Using my API key efficiently

I'm writing a script for Java, which uses my API key to grab information. However, I need to grab a lot of information, right now I use my API key twice for every item in the game in fact, once to search all bazaars and once to search the item market. If you have experience with this and know how to cut this down to once or twice each run of the program, I would greatly appreciate your help.

Btw, I'm writing in Eclipse with Maven

https://api.torn.com/market/458?selections=bazaar,itemmarket&key=XXXX



458 = Item ID

XXXX = your API key

I realized I could use the bazaar and item market at the same time already, thank you. I'm taking a computer science course and just playing with some ways to apply what I'm learning. I also set it to only search one item per second so it doesn't request too many per minute. It's unfortunate that searching bazaars and the market is the only way to send fewer requests, calling every item at once would be useful

store your requests as you go thoughout the day, and reference the storage as needed, updating it when the info gets too old

speed isnt your friend here

I think what ur looking for is, after an initial pull of bulk data, a subset of change. thats what this post asks for:

API server load & bandwidth reduction query option

however, unlike its examples, you are looking for "removed" (or sold) items, which is not what the server current allows access to. They do however use that info to recalculate the "current value", so it must be retrievable. In the meantime u are stuck "doing it manually"

btw pulling 1x sec may not be so accurate, due to network latency, request processing, then data processing and not to mention the speed of ur network connection
