Midjourney API Skill for RunAPI

Use Midjourney through the RunAPI CLI for one-off image generation, image editing, image-to-video, prompt analysis, and seed lookup. The canonical agent file is skills/midjourney/SKILL.md.

Variants

• V8.1 text to image: generate an image grid from a text prompt with runapi midjourney text-to-image.
• Image editing: transform a source image with a prompt using runapi midjourney edit-image.
• Image to video: animate a source image with runapi midjourney image-to-video.

Install

Install for Codex, Claude Code, Gemini CLI, Cursor, and other supported agents:

npx skills add runapi-ai/midjourney -g

Or paste this prompt to your AI agent:

Install the midjourney skill for me:

1. Clone https://github.com/runapi-ai/midjourney
2. Copy the skills/midjourney/ directory into your
   user-level skills directory.
3. Verify that SKILL.md is present.
4. Confirm the install path when done.

Claude Code can also install the repository skill directory into its user skills directory. Codex and Gemini CLI should use their user-level skills directories and keep SKILL.md at skills/midjourney/SKILL.md.

Commands

runapi midjourney text-to-image --input-file text-to-image.json
runapi midjourney edit-image --input-file edit-image.json
runapi midjourney image-to-video --input-file image-to-video.json
runapi midjourney image-to-prompt --input-file image-to-prompt.json
runapi midjourney get-seed --input-file get-seed.json

The first three commands create asynchronous tasks. image-to-prompt and get-seed return synchronously.
