We would like to monitor a large area through the real-time API on Instagram. But unfortunately we quickly hit the max. 30 subscriptions roof. This will limit us to a 30 x 5 km radius area to monitor.
Any thoughts on how to monitor larger areas or have you heard of people getting a higher rate limit?
To monitor larger area, you can try to subscribe to location, instead of geography which is based on geolocation coordinates.
Steps could be as following:
easiest way to get the location, is to check its Foursquare id (this one for Hong Kong Airport),
map it to Instagram object_id (use Instagram API Console),
subscribe to this location using the object_id you just fetched
(check Location Subscription paragraph here
EDIT:
Regarding monitoring larger area - I'm using cluster of the accounts, and subscribing to set of locations, to not reach the limit. Works fine for couple months already.
