Get Claim Signature

The Boost API allows you to get the required signature for claiming boost incentives using the GET /signatures endpoint.

​

Basic Usage

Fetch a signature for claiming a boost:

const params = new URLSearchParams({
  txHash: '0x2dfc8f4f24b1a3a7ee73ea13b8a20a63fe7457d1c96b95178d3ea4126b6bf5ad',
  boostId: '8453:12'
});

const response = await fetch(
  `https://api-v2.boost.xyz/signatures?${params.toString()}`
);
const { signature, claimant, incentiveId } = await response.json();

​

Required Parameters

• txHash: The transaction hash that completed the boost’s required action
• boostId: The ID of the boost (format: chainId:boostNumber)
• claimData: (Optional) Additional data required for variable incentive types

// Example response structure from the API
{
    "signature": "0x...",   // Signature for verification
    "claimant": "0x...",    // Address eligible to claim
    "incentiveId": 0        // ID of the claimable incentive
}

​

Using the Signature

Once you have the signature from the API, you can use it with the following SDK methods to claim your boost:

• BoostCore.claimIncentive - Claim for the transaction sender
• BoostCore.claimIncentiveFor - Claim on behalf of another address
