Error Messages

While using smartClassifyPlus API there could be some error messages, that are done for file validation checking:

Error Message	Description
Please send the correct input file format!	The file format is not (PNG,JPG) or (PDF)
Please send a file that doesn’t exceed the size limit!	The file size is more than the allowed limit (number)
Please make sure that your file doesn’t contain any suspicious malware data!	The file contains suspicious data, then security check system warns you
You have ran out of Laigos, renew your subscription to continue using Laigo APIs!	All of your Laigos are used, please renew your subscription

Example (step by step)

1.First you need to have a document sample that you want to use with smartClassifyPlus. It can be any document type such as: invoice, receipt, letter, email etc. For e.g you can use the invoice advertisement below:

2.Inorder to use our smartClassifyPlus tool you need to have an API key which can be generated from here.

If you don’t have an account, first you need to set up your account then you can generate the API key. Create an account here.

3. After you have generated your API key, then you can use smartClassifyPlus in any popular programming language, where you can find the code snippets here.

4. Run your code. You will receive a JSON response with the invoice details. See expected responses here.

its capabilities and limitations in performance, including the degrees of accuracy for specific persons or groups of persons on which the system is intended to be used and the overall expected level of accuracy in relation to its intended purpose;

Especially, if the quality of the image and the resolution is bad, text can be missed or misinterpreted in a wrong language. This appears also, if the orientation of the picture/PDF is not aligned to the orientation of the text. With this, it is possible that documents are classified not properly.

The overall accuracy is independent of specific persons or groups of persons which the system is intended to be used.

the foreseeable unintended outcomes and sources of risks to health and safety, fundamental rights and discrimination in view of the intended purpose of the AI system;

No risk to health and safety expected. Fundamental rights are respected and no discrimination of certain individuals considered.
