I wrote a tool to compute the value of a loot log so I can easily give payouts to my fleet. It uses data from eve-central that is cached in my DB since eve-central goes down periodically. A couple days ago I uploaded a loot log and my tool was reporting 0.00 ISK for a few items. As I debugged I found that eve-central had no buy orders listed for those items. I looked over at http://www.jitonomic.com and it had values listed so I manually entered them into my DB around 1:00AM so I could payout my fleet and go to bed.
On to the question... What is the most frequently updated and most reliable site for pulling market data via an API?
Thanks

I guess at the end you better have to check several sites for a price.
- eve-central.com
- jitonomic.com
- eve-marketdata.com
you should get results for those.
Just take the average of those 3 sites and you should be kinda accurate

I'm thinking along those lines too. It is a bit of a pain and I better turn my quick and dirty code into proper software before I attempt such a thing.

Or you can just sit an alt in whatever region you care about the prices and have the price uploader for one of the sites do its work to make sure they have up to date prices.

the price data used for this and that and EVE Asset Manager and probably a killboard or two can be found in batches here.
batches are grouped in 7 and 30 day temporal scopes, and by region / connectedhighsec (chs) / eve-global (all).
the processing works better on high-volume items. pay attention to the volume information in the rows.
and a "first" that is older than 7 or 30 days indicates this is not the freshest data.
on the narrower temporal or spatial scopes, less fresh data will be available.
the format is mostly the same as eve-api xml-rowset.
most people interested in pricing data for their app probably already have a parser that can be reused for this.
those are actual static files, updated several times a day, performance and availability of the http interface should not be an issue.
not even if evemon decided to use the data, without caching.
intended use is anything that prefers conservative stable longterm pricing over specific order-oriented data.
personally, i use the 30d-chs.
as usual, feedback and feature requests welcome.

eve-central has the biggest database, but sometimes it provides false data (orders which are 2 years old).
eve-marketdata.com has a little bit small database, but on the other hand it's more reliable
Personaly i merged those both database and use pricing from both sources on my website :)

That is very interesting. Who maintains this data? How reliable is the pricing?
For my use-case I'm determining the value of a bunch of sleeper loot and paying the members of my fleet. I usually don't get out to empire to sell the loot but once every week or two. If the data in those files is accurate enough to keep me from overpaying I'll use it. It would be nicer than making individual queries to eve-central.

If it helps, I'm regularly running a market data aggregator for marketGroupIDs (1145,1146,1148,1149,1150), which is sleeper stuff and gases/polymers, and am uploading that to eve-central once in a while.
Also you can query a list of typeIDs from eve-central, no need for individual queries.

I didn't know that. That would definitely help streamline my code. Thanks.

Agreed. Very interesting, and a lot more useful in many cases! Is it you (Jercy) who put in the work behind this? Like Turk, I'm just wondering where the data actually comes from before I start using it. Is it processed from any/all of the other mentioned sites or is it something you (or someone else) maintains yourself? |
