API: Definition & Explanation
An API (Application Programming Interface) is a standardized interface that allows software systems to exchange data and functionality. In the AI space, companies like OpenAI, Anthropic, and Google offer their LLM capabilities via APIs, enabling developers to easily integrate AI features into their own applications. Delivered in formats such as REST API and GraphQL, these APIs provide access to text generation, image generation, speech synthesis, translation, embedding generation, and more. Pricing is typically usage-based, charged per token or per request. By leveraging APIs, developers can build chatbots like ChatGPT, automate content generation, and create data analysis pipelines. No-code tools like Zapier AI and Make even allow non-programmers to connect APIs without writing any code.
