In a developer portal, what does 'subscribing to an API' typically mean?
In portal contexts, subscribing to an API means an API consumer (developer or application) registers for access — typically selecting a usage plan, receiving credentials, and gaining the right to call the API within defined limits.

An API listing in a developer portal shows status: 'End-of-Life.' What should API consumers do?
'End-of-Life' (EOL) means the API has been fully deprecated and a shutdown date has been or will be set. Consumers should migrate to the replacement API as soon as possible. The portal typically provides migration guides alongside EOL notices.

What is an 'API consumer' in developer portal terminology?
An API consumer is any developer, application, or team that uses the API. Developer portals are designed around the consumer experience — making discovery, onboarding, and ongoing use as smooth as possible.

A portal page says: 'Explore our APIs.' What is this page typically for?
'Explore our APIs' is the entry point to the API catalog — a searchable, filterable listing of all available APIs with descriptions, versioning, status labels (active/deprecated), and links to documentation. It is the discovery interface for API consumers.

What does 'API key issuance' refer to in a developer portal?
API key issuance is the provisioning step after subscription — the portal generates unique credentials that the developer includes in API calls to authenticate. Portals typically allow developers to view, rotate, and revoke their keys.
