How much do your agents save by paying for services per call?
Two questions. For every service, we compare the vendor’s subscription with paying per call — with that vendor or an equivalent provider — and keep the cheaper one.
Which agent do you build?

Free plan: two wallets for three months, no commitment and no credit card.
If you subscribe instead of paying per call6 of these 8 services require a minimum plan, due every month even if you use nothing. Per call: $0.$270 / month
