Worked examples
A blockchain
GET /api/v1/live/wikipedia-summary?title=Base%20(blockchain)
Result: This is a list of blockchains - decentralized, cryptographic databases - and other distributed ledgers.
Fuzzy topic
GET /api/v1/live/wikipedia-summary?title=quantum%20computing
Result: A quantum computer is a computer that represents and processes information using quantum states. Quantum computations exploit phenomena such as superposition, interference, and entanglement. Quantum computers have the potential to complete some calculations exponentially faster than classical computers. For example, a large-scale quantum computer could break widely used encryption schemes and aid physicists in performing physical simulations. However, current hardware implementations of quantum computation are largely experimental and suitable for only certain specialized tasks.
A person
GET /api/v1/live/wikipedia-summary?title=Marie%20Curie
Result: Maria Salomea Skłodowska Curie, better known as Marie Curie, was a Polish and naturalised-French physicist and chemist. She shared the 1903 Nobel Prize in Physics with her husband, Pierre Curie, "for their joint researches on the radioactivity phenomena discovered by Professor Henri Becquerel". She won the 1911 Nobel Prize in Chemistry "[for] the discovery of the elements radium and polonium, by the isolation of radium and the study of the nature and compounds of this remarkable element".

About this tool
The Wikipedia REST summary for any article: the lead paragraph a human sees first, plus the short description, canonical URL and Wikidata QID. Ideal grounding for entity claims — the extract is verbatim from the article, fetched live and cached per title for a day.
Frequently asked questions
What if my title isn't exact?
Near-misses are resolved through Wikipedia's search (and reported as 'Title resolved'), so "quantum computing" lands on Quantum mechanics' summary only when that's genuinely the best match.
Is the summary the whole article?
No — it's the lead extract only. For deep questions, fetch the full page with the url-reader tool using the returned page URL.
