Three APIs for three specialized agents in your CrewAI Flows
The Scenario
CrewAI Flows is the enterprise architecture for multi-agent systems. A vocabulary instruction Flow has three agents: Agent 1 (Dictionary Specialist) looks up “innovation.” Agent 2 (Teacher) delivers a structured 5-phase lesson using the architect archetype. Agent 3 (Assessor) runs comprehension questions. CrewAI’s memory system remembers what the crew has taught. The knowledge graph coordinates handoffs. 44,000+ GitHub stars, 100,000+ certified developers.
Step 1 — Word Orb looks up the word
One API call returns a verified definition, translations, pronunciation audio, and etymology.

Why this matters for CrewAI
CrewAI Flows architecture — three Orb APIs as three agents in a production Flow with sequential, parallel, or conditional execution
CrewAI’s memory system (short-term, long-term, entity, contextual) + Orb’s knowledge graph = crews that never repeat vocabulary content
CrewAI AMP triggers (Gmail, Slack, Salesforce) enable automated vocabulary delivery — a daily Slack message with the word of the day, taught by the crew
100,000+ certified CrewAI developers can add vocabulary capabilities to any crew in minutes with the Orb Platform SDK
