Getting dividend yields for all NYSE stocks

Hi,

does anyone know if there is a way to accomplish this through some API, say IB, Yahoo? Doesn't work for Google finance

 

You get some numbers through Yahoo Finance web-api: http://www.jarloo.com/yahoo_finance/

Dividends
y: Dividend Yield
d: Dividend per Share
r1: Dividend Pay Date
q: Ex-Dividend Date

Not very certain how accurate or current these numbers are.

 

For the S&P500 (or anything else with traded futures) you can get the implied dividend of the basket by backing out interest rates from the discount or premium of the future to spot.

 

Why just NYSE? Seems like exchange-bias to me.

 

Not limited to NYSE, but it's just a problem statement. Anyway jarloo doesn't work.
