Most people could agree that observing a picture, a simple graph, or a pie chart is easier and more efficient than scrolling through blocks of text or trying to parse out useful insights from looking at numerous columns in a spreadsheet. This common knowledge is the basis of why visualization is so important. Also, in a rapidly changing world, people seek ways of becoming more efficient, ways of increasing the time spent focusing on the insights, rather than pouring endless hours and effort into collecting the necessary assets to gain those end results that determine so much. This is why automatization nowadays is a key topic. Now, we are happy to introduce our newest feature that combines the two - automatization and visualization. The Google Append feature is a data export feature that, when enabled, transfers all the data of your Web Scraper Cloud jobs to a specific folder and individual Google Sheets in your Google Drive account.

CoinMarketCap Crypto Scraper
You can experiment with endpoints and query strings as described in the documentation to see other types of cryptocurrency data, but if you just want to jump in and get a feel for it, play around with the URLs you enter in the API URL path field.
Here is the template link. When I load the data into google sheets it only loads coins. Good question! Thakns so muc! I successfully did it. However, there are many critical coins that are not being reported. Which URL are you using? Can you provide more details on how to use the importapi in this context? Hey Cris, please check this article. When I run the request the timestamp shown is T Could you help to fix this issue?
Are all of them looking off? But I have some formulas put in the Page 1 limit and these formuals are lost when I select Overwrite.
Hi Ragu, append mode should return all data except the headers from the first row, to avoid repeating headers within the sheet. Are you seeing something different?
That looks fine to me, I think you just need to remove the quotation marks, e. Also it should be? My last question is how to get the logo of each one of these cryptos. Should I need to create a new endpoint and run it from another spreadsheet or can I run it in the same one? Also, if you want to actually see the images in your sheet, you can add a cell containing the IMAGE function, e. Hi Ana and thanks a lot for your article! Btw, I recommend using compact report style under Output Options to make the output easier to read.
Thanks, it works fine but how can i filter columns? Hi there, you can try this: data. Alternatively, you can just query the columns you want into a new sheet using Sheets functions. Thank you.
I want to create a spreadsheet where i have the overview on my coins and their current values. Therefore i need to build connections from the prices of the coins to other fields. What about if the rank of the coins change, will the connection be wrong or invalid afterwards? What is the best way to connect the fields? Hey Florian! If I understand correctly, you have a list of coins in one sheet, and want to keep all the data lined up? If so, you can just use Google Sheets functions for this, for example put all your coins in one column and then use VLOOKUP to pull associated data into associated columns.
My data does not update. What do i have to configure for automatic updates? Automatic updates are handled by scheduling. Hello Ana, thank you for the wonderful detailed article! I was able to set this up in my spreadsheet in no time at all. Right now all price quotes are in USD. Thank you very much! Can you please try that and see how it goes?
I want to add convert for the usd prices that i receive from coinmarketcap via that method. Then i want a real time converter to change the prices to euro as well.
Sheets itself also has currency conversion functions, e. So i have one sheet in which all the data for the top coins come and another one in which i have my portfolio.
Here is the problem though. The coin ranking is constantly change so basically except the top 2 coins all the other prices change as well and i have to manually change it each time. However, when I request that token, I get a quote for Global Rental Token which apparently has the same symbol. Is there a way to specify exactly which token I desire? I see, in that case I think you need to use the slug instead of the symbol.
Which makes it impossible to do anything further with this data and link to other sheets etc. If the problem is with rows shifting, then you can choose from many different Sheets functions to handle this. Hi All, how do I get this to change prices in real time. Neither method is exactly realtime though scheduling is limited to 1x an hour, and importapi to once every couple minutes.
Hello, first of all, congratulations on your website. Hi, Great work! Can you please tell me why it does not recognize and fetch data for all these coins? I have put all these into Inputs tab. Please change it to AMLT and your request should work. Hello, I built a spreadsheet to keep track of my investment vs return for crypto.
Hey Nicolas, sure, you can put all your symbols into one cell e. Hi, I tried you URL as above and the result is displayed horizontally. Only pulls the first hundred. Hi there, by default CoinMarketCap limits data to rows. If you still need more records after that, you can apply pagination handling. So maybe you can check or post in there for more info. Is it possible to just pull a list of specific coins? Does that make sense? But it sounds like your table is linking to specific cells, right?
With VLOOKUP you set the name of the coin as your lookup value, then set your sheets to read from that, rather than having them look for a fixed cell location. Hope that helps point you in the right direction! Hello Ana, Congratulations on your work. Hey Sergio, what does the error message say? Thanks Ana for your quick response.
Error: Web. It should do the vlookup, but somehow it is not successful. I tried it with the template sheet out of the box. Anyone else got this problem? Hey Phil, thanks for the message! To fix, go to the Summary tab cell B9. Then copy it all the way across the row and the data should populate correctly. Hey Ana, yep, this was exactly what caused the problem! Thank you so much for your quick and helpful response!
All the best for you and your assets! So I think you have the following options:. Awesome tutorial. Can you please tell me how should I use this tutorial to see all the recently listed coins on CMC? First of all, thank you very much for the tutorial as it has helped me to understand the CoinmarketCap API. I was writing to you in case you can guide me to capture the different markets for one or more currencies. Do you mean you want to get the price of Bitcoin on different exchanges?
Yes, i would like to try with arbitrage. I almost get using Excel but the perfomance is horrible when i try to get the top coins with their respective pairs. Cool, good luck! Hi Ana. It has stopped working however about 2 weeks or so ago. Do you know if the endpoints has been changed? Hey Van! Can you please confirm that this is the URL producing the error?

Fan Published Since it is difficult to protect servers from high-volume scraping, a new way to reduce excessive requests is needed. Using rougher methods such as rate limit or IP control mechanisms are not sufficient. In this report we propose a new solution to counter high-volume web scraping with blockchain technology. We create a cryptographic algorithm and use it on a mobile device to communicate with an Ethereum network with the purpose to control server access. Our studies seem to indicate that… Expand.
A Blockchain-Based Solution to High-Volume Web Scraping With Smart Contracts on Ethereum
Web scraping mostly involves text-intensive tasks such as product review scraping, gathering real-estate listings, or even tracking online reputation and presence. When one application scrapes only String data types for qualitative analysis, it may not need type safety. However, in case the end goal of the web scraping is to do quantitative analysis with prices or weather forecasts, using a type-safe language might be quite handy. In this article, we aim to give a small and interesting example of price scraping for crypto-currencies by using Scala and storing those into a PostgreSQL database. To scrape the prices we selected to use CoinMarketCap homepage. It is a crypto-currency knowledge website, which gives information also on market capitalizations relative market sizes , circulating supply, and trading volumes.
