Openapi messaging & communications

All services use a Bearer token (see the openapi-auth skill). Every send is an outward-facing, paid action: always confirm recipient, content and cost with the user before sending.

SMS v2 — https://sms.openapi.com

• POST /IT-messages (Italy), POST /ES-messages (Spain), POST /WW-messages (worldwide)
• POST /otp — OTP verification messages
• GET /messages, GET /messages/{id} — sent messages and delivery status

Features: custom sender, E.164 validation, GSM-7/UCS-2 detection with automatic segmentation, dry_run for free testing, webhook delivery callbacks. Messages expire after 48h (status EXPIRED). Worldwide pricing is computed post-sending and requires a minimum credit balance. SMS v1 (ws.messaggisms.com) is deprecated.
