Quickstart Provider docs

Pricing

Managed routing

Speech only: $188 / 1M chars
With timestamps: $188 / 1M chars

Speechbase pays the provider; you spend credits.

BYOK

Platform fee: 3.4%
Speech only: 6.39 cr / 1K chars

Your provider key pays upstream; Speechbase charges the platform fee.

This model returns native word-level timing, so timestamps do not change the managed routing price.
