Every language your team writes.
Send a base64 image, describe what the captcha can contain, and read text. Check reliable before submitting. That's the whole integration.
curl -s https://captchaocr.allvoraz.com/v1/solve \
-H "Authorization: Bearer $CAPTCHA_API_KEY" \
-H 'Content-Type: application/json' \
-d "{\"image\": \"$(base64 < captcha.png | tr -d '\n')\", \"numeric\": true, \"length\": 6}"Numeric captchas, read exactly
Send numeric: true and the expected length. The decoder only considers digits and that many characters, and turns look-alikes (O → 0, l → 1, S → 5) into digits.
Hindi numbers and sums answered
“बयालीस − 6 = ?” and “14 + 9 = ?” come back as 36 and 23. Every Hindi number word from 0 to 100, with the expression returned so you can log it.
Wait for it, or fetch it later
/v1/solve returns the answer in ~25 ms. /v1/submit returns a task id at once and solves in the background; fetch it with /v1/result. No human queue either way.
Pay only for reliable answers
Every answer carries a confidence score. Unreadable images and low-confidence reads come back free.
Task API included
Prefer createTask / getTaskResult? The task-style endpoints (getBalance, reportIncorrect too) are built in, so existing integrations only change the host.
SDKs for 11 languages
Python, TypeScript, Go, Java, Kotlin, C#, PHP, Ruby, Rust, Swift and Dart, generated from one spec.
What it solves
The Hindi + numeric captcha solver
Indian government portals mostly use two kinds of captcha: Hindi-number captchas, a sum written with Hindi number words (बयालीस − 6 = ?), and numeric captchas, a code of digits (482915). Captcha OCR is a Hindi and numeric captcha solver in one API: send the image with {"math": true, "hindi": true} or {"numeric": true} and get the answer, ready to type, in about 25 ms. Arithmetic and alphanumeric captchas work too. See the Hindi captcha solver and the numeric captcha solver for accuracy and code.

Questions
What is a Hindi numeric captcha solver?+
An API that reads both kinds of captcha found on Indian government portals: Hindi-number captchas, where a sum is written with Hindi number words (बयालीस − 6 = ?, answer 36), and numeric captchas, a code of digits like 482915. Captcha OCR solves both in one API: send the image, get the answer in about 25 ms.
Can I submit a captcha and fetch the answer later?+
Yes. POST /v1/submit returns a task id immediately and solves the captcha in the background. GET /v1/result/{id} returns the answer when it's ready; add ?wait=10 to hold the request until then. Or call /v1/solve to get the answer in one request.
Can I get warned before my credits run out?+
Yes. Check your balance any time with GET /v1/balance, and set one low-balance alert with PUT /v1/alert: when your credits drop below your threshold, we POST your own JSON payload to your URL (Slack, your backend, anything with an HTTPS endpoint).
What does a credit buy?+
One reliable answer. If the response says reliable: false, or the image can't be decoded, it costs nothing. Refresh the captcha and try again.
How do I pay?+
Credit packs through Razorpay: UPI (Google Pay, PhonePe, Paytm, BHIM), credit and debit cards, netbanking and wallets. Credits never expire.
What if an answer was wrong?+
Report its id within 48 hours (POST /v1/report or reportIncorrect) and the credit comes back, up to 10% of a day's solves.
Which captchas does it solve?+
Hindi-number captchas (बयालीस − 6 = ?), numeric captchas (digit codes), arithmetic captchas (“14 + 9 = ?”) and alphanumeric text captchas. It doesn't solve interactive challenges like reCAPTCHA or hCaptcha.
Is there a Hindi captcha solver API?+
Yes. Send the image with math: true and hindi: true. The API reads the Hindi number word in Devanagari, does the sum and returns the answer in about 25 ms. It scored 100% on 175 live Hindi captchas it had never seen.
My code uses createTask / getTaskResult. Can I keep it?+
Yes. Point it at our host and send your key as clientKey. createTask returns a taskId at once, and getTaskResult is usually ready within 0.1 s.
