Hi anybody can guide me to withdraw BitCrystals from http://www.spellsofgenesis.com/ to my Counterwallet?

See earlier comments, they are currently working on a solution for this.
For now you can buy them on exchanges and swapbots.

I created a swapbot to sell some of my spare Cards.
Currently it still holds 3x RIPPLECARD, I plan to put some other "hard" to get cards in there during the next week.
I will also sell 1 FDCARD through Auction or Swapbot later next week.

As far as I know Rabobank is still the most hostile towards bitcoin.

You should have less problems with ING and or ABN AMRO, however this could change any day.

You can use https://bitonic.nl/ with Ideal or https://www.clevercoin.com/nl with other payment methods, or use https://localbitcoins.com/ for a cash solution.
We also have https://www.happycoins.com/nl and https://anycoindirect.eu/ which are all serious companies.

If you want "Fresh" bitcoins you can have a look at our Mint:
https://www.blocktrail.com/mint/

We accept only bitcoin at this time though.

If you want to start a bitcoin company, I suggest you contact the https://bitcoinembassy.nl/ or http://stichtingbitcoin.nl/. If you want to exchange bitcoin for FIAT at your compnay I suggest you contact "de Nederlandse verenigde bitcoinbedrijven. Can't find the info though.

Last night the winners of our hackaton provided some updates about their project https://github.com/baleato/bitcoin-hackathon
After they gave their presentation there was another guy who also had a similiar idea and already had a working prototype: https://bitcointalk.org/index.php?topic=94674.0

It is slightly off-topic though, but I think you find this very interesting.

Re: List of Bitcoin blockchain APIs
by
Tjopper
on 02/02/2015, 17:57:46 UTC
i. https://blockchain.info/api/api_send

ii. https://blockchain.info/api/api_receive

If you are offering similar alternative, can you please point me to the specific links on https://www.blocktrail.com/api/docs ? Conversion to any FIAT is not the requirement. bc.i does not offer it either.

The main issue with blockchain.info (and many other APIs) is that they have direct access to your coins. It's originally a webwallet where your password never leaves your browser, but their API requires you to provide their server with the password and thus gives them custody of your coins.
You'll never need to do that with BlockTrail because the transactions are created and signed on the client side using the SDK, and are then co-signed and broadcasted via BlockTrail.

The blockchain.info receive API actually makes the bitcoins go to their own address first before the coins come to you, again, giving them full custody of your coins.
This is done for various technical reasons and are considered bad practice nowadays - the main reason being that you can't monitor your own addresses for transactions and that they have a max amount of addresses (which is because you need to backup every private key for each address).

The Blocktrail Wallet API is a HD Wallet, so you can have unlimited addresses, create a new one every time you need to receive coins (as best practices dictate) and because of the HD 'magic' you never even need to create new backups.
And we also have 'webhooks' which allow you to get notifications ( we send data to your server using a HTTP POST ) when your addresses receive transactions.

Initialize SDK
Code:
$this->client  = new BlocktrailSDK($yourAPIKey, $yourAPISecret, "BTC", $testnetTrueOrFalse));


Create a wallet
Code:
list($wallet, $primaryMnemonic, $backupMnemonic, $blocktrailPublicKeys) = $this->client->createNewWallet($yourWalletID, $yourWalletPassword);

Setup transaction notifications
Code:
$wallet->setupWebhook('https://example.com/receive/wallet/transactions/notifications');

Receive a transaction
Code:
$wallet = $this->client->initWallet($yourWalletID, $yourWalletPassword);
$address = $wallet->getNewAddress();
you'll be automatically subscribed to notifications on these new addresses

Send a transaction
Code:
$wallet = $this->$client->initWallet($yourWalletID, $yourWalletPassword);
$txHash = $wallet->pay([$bitcoinAddress1 => $amount1, $bitcoinAddress2 => $amount2, /* .... */]);

Get wallet balance
Code:
$wallet = $this->client->initWallet($yourWalletID, yourWalletPassword);
list($confirmedBalance, $unconfirmedBalance) = $wallet->getBalance();

That's great! Blocktrail is becoming better day by day. Just a simple question, using PHP, can this be used for faucets?

Yes it can be used for a faucet, we actually used it for our own faucet.

Do you have any plan to include a "broadcast raw transaction" function on blocktrail like the one on blockchain.info and blockr.io?

We are still investigating this, maybe in the future.

If you want fast response on your questions, please send us an e-mail or use our support system.
Thanks for the feedback!

Jop

1. Do you have any plan to open the source code like insight.is ?

2. Any plan to provide something equivalent to blockchain.info's send & receive API ?

1. We contributed to various bitcoin related projects in the process of making our API and SDK and our SDKs are open source, but we're not planning to open source our server architecture
2. We now offer Multisignature + HD capabilities through our "wallet API". Im not sure if this answers your question though.

I have got a list of transactions for an address back using your api.  Now, i want to colour code them with green=incoming and red = outgoing?  How do i know which is which?  Everything seems to be positive.

Can you confirm to me that our CTO helped you out fixing this issue ?

Thanks, that was exactly what I was looking for (but with search disabled...)

Actually, after a second glance, not really. Smiley The focus of the other thread is block explorers, not the discussions of APIs.
So it seems that most people report their favorite block explorer for occasional manual use,
rather programmatically usable APIs that support a bigger feature set. Most of the sites listed
don't have an API.

Try to list those especially offering bitcoin send/receive API. AFAIK none still offers it as good as blockchain.info, though it is difficult to offer a send API for those, who do not have a wallet service.

Can I challenge you to try our API and see if you still think bc.info is the best ?
Im from the https://www.blocktrail.com/ team, if you need any help I can get our team to help you with the integration.

I dint say bc.info is great in terms of normal blockchain API. I said it in terms of 2 specific functions required by merchants... the send & receive API. bc.info is becoming monopoly in providing these 2 specific service, which I think is bad.

Sorry for my miss understanding there,
We do offer send and receive but only for BTC not a conversion to dollars or euro, is this where you are looking for ?
