Same problem here, did you found a solution?

There should be another parameter `size_t dataLength` in the put method.

Why do you need a json response? https://blockchain.info/de/q/addressbalance/1NjMT4p8Chz6XEyhp8cXCzTwU5ZG3xjFfp Returns you the balance

See this page: https://en.bitcoin.it/wiki/Base58Check_encoding Supposedly this was done in order to avoid confusing a zero with an O and an O with an o

Your code looks correct although I did not run it. Instead of getting the private key in its Hex format you can also get it under its WIF format using...

What's the issue?

Mainly, it would just require replacing the sha256 hash function with the scrypt one

So either using this solution https://github.com/cmpscabral/cryptobits/tree/master/php/scrypt or this one https://github.com/DomBlack/php-scrypt

My mistake then, I believed they were using Scrypt to generate the address.
