Overview

Jservice gives you free access to a massive database of Jeopardy! clues and categories with no API key required. You can fetch random clues, search by category, or grab the final Jeopardy question — perfect for building quiz apps or trivia games. Just send a GET request to get started instantly.

Beginner Tip

Start with the /random endpoint to fetch a single clue — the response includes the question, answer, category, and point value. No authentication needed, so you can test directly in your browser.

Available Data

The kind of data this API exposes, based on its documentation. We could not call the endpoint to confirm the exact field names.

Use case: Integrate jeopardy question database data into web and mobile applications

Example Response

Illustrative shape only — we were not able to call this endpoint (it requires credentials or exposes no public sample URL), so the fields below show the kind of data this API returns rather than a recorded response.

Common Errors & Troubleshooting

Generated guidance based on this API's documentation, not observed by us. Treat it as a starting point and check against the provider's own error reference.

404 Not Found Requesting a category or clue ID that does not exist in the database

✓ Use /api/categories?count=100 to discover valid category IDs before querying specific ones

Empty or null answer field Some Jeopardy clues have redacted or missing answers in the source data

✓ Check if the answer field is null or empty before displaying it, and skip or flag those clues in your app

Slow response times The free public API may have occasional latency spikes

✓ Add a reasonable timeout (5–10 seconds) in your fetch call and display a loading state in the UI

Metadata Score Breakdown

Estimated from metadata — endpoint not independently tested

This score is estimated from observable metadata — HTTPS support, authentication model, declared CORS, and documentation reachability — because the API requires authentication or exposes no publicly testable endpoint. The five-signal breakdown is only shown for live-tested APIs.
