The objective is to allow manualy add IP into CF whitelist to check site from geo restricted regions. For examples we block all customers form Ukraine as not relevant country, but we work from Ukraine. It's ok to whitelist office IP. But if you need some urjent check from mobile phone it would be a problem. To allow fast IP whitelist small opt-in form was created.

Depolyed to Vercel.com, their FaaS used for connecting to CF API.

• /api/add: will add yours ip to whitelist, in responce

{"listed":true,"ip":"x.x.x.x"}

or

{"listed":false,"err":"some error"}

• /api/check: will return yours ip status, like is it already listed or not (permanent listing also will result true)

{"listed":true,"ip":"x.x.x.x"}

or

{"listed":false,"err":"some error"}

• /api/clean: this method used for removing all temp ip's from cloudflare. It should be called in desired amount of time.

{"cleaned":true,"count":10}

or

{"cleaned":false,"err":"some error"}

There is no cron avalible at vercel. Read an issue That's why we use assertible.com, service for api monitoring as a solution for triggering /api/clean/ once a day. Also it validates amount of temp records added every day, and if amount will be suspicios will fire email alert.

Unfortunately nodejs API for CF is not complete. Thats why PR from original repo currently used: cloudflare/node-cloudflare#78
