Chuck Norris Database API
Overview
The Chuck Norris Database API (ICNDB) delivers random Chuck Norris jokes as JSON with zero setup — no API key needed, just a simple GET request. You can filter by category, request a specific joke by ID, or replace the default name with a custom one using query parameters. It's one of the easiest APIs to start with for learning HTTP requests and JSON parsing.
Beginner Tip
Use the 'firstName' and 'lastName' query parameters to personalize jokes with any name, making it fun for building custom greeting bots.
