Yes! When you create a new account, you receive 250 word credits that can be directly used through the API.
The API endpoints allow you to access the UD functionality through your account. This means the word credits are deducted directly from your account, and the cost is identical to the web platform. You can visit your settings to see how many word credits you currently have, and the pricing page for more information on cost.
While there are no maximum usage limits, by default there is a rate limit of 3 requests per second, per IP address. If you need to process higher volumes of content, reach out to us at contact@undetectable.ai to raise your API limit.
We conform to the REST standard, which means all endpoints can be access through web requests. Check our documentation for more information specific to your use case.
Webhook integration and web callbacks are available to customers upon request. If you're looking to process high volumes of content and require webhook integration, reach out to us at contact@undetectable.ai.
