from Hacker News

Since the number of 2nd hand phone purchases is steadily increasing, and the number of reported stolen devices is doing more than that, we decided to "slackify" this endpoint.

Identify any phone based on its IMEI number.

Check if it is blacklisted against over 150 network operators from 57 countries (GSMA Data + Direct MVNO Connections + Proprietary Algo)

• /whatphone Get specs on a phone based on its IMEI/MEID

• /isblacklisted Check whether a phone is blacklisted

• /isatt Did the phone originally come from AT&T

• /how Help and list of more commands!

/whatphone and /isatt commands are unlimited. /isblacklisted checks have an underlying cost, so they are limited to 10.
