# Using Ocean Subgraph
|
|
|
|
Ocean subgraph is an off-chain service that provides information about datatokens, users, and balances using GraphQL. The Ocean subgraph provides a faster way to fetch data rather than an on-chain query. The data from Ocean subgraph can be queried using [GraphQL](https://graphql.org/learn/).
|
|
|
|
You can use the Subgraph instances hosted by Ocean Protocol or host your instance. The page on Deploying Ocean Subgraph provides a guide on hosting your own Ocean Subgraph instance.
|
|
|
|
For each supported network, an individual Ocean subgraph is deployed. The information about supported networks are available on this [page](../../core-concepts/networks.md).

#### Ocean Subgraph GraphiQL
|
|
|
|
The below table provides the link to GraphiQL for the support networks. The Graphql queries can be directly executed using the GraphiQL interface without the need of any setup.
