Welcome!

Welcome to CrazyTel's API documentation. This guide will help you integrate with our telecommunications services programmatically.

What is CrazyTel?

CrazyTel is a comprehensive telecommunications service provider offering scalable solutions for purchasing and managing phone numbers (DIDs) across multiple regions. Our platform enables businesses and developers to programmatically handle their telecommunications needs through a straightforward API interface, with real-time management capabilities and detailed reporting tools.

API

The CrazyTel API currently focuses on two core functionalities:

• Balance Management: Monitor and manage your account balance to ensure uninterrupted service. Track your spending, view transaction history, and set up automated balance alerts to maintain continuous service availability.

• Phone Number (DID) Operations: Search, purchase, configure, and manage phone numbers across our supported regions. Our API enables you to programmatically browse available numbers, complete purchases, modify configurations, and manage your existing number inventory.

Whether you're a new customer or an existing user, our "Getting Started with Crazytel API" section will guide you through the essential steps to integrate with our services. The API Features Overview section details our current capabilities, while the API Reference provides hands-on examples and interactive testing tools for each endpoint.
