One account. Every library.

Your free ElkassabgiData account works across every Elkassabgi data library — hfdatalibrary.com (1-minute US equities), econdatalibrary.com (global economic & financial data), and every future database — with the same login and the same API key. Register once, download everywhere.

Registration takes a minute (email or Google/ORCID) and is hosted on the family's account server. Your key works here the moment you have it.

Your personal MCP connect URL (paste into Claude/Cursor — key included):

Use the key on any library, e.g.:
curl -H "X-API-Key: YOUR_KEY" "https://econdl-api.elkassabgi.workers.dev/v1/series/worldbank_wdi%3ASP.POP.TOTL.csv"
or in Python: econdl.HttpClient(BASE, api_key="YOUR_KEY") (also reads $ECONDL_API_KEY / $HFDL_API_KEY).

Accounts are stored once, centrally, for the whole ElkassabgiData family — registering here or on hfdatalibrary.com creates the SAME account. Manage details, regenerate keys, or delete your account any time at your account page.
