FAQ
How long does a mock API URL last?
Mock endpoints use a time-limited URL suitable for demos and tests. Create a new mock when yours expires.
Can I use this for production?
Mocks are for development and QA, not as a permanent backend for production traffic.
What data do you store?
Only what is required to host the mock is retained for the lifetime of the endpoint; avoid sending secrets.
Is it free?
Yes. JsonOnlineParse mock APIs are free to spin up for testing.
