# Aragon Agreements Subgraph Introduction

Aragon Agreements has a GraphQL API Endpoint hosted by [The Graph](https://thegraph.com/docs/about/introduction#what-the-graph-is) called a subgraph for indexing and organizing data from the Aragon Agreements smart contracts.

Subgraph information is serviced by a decentralized group of server operators called Indexers.
