Daily.co REST API
Provides WebRTC video and audio infrastructure via REST API and client SDK, enabling agents to create rooms, issue access tokens, trigger cloud recording, and receive real-time transcription without managing media servers.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
API key is a long-lived credential scoped to a Daily domain — treat as a secret and never expose client-side. Meeting tokens provide fine-grained per-user capability control (is_owner, start_video_off, max_cam_streams, etc.). HIPAA BAA available. End-to-end encryption supported but opt-in per room.
⚡ Reliability
Best When
You need embeddable WebRTC video rooms that agents can provision and control via REST, especially in HIPAA-regulated or compliance-sensitive contexts.
Avoid When
Your use case is pure telephony (PSTN calls, SMS) or you need a fully self-hosted media server with no SaaS dependency.
Use Cases
- • Agent creates a Daily room on-demand for a scheduled customer support call and returns the room URL to a human operator
- • Agent issues meeting tokens with expiry and role (owner/attendee) to control who can join a telehealth session
- • Agent triggers cloud recording of an ongoing room and later retrieves the recording URL for archival or compliance
- • Agent enables live transcription on a room and receives webhook events with utterance text to log or act on in real time
- • Agent creates a HIPAA-eligible room with end-to-end encryption for a sensitive patient consultation workflow
Not For
- • Bulk SMS or voice call broadcasting — Daily is video/audio rooms only, not telephony
- • Large-scale webinar platforms with 500+ simultaneous viewers — use a dedicated streaming CDN instead
- • Agents that need only audio conferencing without any browser or SDK client on the other end
Interface
Authentication
REST API authenticated with a per-domain API key passed as a Bearer token. Room-level access for end users is controlled via meeting tokens (JWTs) generated server-side with Daily's API, carrying role (owner/attendee), expiry, and capability claims.
Pricing
Cloud recording, transcription, and live streaming are add-on costs beyond base participant-minutes. HIPAA Business Associate Agreement available on paid plans.
Agent Metadata
Known Gotchas
- ⚠ Meeting tokens must be generated server-side and expire quickly — agents must mint a fresh token before handing a room URL to a user, not reuse old tokens
- ⚠ Room URLs are stable but room 'privacy' setting (public vs private) must be set at creation time; changing it requires deleting and recreating the room
- ⚠ Cloud recording does not start automatically — agents must explicitly call the recording start endpoint after a participant joins, or configure auto-record at room creation
- ⚠ Webhook event delivery is best-effort with retries but not guaranteed exactly-once; agents processing transcription or recording-complete events should handle duplicate delivery
- ⚠ HIPAA-eligible configuration requires specific room properties (enable_prejoin_ui, enable_knocking, etc.) to be set deliberately — there is no single 'HIPAA mode' flag
