​
Concurrency Limits

Each user has a maximum number of concurrent tasks (threads) they can run simultaneously. The limit depends on your plan or package. If you exceed your thread limit, the API returns ERROR_THREAD_THRESHOLD_EXCEEDED.

​
Package Quotas

Package-based keys (PKG-) have quotas depending on the package type:
Package TypeQuota
unlimitedNo limit during subscription
dailyFixed solves per day (resets at midnight UTC)
hourlyFixed solves per hour (resets each hour)
Exceeding your quota returns ERROR_RATE_LIMIT_EXCEEDED.

​
Balance Protection

For balance-based keys (FUN-):
  • Each solve costs **0.00075∗∗(0.00075** (0.75 per 1,000)
  • Balance is deducted when the task starts
  • Failed tasks are automatically refunded
  • Use POST /getBalance to check your current balance

​
Handling Rate Limit Errors

When you hit a rate limit, implement exponential backoff: 
import time
import requests

def create_task_with_retry(client_key, task, max_retries=5):
    for attempt in range(max_retries):
        resp = requests.post("https://api.funbypass.com/createTask", json={
            "clientKey": client_key,
            "task": task
        })
        data = resp.json()

        if data.get("errorCode") == "ERROR_THREAD_THRESHOLD_EXCEEDED":
            wait = 2 ** attempt
            time.sleep(wait)
            continue

        return data

    raise Exception("Max retries exceeded")

Service Availability

If the service is temporarily disabled, all task creation requests return ERROR_SERVICE_UNAVALIABLE. Monitor the status page for real-time availability.
