Does Midjourney have an official API?

Not publicly, as at the review date on this page. Its terms of service prohibit using automated tools to access the service or generate assets, which is also why the third-party "Midjourney API" services you will find are unofficial. An enterprise offering has been discussed but not released — check Midjourney’s own site for the current position before deciding.

Can I get the Midjourney look from this API?

Not identically, and anyone claiming otherwise is selling something. Midjourney’s aesthetic comes from its own model. What you get here is a curated set of open-weight checkpoints across photoreal, anime and comic styles that you can steer yourself, plus LoRAs and trained characters for consistency.

Are prompts moderated the same way?

No. There is no keyword filter and no contextual moderation model on your prompt. One gate is enforced — sexual content involving minors — and it returns 422 for that request without any account consequence.

Can I resell generations to my own users?

Yes. Building a product on top of the API and charging your own users for it is the intended use, subject to the Acceptable Use Policy.

FastGen Cloud vs Midjourney

Midjourney is a remarkable image generator and, for developers, a frustrating one: there is still no official public API, its terms prohibit automated access to the service, and the third-party "Midjourney APIs" you will find are unofficial wrappers around an interface that was never meant to be automated. If you need something you can build a product on, that is the comparison that matters.

Side by side

Dimension	FastGen Cloud	Midjourney
API access	A documented REST API with keys issued from the console. Building products on it is the intended use.	No official public API. The terms of service state you may not use automated tools to access, interact with, or generate assets through the service.
Interface	HTTP from your backend.	A Discord bot and the Midjourney web app.
Third-party wrappers	Not applicable — the first-party API is the product.	Several unofficial services resell access. They sit outside the terms of service and can stop working without notice.
Prompt handling	Verbatim. Nothing injected, nothing rewritten, no rating tags appended.	Prompts are screened by keyword filters plus a contextual moderation model before rendering.
Content rules	One minor-safety gate at the prompt; everything above that floor is your policy.	Community guidelines require broadly PG-13 content: no adult content, no gore.
What a violation does	422 on that single gate, scoped to the request. Nothing is charged and no automatic account action is taken.	A flagged job is typically dropped, and repeated violations escalate to warnings, temporary bans and permanent bans.
Identity from a photo	A Face ID endpoint from one photo, plus character training referenced by id.	Character-reference features exist in the app; there is no documented programmatic contract for them.
Payment model	Prepaid balance, debited per output at submit, auto-refunded when a job fails.	Monthly subscription tiers with GPU time allowances.

When Midjourney is the better choice

For a human making images by hand, the honest answer is that it is often the better tool and no API can substitute for taste that is baked into the model.

You are producing work by hand rather than generating programmatically
Its house aesthetic is what you want, which is a real and hard-to-replicate thing
Discord or the web app is a workflow your team already likes
You have no need to embed generation in your own product

When you need an actual API

The moment generation has to happen inside your product — triggered by your users, billed to your account, returned to your UI — an interface designed for humans in a chat client stops being viable. Unofficial wrappers bridge the gap at the cost of depending on something that breaks when the upstream changes and that you are not permitted to use.

You are generating on behalf of end users and need per-request accounting
You need a signed webhook, retries, idempotency and a job id you can reconcile against
You need terms that permit programmatic access and reselling generations to your own users
You need a predictable unit cost per image rather than a shared subscription allowance
Your product serves adults and a PG-13 content rule is the blocker

What migrating actually involves

The shape is the same everywhere: authenticate, submit a job, wait for a callback, download the output. In practice a migration is one client module and a model-name mapping.

submit + wait

const res = await fetch("https://api.fastgencloud.com/v1/images/generations", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${process.env.FASTGEN_API_KEY}`,
    "Content-Type": "application/json",
    "Idempotency-Key": requestId,
  },
  body: JSON.stringify({ model: "general-image", prompt, size: "1024x1024" }),
});
const job = await res.json();          // 202 → { id, status: "queued" }

// then either poll GET /v1/jobs/{id}, or pass webhook_url and get a signed callback

How billing works here

Money is a prepaid balance in your account. You top it up with a card, each job debits it at submit time, and a failed job is refunded automatically — there is no invoice at the end of the month and no way to run up a bill you did not intend.

Rates are per image or per second of video, published on the pricing page. Images above 1 megapixel bill pro rata by pixel count. Outputs are retained for up to 7 days.
