How to pull bond data from GOVSRCH using Codebook?

Hi, I would like to pull bond data from the GOVSRCH universe.


I have used the Codebook tutorial to pull Enterprise Value data from 3 universes as below:

df = rd.get_data(universe=['LSEG.L', 'VOD.L', 'GOOGL'], fields=['TR.EV','TR.EVToSales'])


From the filters, it seems that GOVSRCH like it is a universe on it's own. govsrch-universe.png

So when attempting to pull a specific bond's data, for example GOOGL, I have tried searching with the Preferred RIC:


df = rd.get_data( universe = 'GOVSRCH', fields = ['02079KAB3='], parameters = ['ISIN']

This results in the following error:

Failure sending request with <refinitiv.data.content.fundamental_and_reference.Definition object at 0x7f57140dd340 {universe='['GOVSRCH']', fields='['TR.RIC']', parameters='['Coupon']', row_headers='None'}>

    raise ValueError(f"Arg parameters must be a dictionary")
ValueError: Arg parameters must be a dictionary

I also get a similar error when searching via the ISIN


How do I pull bond data using Codebook? Any assistance is greatly appreciated, thank you in advance.

Hi @oscar.guitet ,


Thank you for your question. You can't use GOVSRCH as universe in your request unfortunately.

Is all the fields you are after exist in your GOVSRCH output? If so, the best way I could think of is using Export query functionality of the Workspace:

Then a new window appears and clicking on the Codebook field you will get a python query with search capabilities which will allow you returning the same values you see in GOVSRCH via an API call:

In case you want other fields not available in GOVSRCH or you want time series data, we can retrieve the rics via search query and can request the fields/series via rd.get_data/rd.get_history function. Happy to help you on that if necessary.


Hope this was helpful. Please feel free to let me know should you have any further question.


Best regards,

Haykaz

Thank you very much for your response!


A follow-up if you don't mind:

Is there a way of searching the GOVSRCH environment for specific ISINs? I have an example export query below for ISIN US45766X2053. Is this a limitation of the license I am using? Thank you in advance.


df =rd.discovery.search(

view = rd.discovery.Views.GOV_CORP_INSTRUMENTS,

top = 100,

filter = "((DbType eq 'GOVT' or DbType eq 'CORP' or DbType eq 'AGNC' or DbType eq 'OMUN' or DbType eq 'OTHR') and IsActive eq true and (ISIN eq 'US45766X2053'))",

select = "RIC,EJVAssetID,DTSubjectName,BusinessEntity,PI,SearchAllCategoryv3,SearchAllCategoryv2,SearchAllCategory,DBSTicker,CouponRate,MaturityDate,IssueDate,ISIN,RCSCurrencyLeaf,RCSCountryLeaf,DbTypeDescription,InstrumentTypeDescription,RCSCouponTypeGenealogy,FaceIssuedUSD,RCSBondGradeLeaf"

Hi @oscar.guitet

You provided an example query that looks correct. For example, this is the result when I applied your request:

1681245620870.png

It's unclear what limitation you ran into? Are you suggesting there is a limitation of not being able to specify the ISIN within the GOVSRCH app within the desktop? You can specify the ISIN.

Or did you not get a result when you tried to execute your code segment?
