um... I wonder what other companies are using.

if D Company use C Company API, C -> B. like...
ACompany -> BCompany -> CCompany -> DCompany

If A has a problem.... b,c,d will also have problems.

I don't quite get what you're saying. Each company produces their own data, based on their service usage. They're independent of each other, so there's no dependency at all unlike what you illustrated. Sites like coinmarketcap compile different companies' data into one large list, which is what you want to do?

That being said, if you want to collect data on your own, you have to use individual exchange APIs to merge them together like what coinmarketcap does.

There are lies, damned lies and statistics. MTwain

I'm not sure what you want to create. Exchanges can provide you with an API so that you can pull information into your own system.

For example, if you want to control current value of your crypto assets on Excel, you can:

1. Create a sheet where you download current value for all cryptocurrencies.

To do this:

a) Create a Query (New Query -> From Other Souces-> From Web).
b) Provide a URL such as " https://api.coinmarketcap.com/v1/ticker/?convert=EUR&limit=0" to define the Query.
c) A Query editor will appear with a lists of rows labeled "Record". Choose the "Convert to Table" button.
d) Click on the double headed button next to Column1 to display all column names included in the record and press ok + Close and Load.

A new Tab should at his point have been created with current values from exchange API (coinmarketcap).

2. If you want to keep track of your own specific crypto values, you can now create a second Tab with your crypto name and acronimum, and use the Vlookup function to search for the current value of your crypto and multiply that by the amount you have.

3. All you have to do is refresh your data Tab everytime you want a current update on your crypto value.

P.D. The above is how it's done on excel 2016.

What pooya87 said.

If you want to collect price data of bitcoin or other cryptocurrencies for your website/project you're making or for your personal portfolio tracker for instance, you can use CoinMarketCap's API[1] for that.

exchanges aren't "collecting" data, they are producing date.
the price, volume, ... are the history of what has happened on their platform when people made trades with each other filling orders, etc.

maybe if you explain what you are planning to do with this "data" it can become clearer where and how you can obtain it.

I want to collect price, volume data. Is there a way to get bitcoin data without 'Cryptocurrency Exchange(like bitthum API, XXX API...etc.)'?
I want to know how the exchanges are collecting data. maybe it will be faster and fewer errors. maybe...
