fetch_wisdomtree_nav_history(ticker, *, api_key=None, session=None, api_url='https://dataspanapi.wisdomtree.com/funddetails/nav/')

Fetch official current and historical NAV observations.

The request uses WisdomTree’s documented history=True query. It only accepts explicit NAV/date fields and fails closed when the provider changes its response shape, so an unknown response can never silently become a one-dollar estimate.

Parameters

ticker (str) – WisdomTree fund ticker, e.g. WTGXX.
api_key (Optional[str]) – DataSpan key or WISDOMTREE_DATASPAN_API_KEY.
session (Optional[requests.sessions.Session]) – Optional requests session for tests and connection reuse.
api_url (str) – Endpoint override for tests.

Returns

Chronologically sorted official NAV observations.

Raises

WisdomTreeAPIError – If credentials, HTTP response or fields are invalid.

Return type

collections.abc.Iterator[eth_defi.tokenised_fund.wisdomtree.nav.WisdomTreeNAVPoint]
