API.markdown
Unless otherwise mentioned, all the requests are HTML forms:
* `application/x-www-form-urlencoded`
* `multipart/form-data`
## browser requirement
Front-end should probably run on browsers newer than
* Firefox 21
* Chrome 27
* IE 10
because:
* They avoid [JSON hijacking][1].
It is suggested that front-end framework either refuse to work on a legacy browser, or (at least) alert users to possible security issues.
