How is our API different to OpenHolidays?

OpenHolidays tells you when school breaks happen. PredictHQ tells you what to do about it. School holidays drive massive shifts in behavior — families travel, students stay home, foot traffic spikes. If you're not factoring these into your business operations, you're leaving revenue on the table.
