# Introduction

> ePhone AI is a unified AI model aggregation platform that gives you access to OpenAI, Anthropic, Google, and dozens of other leading providers through a single API.

## What is ePhone AI

ePhone AI is an AI model aggregation service built for developers and businesses.

With a single API endpoint and one API key, you can access the latest models from OpenAI, Anthropic, Google, DeepSeek, and more — without registering on multiple platforms, juggling multiple keys, or managing separate wallets. The platform is fully compatible with both the OpenAI and Anthropic **dual-protocol** standards, so switching from a direct provider integration requires minimal code changes.

## Key Features

### One-Stop Model Aggregation

Create one API key and use one unified API standard to call models from any supported provider. No more managing multiple accounts, keys, or billing wallets.

* **Unified identity**: One API key controls access to all providers
* **Unified billing**: Transparent usage tracking and cost control in a single account
* **Rich model selection**: Access the latest models from OpenAI, Anthropic, Google, DeepSeek, and more

### Native Dual-Protocol Support

Fully compatible with both the OpenAI and Anthropic protocol standards — integrates seamlessly with Claude Code, Cursor, Cline, and other popular development tools. Choose whichever protocol fits your stack without worrying about provider differences.

* **OpenAI compatible**: Call all platform models through the OpenAI standard API
* **Anthropic compatible**: Call all platform models through the Anthropic standard API — perfect for Claude Code and similar tools

### High Capacity & High Availability

We maintain ample capacity for every major model to ensure your business is not constrained by any single provider's limits.

* **Multi-provider support**: Key models are backed by multiple provider nodes
* **Automatic failover**: When a provider has issues, requests are seamlessly rerouted to other available nodes — no interruptions
* **High concurrency**: Enterprise-grade concurrency capacity for large-scale products

### Intelligent Routing

The system automatically selects the best available node based on your token configuration. Supports sorting by **latency, price, or throughput**, and allows per-request routing overrides via headers — fully transparent to your code.

### Global Edge Nodes

Powered by **Cloudflare Enterprise** infrastructure, the platform deploys distributed edge nodes worldwide. Wherever your users are, requests are routed to the nearest node, significantly reducing network latency and improving response speed.

* **Global coverage**: Edge nodes across all major regions worldwide
* **Low-latency access**: Local entry points reduce cross-region transmission delay
* **Highly available**: Multi-node redundancy ensures stable service

### Observability

Deep, multi-dimensional visibility into your AI model usage — quickly identify issues, optimize costs, and improve outcomes.

* **Detailed call logs**: Complete records of every API request and response
* **Usage analytics**: Real-time monitoring of token consumption and call frequency
* **Cost analysis**: Analyze cost distribution by model and time period
* **Performance monitoring**: Track response time, availability, and other key metrics

### Flexible Pricing

Pay only for what you use. No minimums. Supports token-based, per-request, and per-second billing — scales elastically with your business.
