The Boost API allows you to fetch and filter boosts through the GET /boosts endpoint.

​
Basic Usage

Fetch all boosts with no filters: 
const response = await fetch(
  'https://api-v2.boost.xyz/boosts'
);
const { boosts } = await response.json();
For complete API details including all available parameters and response fields, see the API Reference.

​
Filtering Boosts

The owner represents the address that initiated the boost deployment through a budget account.
You can filter boosts using various parameters:
  • chainId: Filter by specific blockchain network
  • owner: Filter by the address that deployed the boost
  • budgetAccount: Filter by specific budget account
Example using multiple filters: 
const params = new URLSearchParams({
  owner: '0x1234...',
  chainId: '8453', // Base
  budgetAccount: '0x5678...'
});

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

​
Pagination

The maximum page size is 100 items.
The endpoint uses simple pagination through page and pageSize parameters. Here’s how to fetch all boosts: 
async function fetchAllBoosts() {
  const pageSize = 20;  // Adjust based on your needs (max 100)
  let currentPage = 1;
  let allBoosts = [];
  
  while (true) {
    const params = new URLSearchParams({
      page: currentPage.toString(),
      pageSize: pageSize.toString()
    });

    const response = await fetch(
      `https://api-v2.boost.xyz/boosts?${params.toString()}`
    );
    
    const { boosts } = await response.json();
    
    // When the API returns an empty boosts array, we've fetched all boosts
    if (!boosts || boosts.length === 0) {
      break;
    }
    
    allBoosts = [...allBoosts, ...boosts];
    currentPage++;
  }

  return allBoosts;
}
