Editorial interest 78/100 Selection signal · not a rating of the site

A developer-focused SMS service for sending access codes, delivery updates, reminders, reservations, and other messages to Brazilian numbers.

Landing page captured for the 2026-09-12 issue.

Field notes

The service models each message as one or more SMS segments and accepts a destination number, text, and API key. Developers can call it through HTTP, TypeScript, Python, cURL, or an MCP tool named `sms_send`, with examples covering authentication, delivery, appointments, reservations, and boarding notices. The visible pricing calculator limits the service to Brazil, quotes values in reais, and notes that long texts and emojis can consume additional credits.
