List of Bitcoin blockchain APIs

[arnuschky]

Is there any API offered by blocktrail.com that allows to Push a Tx, e.g. https://blockchain.info/pushtx ?

Others do offer this service: Hello Block, chain.com, toshi...
 (Note that the "push" functionality might have different names such as "propagate", "publish", etc)

"Blockr", a block-explorer service, also offers this functionality even tough they don't have an API: https://btc.blockr.io/tx/push

Why isn't BlockTrail under "High-level wallet APIs"? They have a wallet function and everything Blockchain.info has.

As far as I can see, they have a data API just like everyone else. Actually, I thought about removing the "high-level wallet API". I fail to see the advantage over just having your own wallet, and using one of the many data APIs to process payments.

Not sure if this would fall under High-level wallet API but Block.io seems to be another service offering some APIs. I haven't looked at the docs yet but heard about them a couple times in the past few days.

what exactly do these limits at BlockTrail mean?

Code:

1 request per second
86,400 requests per day
Burst Capabilities
2 per second
Dedicated Email Support

Does it mean, that my application is only allowed to check for one transaction in one second?

Assumed i have an online shop, and 4 customers send 4 payments at the same time, then i will be able to check only for the confirmation of one payment out of 4 at once?

What are the costs for the "Pro" package?

No. You can only make one request per second. Please check their page for knowing the rates.

A request is a http request, that means, a single call to their API per second. Your example might still work if they allow to check multiple addresses etc in a single request. But yes, most likely you'll need the pro package.

BTW, Hello block is not available anymore. Unfortunately, because they were the only ones apart from Toshi that passed my list-of-unspents test. :\

I removed them from the list.

[arnuschky]

Added block.io, a high-level wallet provider that supports multisig

Just discovered https://github.com/bitpay/bitcore-node, which seems to be a more focused successor of BitPay's insight API using their "bitcore" API (http://bitcore.io/guide/). Looks pretty nice, if you're aiming at self-hosting!

Wow. It looks great. I got my node blockchain up to date so it might be a good time to try this one out. Thanks for it!

Seems like a total memory muncher, though. Always crashed on my machine due to low memory, but I was running insight in parallel 

Still wondering why anyone would do a database in nodejs...

Would love to see a list of differences for bitcore-node vs. insight, for now it seems a bit like a copy.

It's maybe worth mentioning here that BlockTrail now implements a 'Fair Use Policy' - so it's totally FREE

Any chance Blocktrail will offer these two functionalities?

1. Get tx data: given a tx hash, return its hex data (also for unconfirmed txs). (edit: sorry, I noticed this was already in the 'Get Transaction' function, as 'raw')
2. Push tx: given a tx (as hex data), push or broadcast it to the network.

I love blocktrail (my absolute #1 preferred API) but I really miss these two functions.

While I'm at it, something else that would be great as well:

3. Get tx propagation: given an unconfirmed tx hash, returns an estimate % of nodes that have this tx in their mempool.

BlockTrail has a `push tx` endpoint, the documentation is lacking a bit behind on some of the new features added;
https://api.blocktrail.com/v1/BTC/send-raw-tx?api_key
either POST a raw hex or JSON {hex: <rawhex>}

While you are here: out of curiosity, is Blocktrail based on bitcoin core (with heavy extensions on top of it, of course), based on a different client (eg, btcd) or completely custom?

BlockTrail is based on bitcoin core with heavy extensions, yes.

This is one of the reasons we were able to maintain all of our infrastructure (block explorer, API's, etc) on the correct chain, which in turn, left our users happy.

Yes, that is certainly an advantage over using a custom software directly. Thanks for replying!
