I seem to be missing the feature that made EC and EM so popular: their own API for integration into other apps/services.
Are you planning on adding something alike?

I got api/item.xml and api/item.json working, but I'm not sure how to calculate the following:
- median
- kurtosis
- skew
- variance
- standard_deviation
- simulated
More than you perhaps ever wanted to know about statistics: http://en.wikipedia.org/wiki/Statistics.

Sort of, it seems. For me, the closing </xml> tag is missing.
The query (typeID 24702 is the Hurricane) http://eve-marketdata.com/api/item.xml?type_ids=24702 returns
<?xml version='1.0' encoding='utf-8' ?>
<evemetrics api_version='2.0'>

BTW, is there another place/way to provide feedback to you which you prefer over the EO forums?

Erhm ... yes ... of course.
Obviously coffee level wasn't high enough this morning, when I wrote that ...

Any chance you might make an API out of this like eve central has and eve metrics had?
He has already, that's what we're talking about with that MIME type stuff he needs to correct in the previous postings.
In theory it is similar to EM's API (so you only have to change the domain name for your query, i.e. Tritanium would be http://eve-marketdata.com/api/item.xml?type_ids=34.

Content-type's: fixed, now return as application/xml and application/json. Regarding formatting, the goal is to have it the exact same as eve-metrics for easy porting for people.
Thank you very much.
Another question: is there a limit for the number of items we can query with one call we need to be aware of? I.e. max 10/100/1000 different typeIDs in one query?

I've also decided to discontinue the item.xml/json api. I think that 99% of the people using it are only getting the average price, so that they can update their killboard, etc. However it provides far more info, which is CPU intensive. Therefore, I'm going to kill off that program, and people will have to update their code to use one of these new API's:
- http://eve-marketdata.com/developers/item.php for one item lookup
- http://eve-marketdata.com/developers/items.php for multiple
Not sure why you did that.
1) Two different URLs for the same purpose? This way you have to keep two scripts up tp date. Besides, you're already doing the parameter parsing with the second one (multiple items). The single item (single value) is just a special case of multiple items.
2) In terms of (output) format: is that the final result we're getting there already? Because that seems to be some kind of home-brewn result format. Are you planning to return something more standard (like the good old XML)?

4) XML/JSON formats: if you find any specific errors, let me know. Personally I don't use them. Keep in mind that I can no longer access the eve-metrics API, so I'm not sure exactly how they did it.
First, the announced items.php doesn't seem to exist: http://eve-marketdata.com/api/items.php?type_ids=34 results in a 404.
Whereas http://eve-marketdata.com/api/item.php?type_ids=34 works, but returns a format I'm nor familiar with:
\ntype_id\tbuy\tmin\tmax\tmedian\taverage\tstd_dev\[...]
34
buy0.013.42.41.8621828514751542462764.62665
sell0.013.421.862182851475150.45284745607815
Content type of the above: text/plain
Ah, I see, there's item_prices.xml which just holds a "price"
Now I'm really confused. Why can't you return the same amount of information in the XML (I guess JSON has the same issue) like you do in the item.php?
I'd really appretiate your efforts and I'd love to add your API to EWA, but I guess I'll wait until the "dust has settled" with the API stuff and a stable solution/format has been established.
