API access
Programmatic access to a model or tool so developers can integrate its capabilities into their own products and workflows.
Definition
An API exposes endpoints for tasks such as chat completion, image generation, or transcription, billed by usage and governed by rate limits and terms. Most AI companies offer APIs alongside consumer apps, and many tools in this directory add APIs for automation. SDKs wrap APIs in language-specific libraries.
Why it matters when choosing a tool
API availability decides whether a tool can be embedded in your systems or only used by hand.
