The code to be evaluated is passed to the API using the "code" parameter:

curl -X POST https://services.wolfram.com/api/apis/v1/WolframLanguageCompute \ -H "Content-Type: application/json" \ -H "Authorization: YOUR-API-KEY" \ -d '{ "code": "TrigExpand@Sin[2x]" }'

Images and graphics are returned via a Markdown image URL:

curl -X POST https://services.wolfram.com/api/apis/v1/WolframLanguageCompute \ -H "Content-Type: application/json" \ -H "Authorization: YOUR-API-KEY" \ -d '{ "code": "Graphics[{Red, Circle[]}]" }'

The free-form prompt character, =, can be used to represent ctrl-= in inputs to retrieve curated data through natural language:

curl -X POST https://services.wolfram.com/api/apis/v1/WolframLanguageCompute \ -H "Content-Type: application/json" \ -H "Authorization: YOUR-API-KEY" \ -d '{ "code" = "\[FreeformPrompt]["France population"]" }'

	"success":true,
	"uuid":"8f4cbebd-d08d-4c2d-9745-583e22668ebf"
}"

The integer appearing in the output label can be overridden with the "line" parameter:

curl -X POST https://services.wolfram.com/api/apis/v1/WolframLanguageCompute \ -H "Content-Type: application/json" \ -H "Authorization: YOUR-API-KEY" \ -d '{ "code": "Integrate[x, {x, 0, 1}]", "line": "50" }'

The size of the output can be limited using the "maxChars" parameter:

curl -X POST https://services.wolfram.com/api/apis/v1/WolframLanguageCompute \ -H "Content-Type: application/json" \ -H "Authorization: YOUR-API-KEY" \ -d '{ "code": "ExampleData[{\"Text\", \"AliceInWonderland\"}]", "maxChars": 1000 }'

Elision markers << and >> indicate where the output was shortened and by how much:

she told her sister, as well

Evaluation time can be limited using the "timeConstraint" parameter:

curl -X POST https://services.wolfram.com/api/apis/v1/WolframLanguageCompute \ -H "Content-Type: application/json" \ -H "Authorization: YOUR-API-KEY" \ -d '{ "code": "Pause[60]", "timeConstraint": "10" }'

When the time constraint is exceeded, "result" is a Failure expression:

{
	"result":"
Failure["EvaluationTimeExceeded", 
 <|"MessageTemplate" -> "Evaluation exceeded the `1` second time limit.", 
  "MessageParameters" -> {10}|>]",
	"code":200,
	"success":true,
	"uuid":"a83f98f1-6a88-4e16-860a-833d8369bd48"
}

The returned JSON contains the following fields:

• result (string) The result of evaluating the Wolfram Language expression passed in via the "code" body parameter
• code (integer) API status code (e.g. 200, 400, 403, 501, ...)
• success (Boolean) true or false depending on whether the request completed successfully
• uuid (string) A unique ID labeling the response

This status indicates a success.

This status indicates that the API did not find an input parameter while parsing. In most cases, this can be fixed by checking that you have used the correct syntax for including the input parameter.

This status is returned when a request contains a missing or invalid API key in the authorization header. Double-check that your AppID is typed correctly and is using the correct syntax.

This status is returned if a given input value cannot be interpreted by this API. This is commonly caused by input that is misspelled, poorly formatted or otherwise unintelligible. Because this API is designed to return results for use in LLMs, the body of the 501 message may contain suggested inputs. You may occasionally receive this status when requesting information on topics that are restricted or not covered.
