Wolfram|Alpha

A computational knowledge engine that answers math, science, unit and fact questions by computing them, with a family of APIs including one tuned for LLMs.

It computes answers instead of searching for them, so you get step-by-step math and live figures from curated data.

For your agent

A request your code or agent can make (add your key):

https://www.wolframalpha.com/api/v1/llm-api?input=10+densest+elemental+metals&appid=YOUR_APPID

Get a free AppID in the developer portal (2,000 non-commercial calls/month); use the LLM API for compact text answers; commercial use needs a paid license; no caching of results; official MCP via WolframResearch/AgentTools or Wolfram Cloud MCP.
Attribute Wolfram|Alpha and link to the corresponding results page wherever results are shown
Do not cache results unless you have a written agreement
Free AppID is for non-commercial use only (2,000 calls/month); commercial apps need a paid license

· MCP: https://github.com/WolframResearch/AgentTools (local MCP server, needs a Wolfram Engine or Docker image); also Wolfram Cloud MCP, free for limited personal use: https://www.wolfram.com/artificial-intelligence/mcp/cloud/

Paste into your agent: Read https://agentgid.com/resources/wolfram-alpha/agent.md before using Wolfram|Alpha.

What you can build

A homework helper that sends math questions to the LLM API and links to the full result page
A unit and constants lookup tool for engineers, with Wolfram|Alpha attribution
A chatbot tool call that hands calculations to Wolfram|Alpha instead of the model
