# Welcome to HyperFlowSI

> The AI marketplace of the HyperFlow ecosystem, on Elysium. One OpenAI-compatible API key for models from many labs.

**HyperFlowSI** is the AI marketplace of the HyperFlow ecosystem, running on Elysium mainnet, an L2 on HyperEVM. It gives you one API key for models from many AI labs: OpenAI, Google, Anthropic, xAI, DeepSeek, Qwen, Mistral and more. It speaks the OpenAI API, so the client you already use works by changing its base URL. Every request is paid at the model's list price from one credit balance, funded with USDC on Elysium, at [super.hyperflow.fun](https://super.hyperflow.fun).

HyperFlowSI is part of one ecosystem for trading and AI across the Hyperliquid chains. Trading lives at [hyperflow.fun](https://hyperflow.fun); see [Ecosystem](/ecosystem/overview) for everything HyperFlow builds.

#### [Models](/models/overview)

Every model in one catalog, grouped by lab, priced in the unit it's sold by.

#### [Integrations](/integrations/overview)

The OpenAI SDK, the Vercel AI SDK, LangChain, PydanticAI and more.

#### [Coding Agents](/coding-agents/overview)

Use HyperFlowSI models in Cursor, Cline, Continue, OpenCode, Aider and other agents.

#### [API Reference](/api/overview)

Every endpoint, parameter and error.

#### [Marketplace](/marketplace/overview)

How the marketplace works today, and the open marketplace coming next.

## Why HyperFlowSI

* **One key, many labs.** Call any model in the catalog with the same key and the same code. Switching models means changing one field. See [Models](/models/overview).
* **List price, no subscription.** Every model is charged at its list price, and you pay only for what you use. See [Pricing](/models/pricing).
* **Keys you control.** Give each key a name, the models it may call and a spending limit, and watch usage and every request in the console. See [Account](/account).
