Terms of Service

Last updated 12 September 2026

Using Fake API means accepting what is written here. If any of it does not work for you, the answer is to not use the service.

What the service is

Fake API lets you define mock REST endpoints in the browser and call them over HTTPS. It is a development and testing aid. It is not a backend, not a database, and not somewhere to run anything a real user depends on.

No charge, and no guarantee

The service is free and is provided as is, with no warranty of any kind. There is no uptime commitment. It can be slow, it can be down, and it can change or stop entirely without notice. Do not build anything on it that would hurt to lose, and do not make it a dependency of a production system or of a test suite you need to be green tomorrow.

Your endpoints are public

Anyone holding an endpoint's URL can call it, and for a trial endpoint can change it too. There is no access control on a mock, because a mock a client cannot reach is not worth having. So keep real personal data, credentials, API keys and anything confidential out of every response body, header and prompt. What you put in a mock, you have published.

Limits

A free account includes 5 projects, 10 endpoint groups per project, 10 endpoints per group, and 30 AI generated designs per day. A response body is capped at 30,000 characters and an artificial delay at 60,000 ms.

The trial box on the home page needs no account and allows 5 endpoints. Those are swept after 24 hours and do not transfer to an account you create later.

Rate limits apply to the service as a whole and to trial sandboxes per address. All of these figures can change as the service is tuned.

What you may not do

Do not use the service to host or serve malware, phishing pages, or anything illegal where you are. Do not use a mock endpoint to impersonate another service or organisation in a way meant to deceive. Do not store other people's personal data in it. Do not attempt to break, overload or work around the limits, whether by scripting account creation, scraping, or otherwise. Do not resell access to it.

Suspension

An account or an endpoint that breaks the section above can be removed without warning, along with everything under it. Where there is a judgement call to make, we will make it.

Your content

What you create stays yours. You grant only what is needed to store it and serve it back over HTTP, which is what the service does. Deleting it ends that.

Liability

To the extent the law allows, the service is not liable for anything arising out of its use, including lost work, lost data and a test suite that failed because a mock did not answer. The service is free, and that is the trade.

Privacy

What is stored about you and which cookies are set is covered in the privacy policy.

Changes and contact

These terms can change, and the date at the top is the one that counts. Continuing to use the service after a change means accepting it. Questions go to ngocdang.dev@gmail.com.
