Public APIs
A catalog of open data and official API portals for student projects — government open data, Wikidata, weather, and curated directories. Use only documented, legal endpoints; no scraping gray areas. You can navigate, find Hub (all catalogs), and browse Sister repos.
Disclaimer: Keys, quotas, and ToS change. Read each provider’s terms before shipping a project.
