I make a JSON call to
This is a free api with a request limit.
I have just received my api_code via email. This is blockchain.info's example of how to use it
Once approved the API Code can be passed to all requests in the "api_code" parameter e.g. https://blockchain.info?api_code=$your_code
I am guessing that they mean with PHP (because of the dollar sign) as when I type into my address bar
The data does not any look different when I use the api code with the dollar
Though I am unsure of how to tell what is the correct way as I can access this free api with and without an api code (with a request limit). How do I tell if I am adding it correctly?
