Collection notes

Pay as you go only: the Pro plan at the Melia 1 pre-recorded base rate of $0.24 an audio hour. The $0.12 an hour headline of the pricing page applies only with both the model-training discount (-33%) and the top-tier annual commitment discount (-25%), so the base rate is the price recorded. Charges are to the exact second. The real-time (streaming) rate is not stated in the page text, so the streaming plan has no price and is not listed. New sign-ups get a one-time $100 credit. No Speechmatics MCP server is described on the pages read. Authentication is by API key.
