Comparison
WebKnox vs Wolfram|Alpha API
Wolfram|Alpha is a computation engine. WebKnox is an answer API with ready-made cards. They overlap less than you might think, and some apps should use both.
The short answer
Choose Wolfram|Alpha for computation
Maths, science, engineering and curated data. That's what it was built for, and WebKnox doesn't try to match it.
Choose WebKnox for cards
Weather, recipes, nutrition, comparisons, translations and media, as cards your users can see and tap.
Side by side
| Topic | Wolfram|Alpha API | WebKnox |
|---|---|---|
| What you get | Text, images or result pods, from eight APIs | A typed card, plain text, speech text and sources, from one endpoint |
| Strongest at | Computation, maths and curated data | Everyday questions in chat, voice and displays |
| Ready-made UI | None; the closest are images and XHTML summary boxes | A web component with 17 card types and themes, plus hosted embeds and images |
| Free use | Up to 2,000 calls a month, non-commercial | 50 tokens a day, in any project, with a small credit |
| Commercial price | Not published; you contact sales | Public plans from $9 a month |
| Credit and terms | Commercial use requires “Computed by Wolfram|Alpha” with a link; no caching without a written agreement | A small credit on Free, none on paid plans |
| In AI apps | The Wolfram Foundation Tool offers MCP; no public price | A remote MCP server with 10 free answers with a card a day |

What the swap looks like
Both are one HTTP call. Wolfram's LLM API returns text for a model to read. WebKnox returns a card for your user to see.
curl "https://www.wolframalpha.com/api/v1/llm-api?input=weather+in+Dresden&appid=$APPID"
curl https://api.webknox.com/v2/answers \
-H "Authorization: Bearer $WEBKNOX_API_KEY" \
-H "Content-Type: application/json" \
-d '{"messages": [{"role": "user", "content": "Weather in Dresden"}]}'
Using both
Give your model both as tools: WebKnox for questions with a card, Wolfram|Alpha for computation. WebKnox answers matched: false when it has nothing, so the model can move on.
Questions about the comparison
Is WebKnox a Wolfram|Alpha alternative?
For everyday questions shown as cards, yes. For computation beyond conversions and simple maths, no: Wolfram|Alpha is the better tool there.
How much does the Wolfram|Alpha API cost?
Non-commercial use is free for up to 2,000 calls a month. Wolfram doesn't publish commercial prices: its pricing page leads to a contact form. Older price lists still turn up in search, so ask Wolfram for a current quote.
Does WebKnox do maths?
Conversions and simple maths, in English and German. For anything harder, use Wolfram|Alpha.
Can I use the free plans in a commercial product?
WebKnox's free plan works in any project, as long as its credit stays visible. Wolfram|Alpha's free tier is for non-commercial use.
