VideoSDK

Adding live audio and video calls, streaming or an AI voice agent to your own app is what VideoSDK is built for.

VideoSDK is a developer API and SDK platform for low-latency real-time communication, with speech-to-text, text-to-speech and transcription services available as add-ons.

Audio-video calls run on a global mesh network with latency under 80ms.

Pricing is usage-based.

Audio calls cost $0.0006 per participant-minute, video calls $0.003, and live streaming $0.0015 per viewer-minute.

Add-ons are billed separately: meeting recording is $0.015 per recorded minute, real-time transcription $0.02 per minute, post-call transcription $0.0045, and prompt-based summaries $0.004 per recording minute.

The free plan gives you 10,000 minutes a month for conferencing and streaming plus 300 minutes for add-ons, with no credit card and Discord community support.

That is enough to build and test a prototype.

Enterprise plans start at 1M minutes and add discounted rates, HIPAA, SOC-2 and CERT-In compliance, a 99.99% uptime SLA, geo-fencing and a dedicated cloud region.
