I'm gathering a list of Bitcoin / Blockchain APIs. I mean web (REST) APIs that allow you to do basic blockchain queries through http(s) API calls, such as: getting the balance on an address, getting a list of transactions from or to an address, getting the details (inputs and outputs) for a transaction, et cetera.

I'm familiar with blocktrail.com, blockcypher.com, blockchain.info, and blockr.io, but I remember having seen others in the past. Any more?

  • It would be even better if there were links to the API documentation somewhere... – David Manheim Dec 30 '15 at 20:59

Insight by bitpay:

https://insight.bitpay.com/

Block Explorer:

https://blockexplorer.com/

Bitcoin Chain:

https://bitcoinchain.com/block_explorer

There are many more in development, but these are ones I could find that you didn't list.

  • Thanks, from what I understand, insights is both a web explorer as well as an API. Very useful addition. I forgot about blockexplorer.com, they used to be different but it seems like a copy of insight / bitcore now? As for bitcoinchain.com, is that just a web explorer or is there also an API in there? (I couldn't find it?) – RocketNuts Oct 31 '15 at 21:16
  • blockexplorer at least used to use their own code. You can run your own with abe: github.com/blockcypher/explorer. bitcoinchain.com, I haven't used, but it wouldn't surprise me to know there's no API there. – Jimmy Song Nov 3 '15 at 2:52
  • You can also add following to the list: blockonomics.co, smartbit.com.au, biteasy.com – dark knight Dec 1 '15 at 5:26
