REST API vs MCP Server
This page is for the REST API — used for direct HTTP integrations in your apps. If you're connecting an AI agent (Claude, GPT, etc.), use the MCP Server instead — it uses separate API keys.
API Setup
Our REST API allows you to retrieve SMS for your rented numbers in real-time. Available to customers with active 6-month or 12-month rentals.
