https://estimatefee.com

API
You can use https://estimatefee.com/n/$CONFS where $CONFS can anything from 2 to 1008. We directly proxy the results from bitcoin core using `estimatesmartfee` (with a 30 second cache), so the value is in bitcoin per 1000 bytes. If you're using this, make sure to put a fallback. If it works, it'll be accurate. But don't expect five 9s of reliability -- because, really, I really only made the API to look cool.

Ken Shirriff's blog:

1. Bitcoins the hard way: Using the raw Bitcoin protocol

"All the recent media attention on Bitcoin inspired me to learn how Bitcoin
really works, right down to the bytes flowing through the network. Normal
people use software that hides what is really going on, but I wanted to
get a hands-on understanding of the Bitcoin protocol."

2. Bitcoin mining the hard way: the algorithms, protocols, and bytes

"This article explains Bitcoin mining in details, right down to the hex data and
network traffic. If you've ever wondered what really happens in Bitcoin mining,
you've come to the right place."

"Unofficial Documentation of Robinhood Trade's Private API

Robinhood is a commission-free, online securities brokerage. As you would
expect, being an online service means everything is handled through a request
that is made to a specific URL.

Before I go too far, I must say that this is a big, messy work in progress. I'll
continue to update this as I figure more out. Sections marked TODO are in my
head but I haven't found the time to describe them yet. Work in progress and
all.

Oh, and I do not work with or for Robinhood Financial, LLC."

Looking for an all in one API to read balances from exchanges (self.cryptodev)

Is there an API that supports lot of exchanges that will allow me to provide it keys and it will give me coin balances.
I am only interested in reading the data from exchanges and never writing.
I know each exchange has their own api and they require the user the to setup keys which is fine but instead of having to develop for each exchange I am hoping there is an API that i give it the exchange, the private key and it will give me balances/read-only data.

Here's a quick overview (text copied from the repositories):

eWallet Backend: The eWallet allows developers to run a (local) ledger through a web interface. The eWallet will later be plugged to a blockchain and connected to a decentralized exchange. All the eWallets will then become a federated network forming the top layer of the OMG network, allowing the exchange of any currency into any other in a transparent way. Also check out the sample eWallet server which demonstrates the eWallet.


iOS SDK: Allows iOS developers to integrate iOS apps with the eWallet Server. Also check out the sample iOS application which demonstrates the SDK.
