What is API Access?

Definition

The ability to programmatically interact with a subscription service through its Application Programming Interface.

Understanding API Access

API access is a key differentiator between subscription tiers. Many services restrict API access to higher-priced plans. APIs enable automation, custom integrations, and building on top of a platform.

For example, Slack's API allows custom bots, Stripe's API powers payment processing, and OpenAI's API enables AI integration. API pricing often uses usage-based models with rate limits. When evaluating subscriptions for development or business use, check API availability, documentation quality, rate limits, and whether API access requires a premium tier.
