WolframAlpha
WolframAlpha exposes its computational-knowledge engine through seven purpose-built APIs — Full Results, an LLM API returning JSON tuned for language models, Simple, Short Answers, Spoken Results, and more — covering step-by-step math, unit conversion, and factual Q&A. Access is keyed via an `appid` query parameter with a free tier of 2,000 non-commercial calls per month, above which usage requires a paid production plan. Results come back as XML with plaintext/image pods, spoken-word text, or LLM-oriented JSON depending on which endpoint you call.
