OOPs, bad news. Blockchain.info blocks transactions with an OP_Return as 'non standard transactions' - https://blockchain.info/rejected . Is there a better API to push transactions into?
Standard node doesn't relay non-standard tx. So it never reaches mining pool. So you need to push into directly to pull, as TheButterZone sad before eligius pool allows it.
Topic: How to convey transaction to network (Read 1981 times)
It should work with any language that can do HTTP POST including very low level programming languages. I think .NET is ops preferred language.
Yep. Exactly. But could somebody post an example of an HTTP POST in .Net that sends a transaction into a node (the network) - (which node?) (a permanent known node?).
Please post some code which does this if you can.
Sorry, I don't know anything about .NET, but almost every language I've worked with has some sort of system("systemcommandhere") call. Why not just use .NET's version of system() and then the classic curl binary:
$ curl -X POST --data "foo=bar&baz=quux" URL
HTTP post with command line is probably the easiest method. He could use a wrapper for a HTTP client request or execute a system call. I don't think Windows comes with a copy of curl but there are windows ports of curl.
He can use something like this:
Code:
ProcessStartInfo transaction = new ProcessStartInfo ("curl.exe .....", "parameters");
Process.Start (transaction);
Easiest way? You've answered yourself, yes, Blockchain can do that https://blockchain.info/pushtx
You can also just use Electrum... or Armory if you have it. You can also push it here https://btc.blockr.io/tx/push. Also here https://brainwallet.org/#tx

Yeah, I don't know how to write the WebRequest object in .Net to send to the push URL at blockr. Having trouble with the encoding and stuff. Blockchain.info has a sweet API for .Net - but then they go and block OP_Return. Why do they block OP_Return? That is totally stupid. Does any other blockchain API providers have a nice .Net code on GitHub?
Holy shit this is hard.
I don't understand what .NET has to do with it. If you're using that blockchain API, can't you just use HTTP POST. Programming language shouldn't matter should it?

Need to remove all spaces and carriage returns from that hex so that it is an unbroken string of characters, then it's valid. I just broadcasted it via Electrum.

Hmm, that's seems cool.
However, I can't get this one to publish. Any idea what's up?

I have a most perfectly formed transaction ready to go.
Maybe not! 
Someone wrote a blog entry which covers this - scroll down a little and there's a python script to do it.

I have a most perfectly formed transaction ready to go. What is the easiest way to transmit it into the bitcoin network for processing?
I don't want to set up and run bitcoind on a local machine. Too much agro. Is there a trusted node with a permanent IP which I can send (via some protocol) the bytes to? What is the minimum handshaking that must be done to establish a connection to this node with a know IP. Is there an easier way? Does blockchain.info support that?

You can use a thin client library for that, have a look at pybitcoinlib. Transactions can be pushed using blockchain.info or an exchange.
I poked around a bit in that library, I see where in an example "import socket" is used to send to a local IP. I guess socket uses TCP for the connection. However, like the OP, I'd also be interested in knowing if it's possible to connect in this way to any particular full node.

Substitute the tx hex for your own, and this is good to go. I haven't used it over the CLI before, it will reject transactions sometimes, so watch out for that. It sometimes states there is a problem with the transaction, but it gets broadcast anyway.
