As some have already touched on, privacy is going to be a major roadblock, at least for our team in using this. Legally we can't send out any addresses, and I can't think of any ways around it for your queries at the moment.
Is there any way to do batch queries and receive aggregated data?
I know tracking companies were getting in a lot of trouble for just having hashed versions of emails sent out and a lot of users of those sites were very mad. I'd be pissed if my email was being sent along without my knowledge.
EDIT: Outside the privacy risk though this actually looks really neat and helpful. I'm assuming this is using the rapportive API or something very similar. Neat service, just too many privacy risks for me to use it.
Also, thanks for replying! Great to see you don't just avoid the privacy issues like others do at times.
I'd find this really useful if the REST API could return a JSON response to me instead of waiting for it to arrive in my inbox. I guess this isn't meant for integration into other applications?
I only tell you guys this because I want you to succeed and not get caught on a tiny mistake like this.
If they're not doing this, this is a great (but hard) way to almost guarantee 100% accuracy.
Are you planning on supporting HTTPS anytime soon?
