Building VirtualSMS — SMS verification for AI agents
Hey IH 👋 Building VirtualSMS — SMS verification API with real SIM-backed numbers (not VoIP), built-in MCP server for AI agents, x402 stablecoin payments. Bootstrapped, remote-first. Today shipped to ~9 backlink directories in one focused session. Excited to share more learnings here as we go.

Derrick — "found nothing, built it" is the best validation story. Real SIMs vs VoIP is a clear technical moat that actually matters to buyers.
At $2.5K/mo you've proven the demand. The next question is whether your landing page and signup flow converts at the rate the product deserves — API tools like this often lose developers at the docs or pricing page before they ever try it.
I run conversion audits for founders — find exactly where that drop-off happens. Happy to take a look.
