### **Overview**

The DAS API indexes all mints and token accounts for the Solana Token Program and Token Extensions Program. It allows querying token balances, metadata, and associated program details.

#### **Supported Queries**

* **GetAsset**: Fetch details of a specific token mint.
* **GetAssetsByOwner**: Retrieve all tokens (fungible and non-fungible) held by an account.
* **SearchAssets**: Search for assets using filters, including token type.

#### **Querying Token Balances**

DAS API supports querying token balances across:

* SPL Tokens
* Token22 Tokens
* NFTs (regular and compressed NFTs)

The DAS API supports Token22 tokens and their extensions. The response includes the `mint_extensions` field when applicable.

**Example Token22 Response**

```json
{
    "mint_extensions": {
        "transfer_fee_config": {
            "withheld_amount": 0,
            "newer_transfer_fee": {
                "epoch": 500,
                "maximum_fee": 1000000000,
                "transfer_fee_basis_points": 500
            },
            "withdraw_withheld_authority": "AuthorityPublicKey",
            "transfer_fee_config_authority": "AuthorityPublicKey"
        }
    }
}
```

### **Conclusion**

The DAS API allows querying of fungible tokens, SPL and Token22, including metadata, balances, and associated program details.
