APIs to receive and send SMS messages to users?

[kiran]

I'm building an interactive SMS app and looking for simple HTTP APIs
to send messages to and receive messages from users.
- Does twitter support such APIs to interact with twitter users (i
didn't find any documentation on these)?
- If not, where can i find free APIs that don't charge per message
(the SMS aggregators/carriers charge a per-message fee, expensive for
garage startups).

Typically, these APIs are offered on a shared short-code, and the
mobile-originated messages would start with an app prefix (e.g. APP1)
so the API platform would know which application to call.

thanks

Twitter does not provide direct SMS interaction with users. You could use direct messages but the user may not have SMS notifications turned on.

If you check out Wikipedia they have a list of gateways for email to SMS. For example you send an email to <phonenumber>@sms.att.net (not actually ATT's address) and it shows up on the phone. Nice and cheap but not the carriers first priority.

You can allso try this thing called Google. I've heard of a number of startus that provide APIs to send SMSs and such they are probably only going to be free if they are add supported.
