Midjourney V8.1 API

Use Midjourney V8.1 in production image workflows through EvoLink. Test prompts in the browser playground, send async generation requests with one EvoLink key, use image-to-image and Omni Reference workflows, then poll or receive callbacks for results. 10 free credits on signup.

Billing Rules

•Fast returns 4 images per request — some may be filtered by content review, so you get 1–4 back.
•Credits are charged per request, not per image.
•Draft and Fast are billed the same (1×).
•HD (2K) adds a further 1.5× multiplier, stacking with the speed tier (e.g. Fast + HD = 1.5× the base).
•Draft (sketch) returns 24 images at 0.5K instead, and cannot be combined with HD.

What Can You Build with Midjourney V8.1?

Product Photography and Commerce Visuals

Build commercial image pipelines with Midjourney V8.1. This is a strong fit for midjourney product photography use cases, including ecommerce packshots, product mockups, ad creatives, and branded concept images.

Midjourney Image to Image Workflows

Guide every generation with reference images. The Midjourney V8.1 API supports midjourney image to image through image prompts, Omni Reference (--oref), Style Reference (--sref), and image weight (--iw) for repeatable, style-consistent output.

Reference Image Workflows with Omni Reference

Use a Midjourney reference image to anchor the subject, object, or scene of every generation. The Midjourney V8.1 API supports Omni Reference (--oref) and Style Reference (--sref) so teams can build repeatable, brand-consistent image pipelines.

Why Choose Midjourney V8.1 API?

Access Midjourney V8.1 through evolink.ai with standard/HD quality options, transparent per-request pricing, async task handling, unified credits, and one EvoLink key for production image workflows.

Standard/HD Quality Options and Speed Tiers

The EvoLink V8.1 route exposes output quality through the top-level quality parameter — standard for 1080p, hd for 2K — plus Draft and Fast speed tiers for balancing cost, queue priority, and output quality. Use the pricing table on this page as the billing source of truth for each combination.

Native MJ Syntax

Use supported Midjourney-style parameters directly in your prompts, including --ar for aspect ratio, --s for stylize, --chaos for variation, --sref for Style Reference, --oref for Omni Reference, --iw for image weight, --seed, --raw, and related reference controls. Speed is passed via model_params and output quality via the top-level quality parameter (standard or hd), not in the prompt.

Enterprise-Ready Infrastructure

EvoLink wraps the V8.1 route in an async API workflow with task IDs, status polling, callback support, unified credits, and API-key authentication, so teams can integrate image generation without building separate routing and billing logic.

Construct Your Payload

Define your prompt with native MJ syntax, choose a speed tier (draft/fast), and optionally provide reference images. Our developer-friendly docs make configuration intuitive.

Retrieve and Display

Send the request and poll for results. Fast returns up to 4 high-quality images per request, while Draft returns 24 lightweight sketches for fast ideation. Our optimized delivery network ensures reliable performance.

Key Capabilities of Midjourney V8.1

Explore the technical strengths of MJ V8.1 accessible via our platform.

Quality

Standard/HD Quality Options

Choose standard (1080p) for everyday work or hd (2K) when you need a sharper final image. Output quality is controlled through the top-level quality parameter and billed according to the pricing table on this page.

Power

Native Prompt Syntax

Supports the V8.1 prompt controls exposed by this route: --ar (aspect ratio), --s (stylize), --chaos, --exp, --raw, --seed, --sref (Style Reference), --oref (Omni Reference), --iw (image weight), --sw (style weight), and --ow (Omni weight). The version is locked to V8.1, so --v is handled for you.

Flexibility

Two Speed Tiers

Draft (1x) and Fast (1x) modes let you balance cost vs. priority for every request. Use standard quality for default output, or hd quality for sharper final assets when needed.

Control

Omni and Style Reference

Use --oref (Omni Reference) to anchor subjects across generations and --sref (Style Reference) for style transfer, with adjustable --sw weight. These controls are especially useful for midjourney personalization, brand-consistent product photography, and reusable style systems.

Architecture

Async Processing

Asynchronous task handling with progress tracking. Poll for status or use a callback_url to receive completion, failure, or cancellation events.

Safety

Content Review

Built-in content safety filtering. Each image is individually reviewed — up to 4 for Fast, 24 lightweight sketches for Draft — and only approved images are returned in the results.

Midjourney V8.1 vs Other Image APIs

Model	Best fit	Where it wins	When to choose it
Midjourney V8.1	Production image generation, product photography, reference-image workflows	MJ-style prompt control, Omni Reference, Style Reference, Fast generations with up to 4 images, Draft sketch mode with up to 24 lightweight images, and standard/HD quality options on one EvoLink route	Choose it when visual direction, subject anchoring, and Midjourney-style creative control matter more than raw lowest cost.
Midjourney V7	Existing Midjourney V7 pipelines and stable legacy workflows	Same Midjourney family with familiar workflow patterns and existing EvoLink route support	Choose it when you already built around V7 behavior or need to keep an older production route unchanged.
Nano Banana Pro	Image editing, product mockups, text-heavy visuals, and Google Gemini image workflows	Strong instruction following, conversational image iteration, and high-fidelity visual editing through the Gemini image stack	Choose it when editable mockups, readable text, or Gemini-native workflows are more important than MJ prompt syntax.
GPT Image 2	OpenAI image workflows, world-knowledge-aware generation, and precise instruction following	Uses text and image understanding with strong contextual awareness through OpenAI's image generation API	Choose it when your app already uses OpenAI APIs or needs image generation tied closely to broader reasoning workflows.

Frequently Asked Questions

Everything you need to know about the product and billing.

Midjourney does not currently publish a public developer API in its public docs. EvoLink provides a managed Midjourney V8.1 API route: one API key, supported MJ-style prompt syntax, async task IDs, and per-request billing. Use this page when you need to call V8.1 from code through EvoLink.

Midjourney V8.1 API pricing on EvoLink is per request, not per image. Standard generation (text-to-image and image-to-image) starts at $0.075 per request at Fast + standard quality and goes up to $0.1125 at Fast + hd quality. Variant operations — variation, remix, canvas edit, advanced edit, and retexture — are a flat $0.1125 (Fast). Remove-background is a flat $0.075. Speed tiers are Draft (1x) and Fast (1x); quality options are standard (1x) and hd (1.5x). Draft and Fast cost the same — there is no half-price draft.

New EvoLink accounts receive 10 free credits on signup, which you can spend on the Midjourney V8.1 API directly from the playground on this page. It is the simplest way to test image-to-image, Omni Reference, and product photography workflows before any paid commitment.

Full Midjourney V8.1 API documentation — endpoint, parameters, async task lifecycle, callback URL, and error codes — lives in the EvoLink API manual. You can also try every parameter live in the playground above before integrating.

For midjourney image to image on the main generation route, place reference image URLs at the start of your prompt. The API supports one image URL plus text, two or more image URLs with or without text, and reference URLs combined with --iw (image weight) to tune influence. A single image URL with no text is rejected by Midjourney.

Yes. The Midjourney V8.1 route supports Omni Reference via --oref to anchor subjects, objects, or scenes across generations, and Style Reference via --sref with adjustable --sw style weight. These are the right controls for repeatable brand visuals, midjourney product photography, and consistent creative direction.

Inside the prompt, the V8.1 API accepts the supported route parameters shown in the API reference and Prompt Builder, including --ar, --s, --chaos, --exp, --raw, --seed, --iw, --sref, --sw, --oref, and --ow. Speed is passed via model_params and output quality via the top-level quality parameter (standard or hd), not in the prompt. The version is locked to V8.1, so --v is handled for you. Character Reference (--cref), --cw, --tile, --weird, --niji, --q, and --no are not exposed on this route; use --oref in place of --cref.

Yes. Midjourney V8.1 is a strong fit for midjourney product photography: hero shots, ecommerce packshots, launch visuals, mockups, and ad creatives. Pair a clean prompt with Omni Reference (--oref) for subject anchoring and Style Reference (--sref) for brand-consistent lighting and material direction.

A strong midjourney image prompt covers subject, composition, environment, lighting, camera or rendering cues, and style goal. Then add parameters: --ar for ratio, --s for stylize, --iw for reference weight, and --sref or --oref when you need repeatability. The Prompt Builder on this page assembles valid V8.1 prompts for you.

It depends on the speed tier. Fast returns up to 4 image variations per request, while Draft returns 24 lightweight sketches for fast ideation. Each image is individually reviewed by Midjourney's content safety filter, so some may be filtered out. Billing is per request, not per image, regardless of how many pass review.

Draft and Fast cost the same (1x); Draft is useful for lightweight exploration with up to 24 sketch images, while Fast is the default for production workflows. Use hd quality for sharper final assets when needed, and do not combine hd with draft.

When you submit a request, the API immediately returns a task ID. Poll /v1/tasks/{task_id} to check progress, or provide a callback_url to receive completion, failure, or cancellation events. Generated image links are valid for 30 days, so copy production results to your own storage when the task completes.
