Pricing & Billing

uCaptcha uses a simple pay-as-you-go model. There are no subscriptions, no monthly fees, and no minimum commitments. You deposit funds, solve CAPTCHAs, and pay only for what you use.

Balance

Your account balance is denominated in USD. All task costs, deposits, and refunds are tracked in USD.

Check your current balance at any time:

• API: POST /getBalance with your clientKey
• Mini App: Balance is displayed on the dashboard

{
  "clientKey": "YOUR_API_KEY"
}

Response:

{
  "errorId": 0,
  "balance": 12.3456
}

Task Pricing

Pricing is dynamic and depends on several factors:

• Task type — Different CAPTCHA types have different base costs
• Provider used — Each provider has its own pricing for each task type
• Routing settings — Choosing the fastest provider may cost more than the cheapest

Typical Price Ranges (per 1,000 tasks)

CAPTCHA Type	Price Range
reCAPTCHA v2	$0.50 — $3.00
reCAPTCHA v3	$0.40 — $3.00
hCaptcha	$0.50 — $2.00
Turnstile	$0.30 — $2.00
Image captcha	$0.10 — $0.70

Note

These are approximate ranges. Actual costs depend on your routing configuration. Use the Cheapest routing preset to consistently hit the lower end of these ranges, or the Fastest preset if speed is more important than cost.

The exact cost per task is visible in your transaction history in the Mini App.

Deposit Methods

Telegram Stars

The fastest way to add funds. Available directly in the Telegram Mini App:

• Instant processing, no confirmation wait
• Purchase Stars through Telegram’s built-in payment system
• Stars are converted to USD balance at the current rate

Cryptocurrency (NOWPayments)

Pay with 50+ supported cryptocurrencies:

• Bitcoin (BTC)
• Ethereum (ETH)
• USDT (ERC-20, TRC-20, and other networks)
• Solana (SOL)
• Litecoin (LTC)
• And many more

Crypto deposits are processed automatically. Once the transaction receives sufficient confirmations on the blockchain, your balance is credited.

Tip

For the fastest crypto deposits, use USDT on the Tron (TRC-20) network. It has low fees and fast confirmation times.

Billing Flow

uCaptcha uses a pre-deduct and reconcile billing model to ensure you are never overcharged:

1. Pre-deduct — When you create a task, the estimated cost is deducted from your balance immediately. This reserves funds for the task.
2. Solve — The task is routed to a provider and solved.
3. Reconcile — Once the task completes, the actual provider cost is calculated. If the actual cost is less than the estimate, the difference is refunded to your balance.

This means:

• You always see sufficient balance reserved for active tasks
• You are charged the actual cost, not the estimate
• Over-estimates are automatically refunded

Failed Task Refunds

If a task fails (provider error, timeout, unsolvable CAPTCHA), you receive a full refund of the pre-deducted amount. You are never charged for tasks that do not return a valid solution.

Transaction Types

Your transaction history in the Mini App shows the following transaction types:

Type	Description
DEPOSIT	Funds added via Telegram Stars or cryptocurrency
TASK_DEDUCT	Initial cost reserved when a task is created
TASK_REFUND	Full refund for a failed or cancelled task
TASK_RECONCILE	Partial refund when actual cost is less than estimate
RECYCLE_CREDIT	Credit earned from key recycling (see below)

Key Recycling

Have leftover balance on a provider API key you no longer need? uCaptcha’s key recycling feature lets you convert that balance into uCaptcha credits:

1. Submit your unused provider API key through the Mini App
2. uCaptcha verifies the remaining balance on the provider
3. Your uCaptcha balance is credited with the equivalent USD amount (minus a small processing fee)

This works with API keys from any of our supported providers (CapSolver, 2Captcha, AntiCaptcha, CapMonster, Multibot).

Caution

Key recycling is a one-way operation. Once submitted, the provider key’s balance is transferred to your uCaptcha account. Make sure you no longer need the key before submitting it.

Cost Optimization Tips

• Use the Cheapest routing preset if solve speed is not critical. This routes every task to the lowest-cost provider.
• Use ProxyLess task variants whenever possible. Proxy tasks cost more due to additional provider overhead.
• Monitor your transaction history to identify which task types are costing the most and adjust routing accordingly.
• Bring your own keys for providers where you already have a balance. Tasks routed through your own provider keys are not billed by uCaptcha.
