description: >-
Ocean subgraph is an off-chain service which provides information about
datatokens, users, balances using the GraphQL. Ocean subgraph provides a
faster way to fetch data rather than on-chain query.
---
# Using Ocean Subgraph
For each supported network, an individual Ocean subgraph is deployed. The information about supported networks and the subgraph URL is available on [this page](../../core-concepts/networks.md).
