Does pure file uploading/downloading from Wolfram Cloud consume cloud credits?

Question

If I use CopyFile to copy a large file to the wolfram cloud (say 100MB), and got say 10 downloads per day (for 1GB/day of download activity), does this consume cloud credits (or cost extra money against most Wolfram/Mathematica subscriptions)?

Answer 1

Credits are not deducted for file operations like CopyFile, FileExistsQ and fetching cloud objects like CloudGet etc.

In[137]:= $CloudCreditsAvailable

Out[137]= 5849525

In[138]:= CopyFile[$InstallationDirectory <> 
  "/Documentation/English/System/ExampleData/coneflower.jpg", 
 CloudObject[]]

Out[138]= \
CloudObject["https://www.wolframcloud.com/obj/0fb031a3-ea72-413b-9b84-\
29667ef289f0"]

In[139]:= $CloudCreditsAvailable

Out[139]= 5849525

For evaluating dynamic cloud objects like APIFunction/FormFunction, running deployed Manipulates and CloudEvaluate the user credits are deducted.

e.g. Below evaluations will deduct credits.

CloudDeploy[Manipulate[a, {a, 1, 20}]] (* Using interactions in deployed objects. *)

In[129]:= api = 
 CloudDeploy[APIFunction[{"c" -> "Integer"}, #c! &], "factAPI"];

In[128]:= $CloudCreditsAvailable

Out[128]= 5849527

(* Evaluating APIFunction/FormFunction *)
In[130]:= URLExecute[api, {"c" -> 59}]

Out[130]= \
"138683118545689835737939019720389406345902876772687432540821294940160\
000000000000"

In[133]:= $CloudCreditsAvailable

Out[133]= 5849526

(* Using CloudEvaluate *)
In[134]:= CloudEvaluate[159!];

In[137]:= $CloudCreditsAvailable

Out[137]= 5849525

We are working on documenting cloud-specific functions extensively. I think its good to specify which functions will deduct credits. I will discuss with my team about it. Thanks
