don't ignore the fact they've got the shittiest of the shittiest api's ever.
Their shit doesn't close connections properly, so if you make a lot of captcha it will eventually exhaust all your ports.
A month ago I tried to starta program on my dedi and it just wouldn't start. Kept crashing.
Only later on have I found out that I have like 8k opened connections to DBC.
Personally I use antigate.com and use decaptcher as backup.
Cheapest bang for the buck.
I've got level 6 account so all my captchas cost only 0,8c (spent a lot of k$ there), and additionally if you solve I think 20k per day they automatically appoint a 10% discount on top of that, so they charge 0.7$ per 1000.
they have their downsides though.
Overloading is biggest one. Their servers are almost ALL the time at 90%+ load and often at 100% so small overbidding is needed (usually around 1.1- 1.2$).
another one is their purchase policy. you do not get credited automatically like you do in decaptcher, but instead receive a 12 digit alphanumeric code to your mail, which you enter in the CP to refill account.
Smallest value is 10$, biggest is 50$, so when you're ordering 500$ worth of captcha you'll go nuts entering your info on avangate (their payment processor) again and again.
It's still half cheaper than decaptcher so \o/ for that.
Oh, don't know about DBC, but I know antigate has some cool optional features you can use.
Like:
- specifying that captcha is numbers only. worker has to enter ONLY numbers or it won't accept his input
- specifying that captcha has 2 or more words, so typers won't enter thisisawesome, 3 words as 1.
- specifying that captcha is a russian word. You can send it to a russian worker (very important for cyrilyc captchas).
- specifying that captcha should be summed up. VERY useful for mathematical captchas.
- then there is statistics that show you all the images you sent, images solved, complaint button under each image. ALL the captcha images are stored, so you can see what you were solving 2 weeks ago).
- there's the limit per IP feature, so only allowed ip's will be able to spend credits with your account
- then there's a security token. You do not enter username/pass in your program to solve it, but instead only use that in their CP. For your program you get a 13 digit alphanumeric number "w54b54yv45754bv45v" like this, that you input in your program.
This makes sure you cant get hacked by having your credentials stolen from a decrypted program exe.
