How this service works
Open Trivia DB category ids and names, for filtering trivia questions
Output
Returns a JSON object with a boolean 'found' field, an optional count of categories, and an array of category objects each containing a numeric ID and a name string corresponding to Open Trivia DB categories (e.g. Science: Computers, Entertainment: Film, History).
Example use cases
Trivia night category picker
“Before I start pulling trivia questions, can you fetch all the available categories so I can choose which topic to use for tonight's quiz?”
Building a category dropdown for a quiz app
“I'm setting up a trivia quiz and need a full list of category names and their IDs from the Open Trivia DB so I can populate my category selector.”
Checking which science topics exist in trivia
“Can you look up all the trivia categories and tell me which ones are science-related, along with their IDs?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/trivia/categories?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover valid category IDs and names from Open Trivia DB before querying trivia questions, or when you want to present users with a list of available quiz topics. Prefer this over hardcoding category IDs since the upstream DB may add or rename categories.
Side effects
- Upstream Open Trivia DB unavailable — returns found: false or empty categories array
- Network timeout — may return an error response with no categories
- Payment failure — x402 payment not accepted, request rejected before processing
