Try it against the live API

Pick some filters and the request changes to match. Each one goes to the real API, with no key, and brings back a fresh question.

You can also filter by tags and region, and ask for up to 50 questions at a time without a key. Filtering guide. In TypeScript, @trivia-api/sdk has a typed function for every endpoint and no dependencies. See the quickstart.

Image and typed-answer questions, translations and sessions need an API key. See plans

Five things you won't have to build yourself

Random questions get a game started. These are what it needs next, each one a parameter or an endpoint away.

Let players type their answers

Text input questions have no options to pick from. Send what the player typed to the validate endpoint and an LLM decides whether it's right, so typos and other wordings still count.

There's no list of accepted spellings to maintain, and answers can be checked in any of the translated languages too.

Which planet has the most moons?

“Saturn”Accepted: Exact match
“the planet saturn”Accepted: Same answer, different wording
“Satrun”Accepted: A typo

// response for “Satrun”
{ "isCorrect": true, "correctAnswer": "Saturn" }

Ask with pictures

The four options are photos: people, places, flags, maps and food. Every image arrives ready to lay out, at several sizes, with the author and source you need to credit it.

type=image_choice

Available with Complete subscription

Option A: Grand Central terminal in New York, NY — Each image comes in up to 7 sizes, credited to its author. Here: Fcb981; Eric Baetscher, Tonchino, Yakult6067, Diliff.

Option B: South facade of the Basilique du Sacré-Cœur de Montmartre — Each image comes in up to 7 sizes, credited to its author. Here: Fcb981; Eric Baetscher, Tonchino, Yakult6067, Diliff.

Ask in 9 languages

Add a language code to a request and the question comes back in Spanish, Dutch or Hindi, with its answers translated to match. The same question id works in every language, so players can share a round across them.

Never ask the same question twice

Create a session for each player or game and pass its id when you ask for questions. The API remembers what it has sent and skips it next time, and tells you how many are left.

Find questions by what they're about

Search by meaning rather than keywords, so asking for creatures from ancient myths finds Medusa and Pegasus. Use it to let players pick a topic, or add query to a questions request for a random round on one.
