Security Scan API

Hi,

 

In our application, there is one functionality 'uploading files'. while uploading files client has asked to scan the files programatically before uploading to the server. we tried with metadefender api for scanning, but it's pricing too high for commercial use.Can any one suggest which online security scan api would be good and economical.If any one has used such feature in any of your projects, please send me the sample code too. 

 

 

Thanks in advance,

Hema
