Mathpix is a tool which can covert $\TeX$ image to $\TeX$ expression, they also say they can return a string which is compatible with the Wolfram Alpha engine if possible.

I found their documentation and did such an attempt:

doc: https://docs.mathpix.com/#processing-a-single-image

img = Import@"https://raw.githubusercontent.com/Mathpix/api-examples/master/images/limit.jpg";
base64 = ExportString[ExportString[img, "JPEG"], "Base64"];
        "Method" -> "POST",
        "Headers" -> {
            "app_id" -> "trial",
            "app_key" -> "34f1a4cea0eaca8540c95908b4dc84ab",
            "Content-type" -> "application/json"
        "Body" -> {
            "src" -> "data:image/jpg;base64," <> base64,
            "format" -> <|"wolfram" -> True|>
] // URLExecute[#, "RawJSON"]&

Then Mathematica kept asking me to input Authentication Require, and no matter what I do with that, it always return:

    "error" -> "Invalid credentials",
    "error_info" -> <|
        "id" -> "http_unauthorized",
        "message" -> "Invalid credentials"

I don't know what Authentication Require is, can I avoid jumping out of that verification.

  • $\begingroup$ For github.com/oovm/Mathpix, How do you set the key in PersistentValue["Mathpix", "Local"]={"$KeyName","$KeyValue"};? Is "$KeyName" supposed to be replaced with a string representing the keyname? And what is the key name? $\endgroup$

  • $\begingroup$ It's the trial key, if you don't set your own key, this will be used by default. This key was valid before, but now it seems to have been cancelled. $\endgroup$

  • $\begingroup$ So I'm assuming the App ID and the App Key from our account on the mathpix website get pasted in inside the quotes? imgur.com/a/UKpR9EQ $\endgroup$

  • $\begingroup$ Or do we on a separate line put $KeyName = myusername123 $\endgroup$

  • $\begingroup$ Also, it seems like running this : ResourceFunction["GitHubInstall"]["GalAster", "Mathpix"] doesn't provide a Mathpix function. ? Mathpix returns Missing["UnknownSymbol", "Mathpix"] $\endgroup$

Try Mathpix API in Mathematica
