Why Use Rev API?

Our API clients value fast turnaround time. While turnaround times vary by total audio length and service, we generally can return transcripts within 6 hours for orders under 10 minutes, and within 12 hours for orders of 30 minutes or less. Captions generally require 24 hours for orders under 30 minutes.
Our transcriptions and captions are among the best in the industry. We achieve this by only accepting the best transcriptionists and captioners from around the globe onto our team. Also, each audio or video is transcribed by a single person from start to end, ensuring consistency and quality.
Simple Pricing
The pricing for basic Transcription and Captions orders is simple: Minimum $1.00 per audio or video recording, then rounded up to the nearest second using $1.00 per minute pricing. Two examples:
  1. Audio recording of 45 seconds would be priced at $1.00, since we have a $1.00 minimum.
  2. Audio recording of 5 minutes and 20 seconds would be priced at 5.34 minutes x $1.00/minute = $5.34.
For Transcription we also offer two add-on services: time stamps and verbatim. These services cost an additional $0.25 per minute each. The costs for time stamps and verbatim follow the same rules as the basic transcription pricing. i.e., there is a minimum $0.25 charge and the prices are rounded up to the nearest second.
Powerful Features
  • Upload your audio/video files to our server, or we can retrieve them from an S3 bucket or public URL
  • Download finished transcripts as Word, PDF, plain text or JSON. Captions available in many formats.
  • Define webhooks to receive progress notifications for your orders
  • Communicate with our API securely over SSL, using JSON or XML
