I want to integrate requesting Bitcoin data into a little project of mine. Therefore I am looking for an open API where I can request Bitcoin address data like balance and transactions. Google did not give me useful results. Any advices how to do without running an own Bitcoin node?

It is a common myth that Bitcoin is ruled by a majority of miners. This is not true. Bitcoin miners "vote" on the ordering of transactions, but that's all they do. They can't vote to change the network rules.

BlockCypher offers an API, as do many other blockchain explorers. If you take a look at the popular ones you'll probably find a few more that have one.

I agree, Bitgo is a pretty good service especially with BitGo Instant.. Everyone loves getting their balances upped instantly,
if they're using a Bitgo wallet as well that is.

blocktrail is easy to use and convinient, plus it is built for merchants as it have a well coded account system, you can easily create an account for each user and retrieve these informations quickly and without hustle.
In all cases, you will have to be confident with the usage of objects, wether you use PHP, NODEJS, JQUERY languages, these APIs always return objects, maybe sometimes arrays, and usually both at the same time so if you don't have a lot of experience in these languages, i advise you to ask for someone to help you, or at least, learn more about POO.

1.You don't have to run your own bitcoin node.Just a source for JSON data supporting multiple API calls.
2.You can either write your own JSON Rpc or use one of the existing from n number of sites listed above.
3.Addition to the above,I find this one quite faster https://www.blockcypher.com/dev/bitcoin/ in terms of handling multiple requests and calls per second.

Thanks, as said in the opening post, I just integrate a fast address balance check into my project. The project is a little community project. Nothing spectacular that has to be mentioned here Wink

I'm quite curious to see which of the APIs would be the fastest, actually. Have you considered trying each blockchain API in order to see which returns data the fastest? I suppose it doesn't matter too much for a community project, but it would be quite interesting to see anyways...

I don't understand why they are so restrictive about their API, but if you really need one to work with, use block.io, i like them because it is really easy to use, easy to generate and manage accounts, and they support bitcoin litecoin dogecoin.
I didn't tested the others but i plan to do it soon.
Talking about these APIs is there a website who tracks them ?

You do not understand ?

Because it costs them lots of money and ressources to maintain the API up, and to answer all the technical issues for the API users.
Why not just make an API like that one, for free and you will have an  idea of its complexity.


Block.io sucks.

Block.io sucks.

I know how complex it is, and i know how much ressources it consumes, but why other API providers do it without restriction ?
Block.io is a simple API who does the job, now for security considerations i didn't went too much in testing as i never had to use it in a production environment, i just know that it is accessible, easy to use, clear UI. And these are very appreciated qualities.

Block.io does not do any job, and their API is shit and not free, I used them for a year and it was a pain in the ass to work with them, they use STRIPE to bill their customers even when they pay with bitcoin, what the heck ?

I used them in development only, i won't pay for an api, especially when i don't need to use it, it is just that APIs are easy to use, and provides quick deployment.
It can be a pain for sure, especially if you need methods they can't provide.
Have you switched to annother API ?

Moved to Bitgo, but I decided to build my own solutions instead of relying on third parties, even payable ones.
