# List Fixed Rate Exchanges
|
|
|
|
The result of following GraphQL query returns the information about the Fixed Rate Exchanges.  
|
|
|
|
{% hint style="info" %}
|
|
Copy the query in the [graphiQL interface](https://v4.subgraph.mainnet.oceanprotocol.com/subgraphs/name/oceanprotocol/ocean-subgraph/graphql) to fetch the results from the mainnet. For other networks, change the domain name with appropriate subgraph domain as mentioned in [this page](../../core-concepts/networks.md).
