Haha totally get this. We wanted to give info about how we bill (ie, per second and we don't charge for customization) but we haven't publicly disclosed our rate yet. It's pretty low (fraction of a cent per second).
I'm sure you're aware of this, but for those who aren't, your YC buddy scaleapi.com offers human transcription for a fraction of a cent per second as well.
With scaleAPI, you also have a 1 day delay in getting your response.
Yup! Scale has a good API for human transcription. We're an order of magnitude cheaper than human transcription services though.
