# Introduction

> DeFi Orbit is on-chain data infrastructure for DeFi positions — a multi-chain data API built for funds, market makers, and the teams building on DeFi.

DeFi Orbit sits between raw chain data and your product: position state is read from protocol contracts, indexed in-house, and served as clean, calculated data. Access liquidity positions, lending markets, fees, APR, and protocol analytics across supported blockchains through a single REST API. Use one API key to retrieve on-chain DeFi data and monitor API usage across your organization. The API is one of three ways to use the same data layer, alongside the [Portfolio app](https://app.defiorbit.xyz) and [DeFi Orbit AI](/recipes/mcp), the MCP server for AI agents.

> Send your `do_sk_` key as a bearer token on every request.

> **[Protocols](/protocols)**

## Base URL

https://api.defiorbit.xyz
```

Authenticate every API request using your API key in the header:

`Authorization: Bearer YOUR_API_KEY`

API requests consume credits from your organization's allocated balance. Credit costs vary by endpoint.
Create and revoke API keys from the [Dashboard](https://platform.defiorbit.xyz/dashboard/keys).
