What Triggers CAPTCHA Challenges

Midjourney Discord bot may present CAPTCHA challenges when it detects unusual activity patterns:

  • Too many generations in a short period of time
  • Recently created Discord accounts are more likely to be challenged
  • Active connections from different geographical locations for the same account

How It Works

When a CAPTCHA is detected:

  1. The generation that triggered the CAPTCHA fails with a 596 error. The Midjourney account is locked and updated with an error message explaining that a CAPTCHA was detected. All subsequent API calls for this account will return 596 until the CAPTCHA solver unlocks the account or you manually resolve it via POST /account/channel/reset
  2. You receive a notification email immediately
  3. The CAPTCHA solver is triggered automatically
  4. A second email is sent either:
    • Confirming the solver successfully cleared the CAPTCHA and unlocked the account, or
    • Asking you to solve it manually (rare cases)

The entire process takes 60-90 seconds. Based on our in-house testing, we expect the success rate to be close to 100%.

👉 We strongly recommend setting your Discord account language to English. Our CAPTCHA solver is primarily tested with English and may not work as reliably with other languages.

Important: Preventing Excessive CAPTCHAs

While our CAPTCHA solver will handle challenges automatically, frequent CAPTCHAs indicate you are pushing the account too hard. Continued aggressive usage patterns may lead to permanent account bans by Discord/Midjourney.

To avoid problems:

Add More Accounts

If you’re hitting CAPTCHAs frequently, consider adding more Midjourney accounts to spread the load. Our API supports multiple accounts with automatic load balancing.

Handle 596 Errors Gracefully

When you receive a 596 error response, it indicates account issues (often CAPTCHA-related). Consider a 10-15 minute cooloff period before retrying. If you have multiple accounts configured, our load balancer will automatically switch to a different one.

  • Spread load across multiple accounts
  • Add random delays between generations
  • If you run mostly --relax generations, execute --fast once in a while

No Additional Cost

The CAPTCHA solver is included free with your useapi.net subscription. There are no per-solve charges or hidden fees.
