Bitcoin Barometer — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is Bitcoin Barometer free to use?
Bitcoin Barometer is listed in our free catalogue, but it requires some form of authentication, so you will need to register before your first call. Providers frequently reserve higher limits and commercial use for paid plans.
Does Bitcoin Barometer need an API key?
Bitcoin Barometer requires some form of authentication. Check the provider's documentation for which scheme it expects.
Can I call Bitcoin Barometer from browser JavaScript?
