search_econ_seriesread-onlySearch the Econ Data Library catalog (billions of series from hundreds of sources: national accounts, prices, trade, labor, energy, marketsâ¦). 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.

get_data_freshnessread-onlyLive 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 â a silent upstream outage shows here as stale, not papered over). Free.

Parquet, full-history files fetched by YOUR code, not returned inline. Works with the same ElkassabgiData key as every family library.
