ElkassabgiData

Search the Econ Data Library catalog (billions of series from hundreds of sources: national accounts, prices, trade, labor, energy, markets…). Free, no key needed. Returns series ids usable with get_econ_series. Page with offset; lang returns source-official translated titles where the publisher provides them.

Live per-source update status straight from the automated updater's ledger: last successful update, data frontier, and honest stale/failure flags (dates are NEVER fabricated — a silent upstream outage shows here as stale, not papered over). Free.

A citable bundle manifest (Frictionless data package) for several econ series - up to 50 explicit ids, or every series of one small source (up to 1,000 series): the per-series download URLs grouped by source, each source's attribution and licence, and any id that could not be resolved (reported, never dropped). The URLs serve the CURRENT data - this is not a frozen vintage. Free, no key needed for the manifest; downloading the URLs needs the key.

Authenticated download instructions for HF Data Library's 1-minute OHLCV bars (per-ticker US stocks/ETFs from IEX Exchange HIST, 2022-03-07 to the present; parquet or csv) or the 25 pre-computed academic variables.

Works with the same ElkassabgiData key.
