Price

$5 per month (paid in rupees by JazzCash, Easypaisa or bank transfer, about Rs 1,400). Admin accounts get API access for free. Each key can generate up to 500 captions a day.

Get your API key

1. Create a free account or log in.
2. Open Account and find the Lafzaly API card.
3. Click Get API access, pay, and enter your transaction ID. Access is switched on after we check the payment.
4. Click Create my key. Copy it right away, because it is shown only once.
