Hi @eikon11 ,

Thank you for your question. You may be able to get the ratings using the Search capaibilities of RD Library for Python.

ratings = rd.discovery.search(
    view = rd.discovery.Views.MUNICIPAL_INSTRUMENTS,
    query = '613340Q27',
    select = "CUSIP, Ratings"
)
ratings['Ratings'].values

Hope this helps.

Best regards,
