OpenAPI Specification
The OpenAPI Specification (OAS), previously known as the Swagger Specification, is a specification for a programming language-agnostic, machine-readable interface definition language for describing, producing, consuming, and visualizing web services. OpenAPI documents describe API services and are represented in YAML or JSON formats.

When AI agents browse a site that doesn't publish machine-readable metadata or APIs, they fall back to scraping HTML, guessing endpoints, and retrying. That burns 5-100x more tokens per session and silently inflates the cost of every agent interaction. BotVisibility runs 55 automated checks across 5 levels.
