Questions

Good to know.

What do I pay for SMS API?
Every Pozy account includes it. You pay per connected account: the first 2 are free, then $6 each for accounts 3 to 10, $3 each for 11 to 100 and $1 each from 101, per month. On top of that: SMS costs from $0.008 per segment by destination. Phone numbers cost from $3 a month each, by country. Every rate is on the pricing page.
Can my AI agent use this?
Yes. Everything here is available through the Pozy MCP server at https://mcp.pozy.ai/mcp, with the permissions you approve when you sign in.
