Daily.co Video API
Programmable video and voice calling API built on WebRTC. Provides REST APIs to create and manage rooms, prebuilt embeddable UI components, client SDKs for custom UI, server-side recording and transcription, and deep integration with real-time AI voice agents via the Pipecat framework.

⚙ Agent Friendliness
🔒 Security
DTLS-SRTP encrypts all media in transit. Meeting tokens enable fine-grained per-participant permissions. HIPAA BAA available on paid plans. SOC2 Type II certified. Room-level privacy settings control who can join without explicit token.
⚡ Reliability
Best When
You need to ship a video feature quickly using a prebuilt UI, or you are building an AI voice agent that needs to join or host real-time calls with low latency transcription and TTS integration via Pipecat.
Avoid When
Your use case is primarily large-scale one-to-many broadcasting, or you require a full-featured enterprise conferencing platform with scheduling, calendar integration, and meeting management built in.
Use Cases
- • Embedding video calls into web or mobile applications with a prebuilt UI in under 30 minutes using daily-js iframes
- • Building custom video experiences with fine-grained control via React hooks or vanilla JS SDK
- • Server-side recording and transcription of video sessions for compliance, coaching, or async review workflows
- • Deploying AI voice agents (LLM-backed) into calls using Daily's Pipecat integration for real-time conversational AI
- • Telehealth platforms requiring HIPAA-compliant video with waiting rooms and participant controls
Not For
- • High-concurrency live streaming to thousands of passive viewers (use HLS-based platforms instead)
- • Voice-only telephony with PSTN/SIP integration as a primary use case (use Twilio or Vonage)
- • Teams that need self-hosted open-source infrastructure with no vendor dependency
Interface
Authentication
API key authenticates REST API calls from your server. Meeting tokens (JWTs) control per-participant permissions in a room — e.g., whether they can start recording, screenshare, or are an owner. Tokens are short-lived and should be generated server-side. Never expose the API key to clients.
Pricing
Recording and transcription are add-ons billed per minute of recorded/transcribed content. AI voice agent minutes via Pipecat integration have separate compute pricing. Free tier is generous for prototyping.
Agent Metadata
Known Gotchas
- ⚠ Meeting tokens must include `room_name` matching the target room exactly — a token without room_name is a wildcard that can join any room in your domain, which is a security risk agents must avoid when generating user-scoped tokens
- ⚠ Room `exp` (expiry) and `nbf` (not-before) are Unix timestamps in seconds, not milliseconds — passing millisecond timestamps is a silent failure that creates rooms with nonsensical expiry times
- ⚠ Recording requires the recorder to be an owner-level participant; if your agent joins without an owner token, the recording API call will succeed but produce no output
- ⚠ Pipecat voice agent integration requires a separate Daily bot participant to join the room; the bot participant counts against participant-minute billing even during silence
- ⚠ Webhooks for recording completion fire after post-processing which can take 1-5 minutes after a call ends; polling the REST API for recording status is more reliable for time-sensitive workflows
- ⚠ The `daily-js` prebuilt iframe and the custom call object SDK are mutually exclusive in the same page context — switching between them mid-session requires a full page reload
