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.
GET /quota/:key returns remaining credits and account review status.
GET /status/:textId returns current delivery status for a send.
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.

Enter an existing API key to refill it, or leave the key blank to create a new one. New keys start in review before live sends are enabled.
