Documentation for eth_defi.tokenised_fund.securitize.chronicle.fetch_chronicle_price_history function.

fetch_chronicle_price_history(feed, history_url, *, timeout=20.0)

Fetch Chronicle Proof of Asset NAV history from an explicit JSON URL.

The caller must supply the source URL because Chronicle has not documented a stable public API endpoint for the STAC dashboard. The response may be a list directly or an envelope containing a data list.

Parameters

• feed (eth_defi.tokenised_fund.securitize.chronicle.ChronicleSecuritizeFeed) – Reviewed Chronicle product metadata. Retained for audit-friendly call sites and future feed-specific validation.

• history_url (str) – Public JSON history URL exported by Chronicle.

• timeout (float) – HTTP request timeout in seconds.

Returns

Oldest-to-newest distinct signed observations.

Raises

ChronicleAPIError – If the source response does not contain a supported history list.

Return type

collections.abc.Iterator[eth_defi.tokenised_fund.securitize.chronicle.ChroniclePricePoint]
