# GraphQL over HTTP
|
||
|
|
||
|
GraphQL can reduce the overhead needed for common queries. For example, instead of querying each receipt in a
|
||
|
block, GraphQL can obtain the same result with a single query for the entire block.
|
||
|
|
||
|
## GraphQL Requests with Curl
|
||
|
|
||
|
[Pantheon JSON-RPC API methods](../Reference/Pantheon-API-Methods.md) with an equivalent [GraphQL](../Pantheon-API/GraphQL.md)
|
||
|
query include a GraphQL request and result in the method example.
|
||
|
|
||
|
!!! example
|
||
|
The following [`syncing`](../Reference/Pantheon-API-Methods.md#eth_syncing) request returns data about the synchronization status.
|
||
|
```bash
|
||
|
curl -X POST -H "Content-Type: application/json" --data '{ "query": "{syncing{startingBlock currentBlock highestBlock}}"}' http://localhost:8547/graphql
|
||
|
```
|
||
|
|
||
|
## GraphQL Requests with GraphiQL App
|
||
|
|
||
|
The third-party tool [GraphiQL](https://github.com/skevy/graphiql-app) provides a tabbed interface for editing and testing GraphQL
|
||
|
queries and mutations. GraphiQL also provides access the Pantheon GraphQL schema from within the app.
