Collection notes
Plans are the five self-serve columns of the pricing table (Free, XS, S, M, L); Enterprise is custom. Monthly prices are the monthly-billed ones; the page now shows the yearly-billed price per month beside them. Credits are entered as characters: text to speech is one credit per character. The price beyond the plan is the rate of the "Additional 100k credits" row (whole dollars on the page of 2026-10-29; before, $6.9 for XS), billed only when usage-based billing is turned on in the account. The Plan Details table marks commercial use by icons the page text does not carry, so it is recorded only for the Free plan, whose terms state it. No MCP server page was found.
