Most exchanges offer API solutions for market data. Here are some examples:
CryptoCompare has an API that aggregates data from many exchanges, and they also offer many query parameters. Link: CryptoCompareAPI
Additionally, many block explorers provide APIs for blockchain account information.

You have two options here:
Check out one of the data providers online. Quandl offers (mostly) free historical data for a variety of pairs and exchanges. Alternatively, if you have bucks to spare, Coinigy offers high-quality data sets on a per-month pricing model.
Roll your own data crawler, using a programming language of your choice and the ...
You can get complete and up-to-date price history here:
You can also get subsets of the data.
For details see: http://bitcoincharts.com/about/markets-api/
All of the transaction history is communicated between peers over a binary gossip protocol. You can request specific blocks, sequences of blocks, or specific transactions, and clients will normally communicate by broadcasting all of the information they receive to other peers they are connected to - enabling each client to stay mostly up-to-date once they've ...

I believe the best option for you would be to write a script which grabs the data from Kraken's API, and parses that into a CSV output that you want.
Using the API to download trade history is explained here:
http://www.CryptoDataDownload.com is new - mainly aggregates data from 28+ exchanges and lets you download it in CSV format for free. there are over 500+ pairs and the timeframes are Daily, Hourly, or Minute. No registration required or gimmicks. Data sets updated daily
It sounds like you are asking how to build a block explorer. Basically you would activate the full transaction index by adding txindex=1 to your bitcoin.conf. Parse all the history data and dump it into a database. Then keep track of all the new transaction data on your own database as blocks come in with blocknotify or real-time with ZMQ notifications.
Indeed they don't specify what it means, but the only sane option is that market/limit tag comes from the type of order that closed the deal.
For example there are two lowest sell(ask) orders hanging in the order book:
0.05 BTC at 2000 EUR
0.03 BTC at 2300 EUR
I come to Kraken and place a Market order, buy(bid) for 0.07 BTC, thus the first trade will be ...
TL;DR: It was not its creator who did that. Bitcoin's economic significance was gained similarly to any other money; but here, it started with pizza...
Let me answer by refuting the most persistently recurring false argument:
Crypto money has an intrinsic value created by clever design to provide utility in the form of safe/free/practical/... (i.e. "...
You might want to try http://www.cryptodatasets.com/ It has free raw(every trade by trade) data and sampled data from Bitfinex and HitBtc (non from MtGox since its not operating anymore).
P.S. it's my website
FirstRateData has prices and volumes, aggregated across 10 exchanges back to 2013 for Bitcoin and back to 2017 for 50 other crypto tickers.
For more complete coverage, Kaiko has data for over 500 crypto tickers - although it can be expensive...
You didn't state what format you are looking for. Investing.com has a decent tool for this. I've used it for calculating long term gains/losses.
Your updated question asked for JSON.
I would use blockchain.info
I don't think the issue is that they don't have the data. I think they're just showing the data at a lower sampling rate.
This chart draws data from three locations:
Updates once per minute, but only has 24 hours of data.
You can download the historical data of coinmarketcap.com with my developed crawler: https://github.com/roNn23/coinmarketcap-historical-data-crawler. But it's only getting the snapshots of coinmarketcap.com, maybe it's to wide for your needs.
I have posted an answer regarding the code in the stackoverflow question, but if you just want the raw (or sample) data for either BTC/ETH/LTC from Bitfinex or HitBtc, you can head over to my website at www.cryptodatasets.com.
All the data is free, and gets updated every day.
This project: https://github.com/sr-gi/bitcoin_tools might be what you're looking for...The repo has resources to dump the leveldb database into a JSON like format for review and analysis. They also created a paper discussing the format of UTXO here.
