TL;DR: This is not even a proper API. It's incosistent and it's basically trash in terms of engineering. There are important reasons why it's so and I touched some of them below. The most important part is it's just a placeholder API. It's going to be available anyway, BUT I'm working on a much bigger thing that will replace this old stats hub and LRG2API as a result. I will update it to be more consistent in future, but it's not a priority for me. The whole point of this API's existance is to have access to the data to make some other apps related to it. That's also why there's no proper documentation, why LRG2 is not maintained anymore and so on: there are other priorities and working with all this mess is just not worth the time.

So here’s the deal.

I said a long time ago that I’m not really interested in reworking LRG2 codebase into something decent and I’d rather make something new. However I have a good amount of data and other reports now and I should provide an API to access this.

LRG2API is mostly reusing code from the main web view script (WV from this point). However it’s much more clean and has some additional features on top of that.

There’s no routing. It’s using a modline parser I was using for WV. Data in API essentially mirrors module structure from WV and you can just copy modline from here and get the same data from API.

Describing data structure for every single thing here may be too much and you’ll probably test the endpoint yourself first. The structure is pretty simple by itself and every valid modline returns the same data as its WV counterpart. However there are some unique things I’d like to mention some API-unique things here (and there will be a structure for it as well, marked by [EXCL]).

Ah, and another thing. The format of reports lacks consistency. There are a lot of reasons why it happened, but it doesn’t matter that much right now. What matters is you have to deal with it since most of data in this API are fetched from the reports directly. There’s also an endpoint that returns full report “as is”. It’s recommended to use if you need to perform a lot of requests (and from the raw report you can get virtually every single bit of data that I can). But in most cases it’s better to use specific API calls instead since LRG2API provides a bit of consistency and makes it less painful to work with the old reports’ format.

And another another thing. One of the “consistency” problems is numbers being strings all around the place. It actually has a reason to be like that in the reports and I don’t want to fix every single thing in API endpoints descriptors. You can handle it yourself, I believe in you, kiddo.

There’s also a note about versions format. It’s basically a number based on Opendota versions with a postfix to indicate specific lettered patch. For example, 4200 is 7.23(a), then 4201 is 7.23b, 4202 is 7.23c and so on.

Now it’s time to talk about methods

One major GET parameter is report. It specifies a tag of a report to load. If such report exists then GET mod is parsed. This is case one – Report is loaded. The second case is opposite and it has some unique endpoints.


  • (GET) league – report tag for report endpoints

  • (GET) gets – a comma-delimited list of parameters (for non-report endpoints)

  • (GET) mod – Modpath to execute. It’s readed from last to read to find the next specified method. Think of modline as of a path to a file with directory names. You can use / or - as separators.

    • Modline examples: heroes-positions-position_1.1, regions/region2/heroes/meta_graph
    • The modline if being read right to left so you can specify a very long modline, but as soon as it finds a correct endpoint, it gets executed regardless of everything else.
    • Modline can contain some parameters (described below as MODL). Modline parameters can be placed anywhere in modline.
  • (MODL) region# – sets region variable to # value (expected region codes listed in metadata)

  • (MODL) position_C.L – sets position to C.L code, where C is Core flag (0/1) and L is lane flag

  • (MODL) heroid# – sets heroid to # value (based on in-game hero IDs)

  • (MODL) playerd# – sets playerid to # value (steam userid 3 expected)

  • (MODL) team# – sets team to # value (expected dota team ID), alias teamid#

  • (MODL) itemid# – sets item to # value (expected dota item ID)

  • (GET) rep – report tag (for non-report endpoints)

  • (GET) pretty – flag, if it’s used response will be nicely formatted

  • (GET) desc – flag, adds report descriptor to the response if set

  • (GET) teamcard – flag, adds team card to the response if set

  • (GET) item_cat – comma delimited list of item categories, allowed values are `all`, `major`, `medium` (~1-2.5k gold items) and `early` (early game items), used only by items modules

It’s fairly simple to explain. It doesn’t have a structure and is used in summary-like modules (positions for example). It’s just an object without any fixed structure, every key corresponds for a value. That’s pretty much it.
