OpenAPIHub
OpenAPIHub is an API marketplace and management platform where teams publish, discover, and monetize internal or third-party REST APIs behind a shared developer portal and sandbox. Each listed API runs behind its own per-provider gateway rather than one fixed host, so there is no single origin to CORS-probe; calling any listed API needs a key issued from the platform's Developer Admin Portal. Browsing and sandbox-testing APIs on the public hub is free, while turning the platform into a branded marketplace (the FabriXAPI product) is a paid enterprise tier.

Authorization: <key> - The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Stored keyNo key stored
Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
