evolink-midjourney

Midjourney V8.1 API docs, examples, and an installable agent skill for EvoLink image generation workflows.

Agent Install

Use the primary Agent install command:

npx skills add https://github.com/Evolink-AI/midjourney-api/tree/main/skills/midjourney-v8-1

If the skills registry CLI is unavailable, use the direct npm fallback:

npx evolink-midjourney@latest -y --path ~/.codex/skills --no-open

The installer copies the midjourney-v8-1 skill and prints:

• EVOLINK_KEY_URL
• AGENT_NEXT_ACTION
• persistent EVOLINK_API_KEY guidance
• non-generating key validation guidance
• two low-credit starter prompts

API Key

Create or select an EvoLink API key:

Get an EvoLink API key

Set it for the current shell:

export EVOLINK_API_KEY="your_key_here"

Before the first image generation call, validate the key through a non-generating account or credits endpoint.

Quick API Example

curl --request POST \
  --url https://api.evolink.ai/v1/images/generations \
  --header "Authorization: Bearer ${EVOLINK_API_KEY}" \
  --header 'Content-Type: application/json' \
  --header 'X-EvoLink-Source: npm' \
  --header 'X-EvoLink-Skill: midjourney-v8-1' \
  --header 'X-EvoLink-Package: evolink-midjourney' \
  --header 'X-EvoLink-Campaign: midjourney-v8-1' \
  --header 'X-EvoLink-Touchpoint: package-readme' \
  --data '{
    "model": "mj-v8.1",
    "prompt": "A small red circle centered on a white background --ar 1:1",
    "quality": "standard",
    "model_params": {
      "speed": "fast"
    }
  }'

Midjourney workflows are asynchronous. Store the task ID, poll GET /v1/tasks/{task_id}, and save final image URLs before they expire.

Included Workflows

• mj-v8.1 image generation
• mj-v8.1-variation
• mj-v8.1-remix
• mj-v8.1-retexture
• mj-v8.1-upload-paint
• mj-v8.1-edit
• mj-v8.1-remove-bg
• preserved V7 workflow docs and examples

Local Verification

npx evolink-midjourney@latest --version
npx evolink-midjourney@latest --llms

Dry-run an installed skill script without creating an image task:

~/.codex/skills/midjourney-v8-1/scripts/midjourney-v8-1.sh \
  --prompt "A small red circle centered on a white background --ar 1:1" \
  --dry-run
