About

JSONing turns any JSON object into an instant mock API endpoint right in the browser: paste JSON, get a URL, start calling it. No signup, no key, zero friction. Endpoints are deleted once a day, which is perfect for throwaway prototyping and agent testing. When your agent needs a fake backend to practice against, this is the fastest path.

Details

No key needed. You can call it right away.
