# Graphql

How to access the WoopChain API using GraphQL

GraphQL can reduce the overhead needed for common queries. For example, instead of querying each receipt in a block, GraphQL can get the same result with a single query for the entire block.

The \[Woop GraphQL schema] describes the GraphQL implementation for Ethereum. Enable the GraphQL service using [command line options](https://github.com/Woop-Chain/docs/blob/main/docs/woop/how-to/use-woop-api/index.md#enable-api-access).

!!! note

```
GraphQL is not supported over WebSocket.
```

Access the GraphQL endpoint at `http://<HOST>:<PORT>/graphql`. Configure `<HOST>` and `<PORT>` using [`graphql-http-host`](https://github.com/Woop-Chain/docs/blob/main/docs/woop/reference/cli/options.md#graphql-http-host) and [`graphql-http-port`](https://github.com/Woop-Chain/docs/blob/main/docs/woop/reference/cli/options.md#graphql-http-port). The default endpoint is `http://127.0.0.1:8547/graphql`.

## GraphQL requests with cURL

[WoopChain JSON-RPC API methods](https://github.com/Woop-Chain/docs/blob/main/docs/woop/reference/api/index.md) with an equivalent [GraphQL](/docs/json-rpc-commands/graphql.md) query include a GraphQL request and result in the method example.

!!! example

````
The following [`syncing`](../../reference/api/index.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 to the \[Woop GraphQL schema] from within the app.

## Pending

`transactionCount` and `transactions` supports the Pending query.

!!! important

```
Woop does not execute pending transactions so results from `account`, `call`, and `estimateGas`
for Pending do not reflect pending transactions.
```

!!! example

````
=== "Pending transaction count"

    ```bash
    curl -X POST -H "Content-Type: application/json" --data '{ "query": "{pending {transactionCount}}"}' http://localhost:8547/graphql
    ```

=== "Result"

    ```bash
    {
      "data" : {
        "pending" : {
          "transactionCount" : 2
        }
      }
    }
    ```
````

!!! example

````
=== "Pending transactions"

    ```bash
    curl -X POST -H "Content-Type: application/json" --data '{ "query": "{pending {transactions{hash}}}"}' http://localhost:8547/graphql
    ```

=== "Result"

    ```bash
    {
      "data" : {
        "pending" : {
          "transactions" : [ {
            "hash" : "0xbb3ab8e2113a4afdde9753782cb0680408c0d5b982572dda117a4c72fafbf3fa"
          }, {
            "hash" : "0xf6bd6b1bccf765024bd482a71c6855428e2903895982090ab5dbb0feda717af6"
          } ]
        }
      }
    }
    ```
