# Sui GraphQL

> Sui GraphQL API is available on [Web3 API platform](https://crypto-chief.com/rpc/sui/).

*Sui GraphQL RPC* provides a flexible, schema-driven query interface for Sui blockchain data. Unlike JSON-RPC — which requires one call per resource type — GraphQL lets you request exactly the fields you need across objects, transactions, balances, and checkpoints in a single round trip. The schema supports filtering, cursor-based pagination, and deeply nested lookups, making it ideal for frontends, dashboards, and analytics tooling.

### Endpoint

| Network | Endpoint                                          |
| ------- | ------------------------------------------------- |
| Mainnet | `https://rpc.crypto-chief.com/sui/{YOUR_API_KEY}` |

For Premium users, append your token to the URL: `https://rpc.crypto-chief.com/sui/{YOUR_API_KEY}/{YOUR_API_KEY}`

### Request example

Query the latest checkpoint:

```
curl -X POST https://rpc.crypto-chief.com/sui/{YOUR_API_KEY} \
-H 'Content-Type: application/json' \
-d '{
  "query": "{ checkpoint { sequenceNumber digest timestamp } }"
}'
```

### Response example

```
{
  "data": {
    "checkpoint": {
      "sequenceNumber": 214225619,
      "digest": "GNSviTUX6DXkiCPKYDo1uihJsm5oRcjtvrkT8mVQyay8",
      "timestamp": "2025-03-24T12:00:00Z"
    }
  }
}
```

***

### Query examples

#### Get object by ID

```
curl -X POST https://rpc.crypto-chief.com/sui/{YOUR_API_KEY} \
-H 'Content-Type: application/json' \
-d '{
  "query": "{ object(address: \"0x5\") { address version digest owner { __typename } } }"
}'
```

#### Get address balances

```
curl -X POST https://rpc.crypto-chief.com/sui/{YOUR_API_KEY} \
-H 'Content-Type: application/json' \
-d '{
  "query": "{ address(address: \"0xYOUR_ADDRESS\") { balance { totalBalance coinType { repr } } } }"
}'
```

***

### Key features

* **Composable queries** — request multiple related resources in a single call.
* **Pagination** — default 50 items per page, up to 200 for multi-get operations.
* **Filtering** — narrow results by type, owner, checkpoint range, and more.
* **No overfetching** — get only the fields you need.
