Dota.

Your set is actually worth $1,67. That's not even a key.

You could try selling the pieces on steam market or trade it for keys on dota-trade.com / dota2lounge.com or whatever ( google is your friend) but there are no websites like for tf2 where you can trade it with bots for keys/credits ...

I haven't heard of such site. Maybe there are sites that offer automated bots that take your items and give you some 'point/currency' on their site but you probably won't find a service that will automatically change your dota2 items into tf2 keys...

Afaik there is no site like this. Also items are worth much less than store prices, it's like saying: Hey my Alice Madness Returns is worth 50€. Also it's Diretide, so all kind of items and sets droped their prices.

What you probably want is something like this:

Yeah, not items to key, but items to gold then to key, if you want that.
But please don't forget, the same as with steam game trades, items worth a lot less too, while trading.
Or maybe you want some auction? http://dota2bid.com/

(Also please note, I never used these sites, and I prefer human traders. :) )

Sell the item in steam market, use the money you get, buy keys... duh?

Waits for the "I got scammed thread."

I give you common for that worthless set.

Yes this is sarcasm.
