Arazzo Engine – Overview¶

Arazzo Engine is the official open-source toolkit for the Arazzo Specification, an OpenAPI Initiative standard for orchestrating complex, multi-API workflows.

While the OpenAPI Specification (OAS) describes single APIs, Arazzo defines a standard, language-agnostic way to chain calls across multiple APIs into a workflow.

Why Arazzo?¶

Arazzo makes multi-API automation:

• Readable — human- and machine-readable workflow definitions
• Deterministic — predictable execution for automation and AI agents
• Standardized — backed by the OpenAPI Initiative and the Linux Foundation

Use cases: - Interactive workflow documentation - Automated testing and QA - SDK and code generation - Deterministic API invocation by agents

What is Arazzo Engine?¶

The Arazzo Engine is an implementation toolkit for the Arazzo Specification. It provides libraries and tools to execute, validate, and work with Arazzo workflows.

Today:¶

• Arazzo Runner – CLI + Python library for executing workflows

Planned:¶

• Workflow validators
• Visual workflow browser
• SDK/code generators
