Real-time L1 data through API supporting > 1000 symbols

Where can one obtain real-time L1 bid/ask/size/last/etc quotes via an API? I don't want some retail-level solution or some Excel DDE thing.

Requirements:
NYSE/NASDAQ/AMEX, and CME if available
L1 bid/ask/size/time and sales/etc
> 1000 symbol registration
real-time streaming data
API

So far I'm aware of nanex.net (NxCore), are there any other similar options, perhaps for cheaper than the $700/month Nanex is asking?

Both DTN IQFeed and Townsend Analytics (RealTick) once allowed you to "upgrade" their services to go something over 1000 symbols; not sure if this is the case anymore.

Where can I find details about your Quotesource product?
Is the API freely available for studying & testing?

What a complicated process to get basic info about a product.
Never mind, I did what you said, using a fake name of course :-)
 
they never got back to me either (esignal enterprise feed). this was last year. i even called a local rep which i scrounged off one of their company directory's. spoke to him, had an hour chat. he never got back to me either, even after multiple voice mails (i had money to spend as well). don't bother.

decent retail product though.
