What is API (Application Programming Interface)?
API (Application Programming Interface) — A set of protocols that allows different software systems, such as enterprise software and AI models, to communicate.
In the AI context, APIs allow your applications to send prompts to AI models and receive responses programmatically. Most enterprise AI adoption starts with API integration — connecting existing software to cloud-hosted models like GPT-4 or Claude.
Frequently Asked Questions
Do I need to build my own AI model?
Usually no. Most businesses access AI through APIs provided by OpenAI, Anthropic, Google, or open-source model hosts. Custom model training is only needed for highly specialized use cases.
Are AI APIs secure?
Reputable providers encrypt data in transit and at rest. For sensitive data, look for providers offering data processing agreements, SOC 2 compliance, and zero-retention policies.
How are AI APIs priced?
Most charge per token processed — both input and output tokens count. Costs range from $0.10 to $30+ per million tokens depending on the model size and provider.
