API Reference

Overview

The iwy API provides everything you need to create and deploy conversational AI agents. There are two types of agents you can create:

Single-Use Agents

Created via API, activated once, then expires. Perfect for personalized, per-session experiences.

Permanent Agents

Created via API or dashboard, reusable forever. Configure anytime at dashboard.iwy.ai.

Both types are production-ready and interchangeable. Use the same widgets and session APIs with either type. Choose based on your use case—many production systems use both.

Authentication

All API endpoints require a Bearer token.

Authorization: Bearer YOUR_API_KEY

Get your API key from app.iwy.ai/settings.

Core Endpoints

These are the three endpoints you’ll use most often:

Endpoint	Purpose
`POST /ephemeral-agent`	Create a single-use agent
`POST /agent`	Create a permanent agent
`POST /start-agent-session`	Start a video call session

Using iwy widgets? The <live-avatar> widget and meet.iwy.ai already call /start-agent-session for you automatically. You only need this endpoint if you’re building a custom integration with the Daily.co SDK.

Single-Use vs Permanent Agents

What's the difference?

Single-Use Agents are created through the API and can only be activated once. After their first session ends (or the TTL expires), the agent ID becomes invalid. They don’t appear in your dashboard.Permanent Agents persist in your account forever. The same agent ID can be used for unlimited sessions. You can edit them anytime at dashboard.iwy.ai or via the API.

Feature	Single-Use	Permanent
Sessions per agent	1	Unlimited
Visible in dashboard	No	Yes
Editable after creation	No	Yes
Auto-expires	Yes (TTL)	No

Which should I use?

Both are production-ready. Choose based on your architecture:

Use Case	Recommended
Same agent for all users	Permanent
Personalized agent per user/session	Single-Use
Want to edit config in dashboard	Permanent
Config generated from your database	Single-Use
White-label / multi-tenant apps	Single-Use
Quick prototyping and testing	Permanent

Many production systems use both: permanent agents for core experiences, single-use agents for personalization.

Can I use them interchangeably?

Yes! Both agent types work identically with:

All iwy widgets (<live-avatar>, etc.)
meet.iwy.ai hosted pages
The /start-agent-session API
Tool integrations

The only difference is lifecycle management—single-use agents expire, permanent agents persist.

What happens after a single-use agent is activated?

Once a session starts with a single-use agent:

The agent becomes “active” for that session
When the session ends, the agent expires immediately
Any further attempts to use that agent ID will fail

If no session ever starts, the agent expires after its TTL (time-to-live).

How do I convert between types?

You can’t convert directly, but you can reuse configurations:

Single-Use → Permanent: Use the same configuration object with POST /agent
Permanent → Single-Use: Fetch config with GET /agent/{id}, then use it with POST /ephemeral-agent

This is useful for prototyping in the dashboard, then deploying as single-use agents.

Single-Use Agents

Create dynamic agents that activate once and then expire. Ideal for personalized, per-session experiences.

/ephemeral-agent

You probably don’t need this endpoint directly. The <live-avatar> widget and meet.iwy.ai call this automatically. Only use this if you’re building a custom integration with the Daily.co SDK.

Start Agent Session

POST

/start-agent-session

Starts a video call session with an agent. Returns Daily.co connection details.

Request Body

agentId

string

required

Agent UUID (works with both single-use and permanent agents), or "demo" for a demo session
