In this guide, you’ll learn how to claim fees for a specific token using the Bags TypeScript SDK with Node.js. The simplified claim flow only requires a token mint address and your wallet — the API handles the rest.

​
Prerequisites

Before starting, make sure you have:

​
1. Set Up Environment Variables

This guide requires your wallet’s private key. Add it to your base .env file: 
# .env
BAGS_API_KEY=your_api_key_here
SOLANA_RPC_URL=https://api.mainnet-beta.solana.com
PRIVATE_KEY=your_base58_encoded_private_key_here  # Required for this guide
You can export your private key from wallets like Bags, Phantom, or Backpack.

​
2. The Fee Claiming Script

Here is a script to claim fees for a specific token. You can save this as claim-fees.ts. The claim flow is straightforward — pass your wallet and the token mint to the SDK and you’ll receive ready-to-sign transactions back.

​
Endpoints Used Under the Hood

This guide uses these API endpoints via the SDK: 
// claim-fees.ts
import dotenv from "dotenv";
dotenv.config({ quiet: true });

import { BagsSDK, signAndSendTransaction } from "@bagsfm/bags-sdk";
import { Keypair, Connection, PublicKey } from "@solana/web3.js";
import bs58 from "bs58";

// Initialize SDK
const BAGS_API_KEY = process.env.BAGS_API_KEY;
const SOLANA_RPC_URL = process.env.SOLANA_RPC_URL;
const PRIVATE_KEY = process.env.PRIVATE_KEY;

if (!BAGS_API_KEY || !SOLANA_RPC_URL || !PRIVATE_KEY) {
    throw new Error("BAGS_API_KEY, SOLANA_RPC_URL, and PRIVATE_KEY are required");
}

const connection = new Connection(SOLANA_RPC_URL);
const sdk = new BagsSDK(BAGS_API_KEY, connection, "processed");

async function claimFeesForToken(tokenMint: string) {
    try {
        if (!PRIVATE_KEY) {
            throw new Error("PRIVATE_KEY is not set");
        }

        const keypair = Keypair.fromSecretKey(bs58.decode(PRIVATE_KEY));
        const commitment = sdk.state.getCommitment();

        console.log(`Claiming fees for token ${tokenMint} with wallet ${keypair.publicKey.toBase58()}`);

        // Get claim transactions — just pass your wallet and token mint
        const claimTransactions = await sdk.fee.getClaimTransactions(
            keypair.publicKey,
            new PublicKey(tokenMint)
        );

        if (!claimTransactions || claimTransactions.length === 0) {
            console.log("No claimable fees found for this token.");
            return;
        }

        console.log(`Generated ${claimTransactions.length} claim transaction(s)`);

        // Sign and send each transaction
        for (let i = 0; i < claimTransactions.length; i++) {
            const transaction = claimTransactions[i];

            try {
                const signature = await signAndSendTransaction(
                    connection,
                    commitment,
                    transaction,
                    keypair
                );
                console.log(`Transaction ${i + 1} confirmed: ${signature}`);
            } catch (txError) {
                console.error(`Failed to send transaction ${i + 1}:`, txError);
            }
        }

        console.log("Fee claiming completed!");
    } catch (error) {
        console.error("Unexpected error:", error);
    }
}

claimFeesForToken("TOKEN_MINT");

3. How It Works

The SDK’s getClaimTransactions() method handles all the complexity for you:
  1. You provide: Your wallet and the token mint
  2. The API automatically: Looks up your claimable position, determines the position type (virtual pool, DAMM V2, custom fee vault), and builds the appropriate claim transactions
  3. You receive: An array of versioned transactions ready to sign and send

​
4. Checking Claimable Positions (Optional)

If you want to inspect your claimable positions before claiming — for example, to check claimable amounts or see which tokens have fees available — you can use the SDK’s getAllClaimablePositions() method: 
async function getClaimablePositions(wallet: PublicKey) {
    const positions = await sdk.fee.getAllClaimablePositions(wallet);

    console.log(`Found ${positions.length} claimable position(s)`);

    for (const position of positions) {
        console.log(`\nToken: ${position.baseMint}`);
        console.log(`  Total claimable: ${(position.totalClaimableLamportsUserShare / 1_000_000_000).toFixed(9)} SOL`);
        console.log(`  Custom fee vault: ${position.isCustomFeeVault ? "Yes" : "No"}`);
    }

    return positions;
}
This is useful for building UIs that display fee balances, or for deciding which tokens to claim fees for.

​
Alternative: Using the Bags CLI

This section requires the Bags CLI. See Install and Set Up the Bags CLI to get started.
The CLI lets you view and claim fees without writing scripts: List all claimable positions: 
bags fees list
Claim fees for a specific token: 
bags fees claim TOKEN_MINT_ADDRESS
Claim all available fees across every token: 
bags fees claim-all
Add --skip-confirm to either claim command to bypass the confirmation prompt (useful for automation).

​
5. Running the Script

Replace TOKEN_MINT with the token mint address you want to claim fees for, then run: 
npx ts-node claim-fees.ts
The script will automatically generate and send claim transactions for the specified token using your wallet.

​
6. Error Handling

Common errors you may encounter:
  • No claimable fees: The wallet has no fees to claim for the specified token
  • Invalid token mint: The token mint address is not a valid Solana public key
  • Insufficient SOL: Your wallet needs SOL for transaction fees
  • Rate limiting: Respect API rate limits between requests
Check the console output for detailed error messages.
