Question
How does the Live Captions API pricing work?
Applies To
- Live Captions API
Answer
Live Captions is charged based on the number of audio streams (or StreamIDs) that publish captions.
- Pricing is based on the duration of each participant’s audio being sent to a transcription end point @ $0.025 per minute/participant.
- Pricing does not depend on the number of participants subscribing to captions
- Unit of metric - Live Captions Minutes

(A) participant in a call
(A) publishes captions
(A) subscribes to captions of (A)
- E.g. 30 minutes call
- Publish time (A): 01 minutes and Stop time (A): 28 minutes
- Total live captions minutes: 27 minutes
Case 2
(A) & (B) are participants in a call
(A) publishes captions
(B) publishes captions
- E.g. 30 minutes call
- Publish time (A): 01 minutes and Stop time (A): 28 minutes
- Total for (A): 27 minutes
- Publish time (B) : 00 minutes and Stop time (B) : 30 minutes
- Total for (B): 30 minutes
- Total live captions minutes for A&B = 27+30 minutes
