyberpunk skyline"

# Video — image-to-video on wan2.7-i2v
python3 scripts/media_gen_client.py video-create \
  --model wan2.7-i2v \
  --prompt "gentle zoom with parallax" \
  --img-url "https://example.com/reference.jpg" \
  --duration 5

# Wait and download
python3 scripts/media_gen_client.py video-wait \
  --task-id <task_id> --download --out out.mp4

Image generation endpoint reference

Gemini family → POST /v1/models/{model}:generateContent

Documentation: Google Gemini Chat.

curl -X POST "https://api.aisa.one/v1/models/gemini-3-pro-image-preview:generateContent" \
  -H "Authorization: Bearer $AISA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "contents":[
      {"role":"user","parts":[{"text":"A cute red panda, cinematic lighting"}]}
    ]
  }'

Response contains candidates[].parts[].inline_data with {mime_type, data}, where data is base64 image content.

Wan 2.7 family → POST /v1/chat/completions

Documentation: Image Generation via Chat.

Critical rule: messages[].content must be an array of typed parts. A plain string returns HTTP 400 invalid_parameter_error.

curl -X POST "https://api.aisa.one/v1/chat/completions" \
  -H "Authorization: Bearer $AISA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "wan2.7-image",
    "messages": [
      {"role":"user","content":[
        {"type":"text","text":"A cute red panda, ultra-detailed, cinematic lighting"}
      ]}
    ],
    "n": 1
  }'

Images return as {type: "image", image: "<url>"} parts inside choices[].message.content[].

Seedream → POST /v1/images/generations

Documentation: OpenAI-Compatible Image Generations.

curl -X POST "https://api.aisa.one/v1/images/generations" \
  -H "Authorization: Bearer $AISA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "seedream-4-5-251128",
    "prompt": "A cute red panda, ultra-detailed, cinematic lighting",
    "n": 1,
    "size": "2048x2048"
  }'

Response: data[].url or data[].b64_json.

Important: upstream enforces a minimum of 3,686,400 pixels. 1024x1024 and 1536x1536 are rejected. Any aspect ratio works as long as width × height ≥ 3,686,400.

Video generation endpoint reference

Create task → POST /apis/v1/services/aigc/video-generation/video-synthesis

Documentation: Create video generation task. Header X-DashScope-Async: enable is required.

# wan2.6-t2v — text-to-video
curl -X POST "https://api.aisa.one/apis/v1/services/aigc/video-generation/video-synthesis" \
  -H "Authorization: Bearer $AISA_API_KEY" \
  -H "Content-Type: application/json" \
  -H "X-DashScope-Async: enable" \
  -d '{
    "model":"wan2.6-t2v",
    "input":{"prompt":"cinematic close-up, slow push-in"},
    "parameters":{"resolution":"720P","duration":5}
  }'

# wan2.7-i2v — image-to-video (uses input.media, not input.img_url)
curl -X POST "https://api.aisa.one/apis/v1/services/aigc/video-generation/video-synthesis" \
  -H "Authorization: Bearer $AISA_API_KEY" \
  -H "Content-Type: application/json" \
  -H "X-DashScope-Async: enable" \
  -d '{
    "model":"wan2.7-i2v",
    "input":{
      "prompt":"gentle zoom with parallax",
      "media":["https://example.com/reference.jpg"]
    },
    "parameters":{"resolution":"720P","duration":5}
  }'

Poll task → GET /apis/v1/services/aigc/tasks/{task_id}

Documentation: Get video generation task result.

task_id is a path parameter. The query-string form ?task_id=... returns HTTP 500 unsupported uri.

curl "https://api.aisa.one/apis/v1/services/aigc/tasks/YOUR_TASK_ID" \
  -H "Authorization: Bearer $AISA_API_KEY"

Bundled Python client

The bundled client at scripts/media_gen_client.py auto-routes each image model to the correct endpoint and normalizes output to saved local files where applicable.

# Image — model selects the endpoint
python3 scripts/media_gen_client.py image \
  --model <gemini-3-pro-image-preview | wan2.7-image | wan2.7-image-pro | seedream-4-5-251128> \
  --prompt "..." \
  --out out.png

# Video — create task
python3 scripts/media_gen_client.py video-create \
  --model <wan2.6-t2v | wan2.6-i2v | wan2.7-t2v | wan2.7-i2v> \
  --prompt "..." \
  [--img-url https://... (required for -i2v models)] \
  [--duration 5|10] \
  [--resolution 720P|1080P]

# Video — poll / wait / download
python3 scripts/media_gen_client.py video-status --task-id <id>
python3 scripts/media_gen_client.py video-wait --task-id <id> --poll 10 --timeout 600
python3 scripts/media_gen_client.py video-wait --task-id <id> --download --out out.mp4
