Agora

Agora provides SDKs for embedding real-time video, voice, and interactive streaming directly into applications — used by Clubhouse (voice), online education platforms, and telemedicine apps. For agents, the REST API enables: generating RTC tokens for users joining channels (required for client SDK auth), starting/stopping cloud recording of sessions, querying active channel membership, and moderating channels (kicking users, muting). The primary RTC functionality runs in client SDKs (Web, iOS, Android, Flutter, Unity); the REST API is the control plane for token provisioning, recording, and channel lifecycle. HMAC auth on REST. Confidence is docs-derived.

REST API at api.agora.io. Resources: channels, users, cloud_recording, token_generation. POST /v1/projects/{appId}/rtc/{channelName}/uid/{uid}/role/{role}/token generates an RTC token for a user joining a channel. POST /v1/apps/{appId}/cloud_recording/acquire → start → query → stop for cloud recording lifecycle. GET /v1/channel/user/list/{appId}/{channelName} lists active channel members. DELETE /v1/kicking-rule adds moderation rules for a channel. Response payloads are JSON. Token generation is synchronous; recording is async with status polling.

REST API uses HTTP Basic Auth with Agora Customer ID and Customer Secret (base64-encoded). Customer credentials from Agora Console → RESTful API. RTC SDK connections use dynamic tokens generated by the REST API — tokens are time-limited (default 24h) and encode user UID, channel, and role (publisher/subscriber). Token server required for production (agent-side token generation using app ID + certificate via Agora Token SDK). HTTPS enforced.

Standard HTTP status codes with JSON error bodies (code, reason). 401 for invalid credentials, 403 for invalid app ID, 404 for missing channel. Cloud recording errors: resourceId expiry (acquire → start must happen within 5 min), S3 bucket configuration errors. Token validation failure surfaces as SDK error code (RtcEngine error). Recording status polling returns status code (4=active, 5=exiting). Agora platform uptime at status.agora.io. Regional edge nodes for low-latency global connectivity.

docs.agora.io provides SDK guides for all supported platforms (Web, iOS, Android, Flutter, Unity, Electron), REST API reference (token generation, cloud recording, channel management), migration guides between SDK versions, and implementation tutorials for common use cases (1-on-1 video, group call, live streaming). Documentation is comprehensive. Getting started requires an Agora account and App ID (free up to 10,000 minutes/month). Token server implementation examples provided. Community support via Agora developer community.
