What is the Midjourney API?

The Midjourney API gives applications programmatic access to Midjourney's V7, V8, and Niji image models without a Discord bot or manual prompting. Every request generates four image variations and can use a reference image to guide composition, style, or character appearance.

Muapi exposes all three variants through one REST API with pay-as-you-go pricing at $0.10 per run. Compare Midjourney with other text-to-image models before choosing a production endpoint.

Key Capabilities

Four Images Per Run

Each Midjourney request returns four image variations in one call, giving your application a ready-made set to review or rank.

V8 Coherence and Detail

Midjourney V8 improves scene coherence and fine detail over V7 for demanding photorealistic prompts.

Niji Anime and Illustration

Niji is tuned for anime, manga, character art, and stylized illustration rather than photorealistic output.

Reference Image Guidance

Pass source_image_url to influence composition, style, or character appearance across V7, V8, and Niji.

Use stylize, chaos, weird, negative_prompt, seed, and aspect_ratio to tune the request. Check the live Playground schema for the current field limits.

How to Call the Midjourney API

Send a prompt and optional reference image to the selected variant, save the returned request ID, and poll the shared result endpoint for four generated image URLs.

1. Generate four images

curl -X POST https://api.muapi.ai/api/v1/midjourney-v8 \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt":"A cinematic portrait in a rain-soaked neon city","aspect_ratio":"16:9","stylize":250}'

# Response: {"request_id":"REQUEST_ID"}

Call midjourney-v8, midjourney-v7, or midjourney-niji with prompt, aspect_ratio, and optional style controls or image_url.

2. Poll the result

curl https://api.muapi.ai/api/v1/predictions/REQUEST_ID/result \
  -H "x-api-key: YOUR_API_KEY"

# The completed response contains four generated image URLs.

Poll until the task is completed, then read the four generated image URLs from the response.
