Approval before sending
Every account starts in review so traffic stays consent-based and carrier friendly.
SMS credits, API keys, and compliance gates
Business texting without the carrier paperwork maze.
Text King gives small teams the Textedly-style business texting experience with a simple API underneath. Buy credits, get reviewed, and send consent-based messages through our Twilio or Telnyx delivery layer.

API under the hood
Textbelt-style simplicity with paid credits, quota checks, and delivery callbacks.
Textbelt-simple API
The first production surface is intentionally small: send a single SMS, spend credits, track delivery, and respect opt-outs.
POST /v1/messages sends one consent-based SMS.
Authorization uses a Bearer API key, or a key form field for simple clients.
One credit is one SMS segment; long messages spend multiple credits.
Replies containing STOP, QUIT, END, CANCEL, UNSUBSCRIBE, OPT OUT, or REVOKE block future sends.
Prepaid launch pricing
Checkout creates a pending API key. We review the use case before enabling live sends.
