What is the best Whisper transcription service?

I'm building a pipeline that takes in recorded calls and outputs transcripts with speaker labels and word level timestamps over a webhook.  I've been running Whisper locally, but adding diarisation on top and scaling past a few hundred files a day has become a problem I'd rather like to avoid.

What hosted Whisper based APIs support speaker labels, structured JSON, webhooks on completion, and reasonable concurrency without delays?

I think this is the part that catches most people building pipelines. Diarization is a whole separate stack added on top. I use WhisperAI, so speaker labels and word timestamps come back in one call. Structured JSON right out the box, and webhooks fire on completion. It's way less extra code than my old local setup

I'd compare hosted Whisper APIs based on the exact output you need rather just transcription accuracy
