BlockchainAPI is now a fully FREE Bitcoin API. We will continue to run this service free of charge for users to use our Bitcoin API.
You can now use BlockchainAPI for completely free of charge! 0% on all transactions! Happy bitcoining!
We've found that a post variable was being requested in the callbacks inside our docs and guide pages. Please remove any $_POST['invoice_id'] from your code as we do not send data for this post value. We've just made a full test on our system, which tested every single element, and can now confirm, EVERYTHING is working perfectly. Sorry for any inconvenience!
We have just completed an update which will hold huge masses of data in the future. We thought we'd do this now as we've seen a huge amount of users interact with BlockchainAPI.
