Hikigai SDKs
Two product SDKs in Python and Node.js: deploy agents with AgentSDK, invoke them from apps with AppSDK (text, stream, live audio, speech, rooms).
Which SDK do I need?
AgentSDK — build & deploy
- Create single agents or Sequential / Parallel / Loop workflows
- Configure modalities (text, audio, …), tools, schemas, cloud
- Set leaf
live_handofffor live pipelines - Manage versions, jobs, storage, rooms from the builder side
AppSDK — run in your product
invoke/streamfor text chatlive()for bidirectional audio / live agents- Speech translate & transcribe, sessions, rooms, identity
- Works with any deployed agent (including workflow roots)
Typical flow: deploy with AgentSDK → call with AppSDK (or AgentSDK invoke while developing).
