Public dollar-funding evidence with source dates kept
What it is
An open-source research layer assembles US dollar-funding, foreign-exchange reference, and capital-market observations from public sources such as FRED, the New York Fed, Treasury fiscal data, and the CFTC. Python, R, and JavaScript clients, and a hosted read-only endpoint for assistants, return those observations with their source dates, and missing or restricted series stay labeled instead of being filled forward. Analysts and agents who are studying money-market stress, and not sending orders, are the audience. The layer is a narrow evidence view with coverage gaps left visible, not a full-market quote service or an execution venue, and some heavier calls require an account while the public read-only tools do not.
