Power a calculator with the Wolfram LLM API

Dev, web & IT · Business data & reporting · checked 2026-10-17

Have Codex build a small calculator page that sends questions to the Wolfram|Alpha LLM API (an AppID is required) and shows the computed answer with its inputs.

Goal

Ship a calculator that gets the math right because it doesn’t rely on a chat model.

Confirmed means the vendor documents it (linked). It doesn't mean IonBin has tested it. AI-platform and human steps need no source.

Human approval

You test and approve before anything is public.

Keep the human approval step: You test and approve before anything is public.

Starter prompt

Goal: Ship a calculator that gets the math right because it doesn’t rely on a chat model. Tools involved: Codex, Wolfram. Your part: writes the calculator and the api call. Work step by step, show me each draft or proposed change, and wait for my approval before anything is sent, published, signed, filed or changed in a live system.

Which AI platforms can run it

PlatformStatusWhy
Claude (incl. Claude Code) Confirmed Every MCP and API step is documented for this platform.
OpenAI Codex Confirmed Every MCP and API step is documented for this platform.
Google Antigravity Confirmed Every MCP and API step is documented for this platform.
ChatGPT Confirmed Every MCP and API step is documented for this platform.
Gemini To verify Wolfram: code execution to verify (or run it in Make or n8n)
Perplexity To verify Wolfram: code execution to verify (or run it in Make or n8n)

Computed from the MCP and API steps only: "Confirmed" needs the tool's docs to name the platform and the platform to support the connection. Browser, upload and human steps work from any platform.

What we checked

  • LLM API. Queries go to https://www.wolframalpha.com/api/v1/llm-api with two parameters: your AppID and the URL-encoded input. You get an AppID from the Wolfram|Alpha Developer Portal (My Apps), and each application needs its own. Responses are plain text built for language models, capped at 6,800 characters by default; the maxchars parameter changes that.
  • Limits and terms. The documentation doesn’t list per-AppID usage limits. Use of the LLM API is subject to Wolfram’s API Terms of Use and Commercial Terms of Use. Check those, and contact Wolfram, before putting a calculator in front of the public.
  • Keep the AppID server-side. Have Codex call the API from a small server function rather than from browser code, so visitors can’t copy your AppID (our advice).

Set it up

  1. Ask Codex for a page with an input box and a server function that calls the LLM API and returns the text.
  2. Show the computed answer with Wolfram’s input interpretation, so users can see what was calculated.
  3. Test edge cases: ambiguous inputs, units, very large numbers and empty input.
  4. Approve it before you publish.
