Online address sweeper for BTC?

[EcuaMobi]

I developed this service for CAPTcoin:

https://api.captcoin.com/address/sweep/

What it does is asking for either an address or private key, then query the unspent outputs (from insight API) and create a transaction.

If the address was provided then it's only informative. If the private key was provided then the TX is actually signed and sent to the specified address(es).

It can also been used as a REST API: https://api.captcoin.com/address/#sweep

While technically this is quite simple (I could port it for BTC in a few of hours) I understand there would be a huge trust issue
and that's why I haven't even bothered. I know nobody would use it.

Is there a service like this provided by a trusted party?


Edit: Or does anyone have an idea to provide this service (preferably including an API) trustlessly?

Allowing people to host it themselves and the code to remain open to view (i.e. Github).

Create a new bc.i wallet, import private key, select "sweep" instead of plain import and send the coins their way. IIRC Mycelium allows this as well.

I meant an automatic service with an API like the one I describe on OP.

Well their API certainly allows it[1][2], but I dont know of an implemented solution.

Thanks!

But if I implement it myself using that then I'd be on the original trust problem hehe.

I was hoping for an extremely trusted provider to offer a complete service.

I think I'll drop the idea I had, at least for the moment.
