The skill directs coding assistants to place synthetic voice calls using endpoints at https://stablephone.dev. Every paid action runs via npx agentcash@latest fetch using x402 transactions. You provide prompt instructions up to 4000 characters, select a voice profile like josh or nat, and set call durations.
Dialing is strictly limited to North American +1 numbers in E.164 format. If a recipient is registered on a Do-Not-Call list, the endpoint responds with HTTP 403 and must not be retried. Outbound calls run at $0.54 each, while a dedicated caller ID line costs $20.00 for a 30-day term.
An async lookup tool checks if a target phone supports iMessage or FaceTime for $0.05. Status updates stream back through a polling token. Without an active agentcash wallet setup, all payment-gated requests fail immediately.
What it helps with
- dispatch outbound AI voice calls using custom prompts
- purchase dedicated US or Canadian phone numbers
- retrieve full text transcripts and call audio recordings
- drop automated voicemails when recipients do not pick up
- check whether a target contact supports iMessage or FaceTime
