Contractor AI setup #5: an after-hours phone agent for a remodeling shop, built on @cartesia Managed Agents, which launched yesterday. ... Cost as listed today: $0.03 a minute, plus $0.014 a minute on a Cartesia number. The free plan includes $1 of agent minutes a month, about 33 minutes. Honest limit: it's built for enterprise teams. The commercial use license starts on the Pro plan ($5 a month), the AI model is billed separately (free for a limited time right now), and booking into your calendar needs webhooks, which is developer work.
