How can I import "curl" API in MATLAB using webread function?

I am trying to import a dataset from a website (https://www.sapsailing.com/sailingserver/webservices/api/v1/) using their API. The specific website to use (from their example) is: curl "https://www.sapsailing.com/sailingserver/api/v1/regattas/Kornati%20Cup%202019%20-%20B46/races/B46%20R1/startanalysis"

In the case above, I believe my issue is the "curl" portion of the website. I am unsure what this is or how to code it into MATLAB. I tried the following:

api_url = 'https://www.sapsailing.com/sailingserver/api/v1/regattas/Kornati%20Cup%202019%20-%20B46/races/B46%20R1/startanalysis';

api = webread(api_url);

With this error message:

Error using matlab.internal.webservices.HTTPConnector/copyContentToByteArray

The server returned the status 404 with message "Not Found" in response to the request to URL

https://www.sapsailing.com/sailingserver/api/v1/regattas/Kornati%20Cup%202019%20-%20B46/races/B46%20R1/startanalysis.

Error in readContentFromWebService (line 46)

byteArray = copyContentToByteArray(connection);

Error in webread (line 125)

[varargout{1:nargout}] = readContentFromWebService(connection, options);

I also included "curl" in the webread function, but that did not work either.

I am able to import data from a similar website using this code:

api_url = 'http://www.sapsailing.com/sailingserver/api/v1/leaderboards';

api = webread(api_url);

I appreciate any help.

Thank you,

Josh

What about using curl instead? This is included in Linux, MacOS and Windows also:

system(['curl "https://www.sapsailing.com/sailingserver/api/v1/regattas/', ...
    'Kornati%20Cup%202019%20-%20B46/races/B46%20R1/startanalysis"'])

The web service replies: "Could not find a regatta with name 'Kornati Cup 2019 - B46'"

So there seems to be another problem.

Thank you, this definitely helps.

I tried another race using this code:

system(['curl "https://www.sapsailing.com/sailingserver/api/v1/regattas/', ...

'Hempel%20World%20Cup%20Series%202022%20-%20Round%201%20ILCA%206/races/ILCA%206%20GOLD%20-%20Race%2010/maneuvers"']);

It looked like it worked, however I got this message:

Output truncated. Text exceeds maximum line length for Command Window display.

Do you have any tips on how I can save these data in a table within the MATLAB workspace or export them as a csv? This is the first time I've used the "system" command. Thank you for teaching me that!

Try:

system('curl "insert your URL">D:\YourFolder\FileName')

to write the output to a file instead of displaying it in the command window.

That worked geat. Thank you!
