# Bring Your Own Account (BYOK)
> Host your own Midjourney subscription: fast-mode image tasks run on your own account for a flat monthly credit rent, with zero per-task platform credits.
## What is BYOK?
BYOK lets you bind your own Discord account (with an active paid Midjourney subscription) to your Legnext account. While bound:
* **Fast-mode image tasks** — `imagine`, `variation`, `upscale`, `reroll`, `blend`, `describe` — execute on **your own Midjourney account** and consume **no platform credits** per task.
* **Everything else** — video and edit/enhance tools — keeps running on the platform pool and is billed per task as usual. Your API calls don't change either way.
* **Rent**: BYOK costs **20,000 credits/month** ($20 at $1 = 1,000 credits), charged from your credit balance. The first month is charged when you bind; renewals are attempted automatically starting 3 days before each due date.
## Before you bind
1. The Discord account has an **active paid Midjourney subscription**.
2. The account has **sent at least one DM to the Midjourney bot** (Discord requires an existing DM channel for the engine to deliver commands).
3. You have the account's **Discord token**: log in to discord.com in your browser → DevTools (F12) → Network → filter by `api` → click any request → copy the `Authorization` request header value.
A Discord token grants **full control** of the Discord account — never share it with anyone. Automating a user account may violate Discord's Terms of Service and can lead to the account being **permanently banned**. We strongly recommend using a dedicated account rather than your main one.
## Bind, manage, unbind
Everything lives in the dashboard under **My MJ Account** (`/app/byok`):
* **Bind**: paste the Discord token. Your balance must cover the first month's rent.
* **Status**: the page shows the live state of your account (active, session expired, fast hours exhausted, etc.) pulled from the engine in real time, including operator guidance when something is wrong.
* **Update token**: if Discord invalidates your session (status `cookie_expired`), paste a fresh token to recover — the account resumes automatically.
* **Unbind**: returns you to pure pay-as-you-go. Rent already charged is not refunded; rebinding starts a new billing cycle.
## Multiple accounts (pool)
You can bind **more than one Midjourney account**. Each bound account is billed its own **20,000 credits/month** — rent scales linearly per account.
* Tasks are routed to the **least-busy healthy account** in your pool (engine status `active` and rent current). If no account is usable, fast-mode image tasks fail with a 400 that names the most actionable fix (top up for a rent-due account, or update the token of an expired one) — they never silently fall back to platform-credit billing.
* Your effective fast-image concurrency scales with the pool: `max(6, min(account concurrency limit, 3 × usable accounts))`.
## Billing states
| State | What it means | What to do |
| ------------- | ---------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------ |
| Active | Rent paid, tasks pinned to your account | — |
| Rent due soon | Renewal failed (balance too low) inside the 3-day window before the due date | Top up; renewal retries hourly |
| Suspended | Due date passed without a successful charge | Tasks are paused (400 "rent due"); your binding is kept — top up and it resumes automatically within an hour |
## Failure states of your Midjourney account
| Engine status | Meaning | Recovery |
| ------------------- | ------------------------------------------------------------------------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------- |
| `cookie_expired` | Discord invalidated the login session (401 on all endpoints) | Paste a fresh token on the BYOK page |
| `captcha_required` | Discord asks for a captcha | Log in to discord.com, complete verification, then update the token |
| `credits_exhausted` | Your Midjourney fast hours are spent | Renew your MJ subscription or wait for the next billing cycle |
| `banned` | Account banned by Discord/Midjourney (permanent) | Unbind and bind a different account |
| `disabled` | Token works but Midjourney refuses it (e.g. app authorization revoked, Discord code 20064) | Follow the remedy shown on the BYOK page — typically someone must sign in and re-authorize the Midjourney app; a new token alone will not help |
While your account is in any non-active state, fast-mode image tasks are rejected with a clear 400 — they never silently fall back to platform-credit billing.
## FAQ
No. Endpoints, parameters, and your API key stay the same. Binding only changes where fast-mode image tasks execute and how they're billed.
Tasks queue engine-side and wait for your account (up to 1 hour). They are never moved to another account or the platform pool.
Yes. Each account is billed 20,000 credits/month separately, and fast-mode image tasks are routed to the least-busy healthy account in your pool. See "Multiple accounts (pool)" above.
Yes for everything outside the BYOK domain: video and edit tools bill normally from your credit balance. Fast-mode image tasks always run on your own account while bound — unbind if you want them back on the pool.
