What it returns

One US crypto exchange-traded fund, day by day: its closing share price, net asset value per share, the premium (positive) or discount (negative) between them, shares outstanding, net assets and the coins it holds. Oldest first, the newest limit days. A fund's history can have gaps and can end well before today; date says which day each figure is for. Not scoped to any chain. A ticker no tracked fund has answers 404.

Chains

This endpoint is not tied to a chain: it takes no chain in its request.
