$ ruby how-threatened-is.rb "Pseudochazara euxina"

Pseudochazara euxina
IUCN Red List Status (updated 2009): EN - Endangered
--------------------------------------------------------------------------------

A very local and endemic species, restricted to fewer than five locations. The
population is reported in decline (Van Swaay & Warren, 1999: 15-25% decline in
25 years). Therefore it is listed as Endangered. This species is absent from the
EU state members and is therefore assessed as Not Evaluated at the EU27 level.

When searching for Cyclura cychlura this redirects to the entry of Cyclura cychlura ssp. inornata. However I want to find the entry for species ID 6034. Any ideas?

Is there any official documentation for the API?

@rhewitt22: In case you haven't already found it: The best thing google found is a 4 year old wiki: https://www.assembla.com/spaces/sis/wiki/Red_List_API

@rfc2616, others: The API documentation does not appear to cover the case of querying for JSON data by species ID. This is rather frustrating, since not all of the species names returned by the API can actually be converted into valid queries (e.g. Aplocheilichthys sp. nov. 'Naivasha'). (This is perhaps related to @Edild 's question too - did you ever find a solution?)

It would be great if there was a way to construct a query by species_id instead of taxon level, e.g. something like: http://api.iucnredlist.org/index/species_id/22823.json but clearly that doesn't work. Any ideas?
