hacking_the API

all_results

run a call using params, 
from that call, parse and store only the factual id and the POI name. do the page/offset thing to get 500 max records, in chunks of 50. Store these together
make another call with the same params, except filter by POI name NOTIN {our stored list} (the factual api dosen't let you filter this way by factual-id, boo)
see if we can get that in chunks of 500
do this until no new results are returned

store that in all results
this seems like it would have to go in order 

OR

return a count (https://github.com/Factual/factual-nodejs-driver#facets) given provided params 
count = 1475
params = params

run a call, get 50 results, store this in all_results (or whatever)
run another call, get 50 results, see if any of these results match the 50 we already have. if not, add them. 
this comparison could be done via hashing/checksumming or some other fancy computer science thing
do this until # of records in all_results == count
_prepare these calls all at once/do a bunch at a time to make it go faster_
