A post on the Make.com community forum lays out the whole problem in two sentences.
Blocked for using automation and third-party tools — that's the notice one user received, ban ID attached, after building a workflow around a paid service called UserAPI.ai.
The account that got blocked was tied to a real Midjourney subscription the user had been using for months.
I don't use Midjourney or any of these third-party tools myself, so this is built from Midjourney's own published policies, its terms of service, and public reports from people who've run into this. What makes this issue worth untangling isn't that Midjourney is vague about its rules — it's the opposite. The confusion comes from an entire commercial ecosystem selling access to something Midjourney has said, repeatedly and explicitly, it does not offer.
Midjourney Has Never Had a Public API, and Says So Plainly
The twist in this story: Midjourney isn't the vague one here. Its rules on automation have been public and explicit since 2022. The confusion comes from elsewhere.
Midjourney's own Community Guidelines state the policy in unambiguous terms: with a few rare, explicitly granted exceptions, the company does not provide an API, does not provide third-party apps or scripts, and automating interactions with the service is strictly prohibited under its Terms of Service. That's not a footnote buried in a EULA — it's rule four of four in the guidelines' top-level list, sitting right alongside "be kind" and "keep content safe for work."
The terms of service go further, stating plainly that automated tools may not be used to access, interact with, or generate assets through the service at all. This has been Midjourney's position since it launched in 2022, and as of mid-2026 it remains unchanged: official access is still limited to the Discord bot and the midjourney.com web app, on subscriptions running roughly $10 to $120 a month, with no developer endpoint, no API key, and no published per-image pricing for programmatic use.
So the rule itself isn't the confusing part. What's confusing is what happens next.

The Market Selling You Around the Rule
Search "Midjourney API" and you won't find one from Midjourney. You'll find a cluster of third-party services that advertise exactly that: API-style, programmatic access to Midjourney image generation, built to plug into tools like Zapier, Make, or a custom script.
Names that show up in this space:
PiAPI
useapi.net
ImaginePro
UserAPI.ai
Apify actors
Here's the part that catches people off guard: these services don't have special access Midjourney granted them. Under the hood, they work by automating a real Midjourney account — either puppeting a browser session or scripting interactions with the Discord bot — using credentials tied to an actual subscriber. Some ask you to connect your own account; others run a pool of accounts behind the scenes. Either way, the underlying mechanism is exactly the automated access Midjourney's terms prohibit. One developer maintaining an open-source Midjourney automation tool added a blunt warning to their own project after running into this personally: using it to access Midjourney could get an account blocked or permanently banned, a lesson they say they learned the hard way.
None of this means every user of these services understands the risk going in. A checkout page selling "Midjourney API access" for a monthly fee doesn't necessarily spell out that what you're buying is a terms-of-service violation running on borrowed or pooled account credentials — and the ban, when it lands, shows up on the Midjourney account, not the third-party service that sold the access.
Why Midjourney Doesn't Just Build an Official API
It's worth asking why this gap exists at all, since plenty of competing image generators — Stability AI's models, Black Forest Labs' Flux, Google's offerings — do offer official, developer-facing APIs with published pricing. Midjourney hasn't explained this decision in detail, but a few things are consistent with the choice: the product has always centered on the Discord community and web app as a shared, curated space rather than a headless generation engine, and opening a metered API would mean supporting a very different kind of usage — bulk, unattended, commercial-scale generation — that the current subscription and moderation model wasn't built around. Whether that's primarily a moderation concern, a cost-control decision, or a deliberate product-identity choice isn't publicly detailed by the company, but the result is the same either way: legitimate automated access simply doesn't exist, and demand for it hasn't gone away just because the option hasn't been built.
What "No Warning" Actually Means Here
Midjourney's general enforcement process, as described in its own guidelines, allows for a warning or a time-out before an outright block for most rule violations. But the automation-specific rule is written differently: it states plainly that accounts who do not comply "may be blocked," without describing an escalation step first. Public reports back this up — the Make.com forum case above describes a direct block with a ban ID and a link to an appeal form, not a prior warning about the specific automation that triggered it. For someone whose workflow has been running for weeks without incident, the practical experience is exactly the "banned out of nowhere" feeling the original complaint suggests, even though the underlying rule was never actually hidden.
What Actually Helps
If you're already blocked, Midjourney does provide an appeal path — a form linked directly in the ban notification — though as with most appeals processes across these platforms, a submission doesn't guarantee reinstatement, and public reports of outcomes are mixed at best.
The more useful move is prevention, and it comes down to one question worth asking before building any workflow around a "Midjourney API": is this Midjourney's own official offering, or a third party automating an account on your behalf? If it's the latter, the account tied to that automation is genuinely at risk, regardless of how long it's run without a problem so far.
For anyone who specifically needs Midjourney's particular visual style inside an automated pipeline, there isn't currently a risk-free way to get it programmatically — that capability simply isn't for sale from Midjourney itself. The lower-risk path is choosing a model with a genuine official API instead: Flux, Stable Diffusion (through any of its many hosts), Recraft, and other current-generation image models all offer documented, developer-facing endpoints without the account-ban exposure, even if matching Midjourney's exact aesthetic takes some prompt adjustment.
The Broader Point
The lesson generalizes past this one tool. When a platform explicitly states it has no public API, any product marketed as an API for that platform is, by definition, doing something the platform hasn't authorized — and the risk of that arrangement typically lands on the customer's account, not the vendor selling access to it. That's worth checking before any subscription gets wired into a business workflow, especially one a solo creator or small team is depending on to keep running without warning.
This piece is based on Midjourney's official Community Guidelines and Terms of Service (current as of mid-2026), public forum reports from users who've experienced automation-related blocks, and documentation from third-party services describing how their tools access Midjourney. Enforcement policies and the third-party tool landscape both shift over time, so it's worth checking Midjourney's current guidelines directly before assuming any of the above is still accurate.
