Sam-
I have applied and currently in the same moderator-approval-limbo since a day after the
API was announced here.
I share your same curiosity as to what others are doing. I haven't done much (other
than what I have posted here), but if I do anything the first way to see it is on Github
(you can follow me on there if you use it at github.com/okiandrew). The second way to see
it is twitter (@okiAndrew). Hopefully both of these tools are not blocked for you.

Has anyone had any luck getting approved by the API developer forum? I've been in
moderator-approval-limbo for the last week and I'm curious what other people are
putting together.

In looking at http://www2.census.gov/acs2009_5yr/summaryfile/ACS_2005-2009_SF_Tech_Doc.pdf
pg 40, it shows B02001 is race. Unlike the SF1/SF3 documentation, it only lists that and
not the specific tables. In comparing it with AFF2, B02002_001E is table 1 estimate (the
total population). If you put 'M' instead of E, data is returned, that's the
MOE.
For example, try
http://thedataweb.rm.census.gov/data/2010/acs5?key={YOUR_KEY_HERE}&get=…
You should get a response of
[["B02001_001E","B02001_001M","B02001_002E","B02001_002M","NAME","state"],
["36637290","0","22392713","29506","California","06"],
["19229752","0","12764402","12714","New
York","36"]]
If you look at the ACS 2006-2010 estimates through Factfinder2, you will see that
B02001_001E is the total population (and no MOE is published for those), and B02001_002E
and B02001_002M matches the data for the white population and the MOE for those (see below
if you don't want to mess with AFF2).

The API appears to be unfinished. I can't seem to get any household data (not even
total households) pulled from SF1, SF3 returns an error (and we don't know if that
will ever be supported by the API), and there appears to be a limit of pulling 5 fields at
a time (hopefully they release that to allow us to pull at least 12 or 15). Also, I
applied to join the developer's forum and haven't heard anything back. I was able
to get a key to try some tests, though. Hopefully we'll hear and see more in the next
few weeks, as this looks pretty promising.

PS: If you'd rather pull tables with Python as opposed to through URL lines, take a
look at https://gist.github.com/3122936 . If you're on Windows and don't have
Cairoplot and GTK installed, you may want to remove the import for cairoplot and the very
last line and code around the rest. It is simple, but I'd expect people to take it
and change it to suit their own needs.

B02001 is Race, which includes population. 001E looks suspiciously like the sort of table
designator you find in the downloaded summary file version of the ACS 5 year data.
B02001_001 is the total population there, but I have no idea what the E is for.

Subject: [CTPP] API Request Table Codes
I've noticed that the table codes used in the API requests don't seem to match the
table codes used in the table master lists or in American Fact Finder. For example the ACS
5-year table number for "Total Population" is B01003, but in the examples of API
requests here<http://www.census.gov/developers/> the table number used to fetch
population statistics for California and New York is B02001_001E, which the master list
would have me believe is the table code for race (plus the "_001E" which I'm
mystified by).
Is there a separate list of table IDs that the API recognizes / am I using the wrong
lists?
