Top-ups from $30, in USDT on TRON (TRC20). No subscription, no monthly fee.
Three calls
Every type works the same way. Create a task, poll until it is ready, read the answer.
1. POST /createTask
Send the CAPTCHA parameters. You get a task id at once.
{"clientKey":"…","task":{…}} {"errorId":0,"taskId":18342}2. POST /getTaskResult
Poll every 5 seconds until status is ready. Failed tasks return an error and are refunded.
{"clientKey":"…","taskId":18342} {"status":"ready","solution":{…}}3. POST /getBalance
Check the balance before large batches.
{"clientKey":"…"} {"errorId":0,"balance":42.5}
Keep your code. Change two lines.
Point your solver library or your own client at unlock-api.com and use your key from the account page. Task names, parameters, ids and error names stay the same, so retries and error handling you already wrote keep working.
Works with both formats: in.php and res.php (form fields, plain or JSON replies) and createTask, getTaskResult, getBalance (JSON).
- API_URL = "https://your-current-solver" - API_KEY = "YOUR_CURRENT_KEY" + API_URL = "https://unlock-api.com" + API_KEY = "YOUR_UNLOCK_API_KEY" # everything else stays the same
Your dashboard
API key, balance, every task with its status and cost, and top-ups in one place.
Rules you can rely on
Unsolved means free
A task that fails or runs past 5 minutes is refunded to your balance automatically, with the error name in the reply.
Refused means free
Requests refused with an error, such as a wrong key, low balance or no capacity, are never charged.
Request data deleted right away
Images, proxies and request details are deleted when a task finishes. Type, status, cost and answer stay in your history.
Fixed limits
1,200 requests per minute per account, result checks included. Tasks time out after 5 minutes.
Questions
Do I need to change my code?
Only the address and the key. The API accepts the same in.php and res.php fields and the same createTask and getTaskResult JSON, and answers in the same format with the same error names.
When am I charged?
When the task is created. If it fails or is not solved within 5 minutes, the full charge goes back to your balance automatically.
How do I add funds?
With USDT on TRON (TRC20). Each top-up gets its own address and an exact amount, and the balance updates after the network confirms the transfer.
How do I sign up?
Click Get an API key. You get an account token: save it, because it is the only way to sign in. Your API key is created at the same time.
Can I get a refund of my balance?
Balance is used for tasks and is not paid back to a wallet. Charges for failed tasks always return to the balance.
Which CAPTCHAs are not supported?
Types that are not on the price list are refused with ERROR_TASK_NOT_SUPPORTED and are not charged.
Get your API key in a few seconds
Sign up with one token, no password. Your API key appears on the account page right away.
