Indexer API

If you do not want to index the chain yourself, the indexer behind Bull Launch answers GraphQL over HTTP, and a WebSocket per token for live market and discussion updates. It is the same API the app uses.

Every paged response carries a checkpoint { blockNumber timestamp }. Check it before trusting a figure: it tells you how far behind the chain the answer is, and it is the fastest way to tell an indexer that is merely lagging from one following the wrong chain.

// The newest launches, the same query the home page runs
const r = await fetch("https://api.bulllaunch.fun/graphql", {
  method: "POST",
  headers: { "content-type": "application/json" },
  body: JSON.stringify({
    query: `query { discoverLaunches(order: NEW, first: 5) {
      nodes {
        token { address symbol image description }
        market { poolId baseAsset { symbol } }
        bondingProgressBps
      }
      checkpoint { blockNumber timestamp }
      endCursor hasNextPage
    } }`,
  }),
});
