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.

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. curl -X POST -d tx=010000000158891e8f28100642464417f53845c3953a43e31b35d061bdbf6ca3a64fffabb8000000008c493046022100a9d501a6f59c45a24e65e5030903cfd80ba33910f24d6a505961d64fa5042b4f02210089fa7cc00ab2b5fc15499fa259a057e6d0911d4e849f1720cc6bc58e941fe7e20141041a2756dd506e45a1142c7f7f03ae9d3d9954f8543f4c3ca56f025df66f1afcba6086cec8d4135cbb5f5f1d731f25ba0884fc06945c9bbf69b9b543ca91866e79ffffffff01204e0000000000001976a914d04b020dab70a7dd7055db3bbc70d27c1b25a99c88ac00000000 https://blockchain.info/pushtxOtherwise, you might be able to do something similar for this form: https://insight.bitpay.com/tx/sendThere are probably several of these insight servers around, some googling might help you have some redundancy for broadcasting.

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. @OP, the blockchain tool to accept a raw transaction over HTTP is here: https://blockchain.info/pushtx

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.

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.

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.

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.

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: ProcessStartInfo transaction = new ProcessStartInfo ("curl.exe .....", "parameters"); Process.Start (transaction);

Here https://github.com/bitcoin/bitcoin/blob/f0043c2d6d2ceddd631a76b424dd8c163f3dad66/src/main.cpp#L885 bitcoin-core prohibits to accept to memory(and eventually to relay) non-standart txs unless it explicitly setted in params. I dont know are txs with OP_Return non-standart now, but if so they will not be relayed by bitcoin-core standart wallet.
