# Introduction

> Unified API for cross-chain swaps, bridges, and fiat on-ramp across 90+ blockchains

# Welcome to Hypermid

Hypermid is a **unified Partner API** that gives you access to cross-chain swaps, token bridges, and fiat on-ramp functionality through a single integration. Instead of building separate integrations with multiple bridge protocols, DEX aggregators, and payment providers, Hypermid handles the complexity so you can ship faster.

Use the REST API directly or one of the official SDKs in **TypeScript, Python, Go, or Rust**. The **anonymous tier works out of the box** — no API key required to start. An API key is only needed if you're a partner with negotiated terms (custom fee splits, higher rate limits, scoped webhooks).

## How It Works

Hypermid acts as a **server-side proxy** between your application and upstream providers. Your users never interact with bridge or DEX providers directly — all traffic flows through the Hypermid API.

```
Your App  →  Hypermid API  →  Bridge & DEX Providers
                ↕
         Partner Dashboard
```

This architecture provides several benefits:

* **Single integration** — one API key, one response format, one set of error codes
* **Rate limiting and caching** — Hypermid manages upstream rate limits so you don't have to
* **Fee management** — configure your fee tier once in the dashboard
* **Analytics** — all transactions are tracked and available via the Partner API
