Realtime stream (SSE)

A Server-Sent Events endpoint that pushes feed snapshots in near-real-time over a single open connection — the efficient alternative to tight polling.

GET/api/feed/stream

Query parameters

Param	Type	Description
`type`	string	Feed to stream: trending (default), top, gainers, or new.
`chain`	string	Restrict to one chain id, or omit for all chains.

Protocol

Content-Type is text/event-stream. Each message is a data: frame whose payload is the same JSON array returned by /api/feed. The first frame arrives on connect, followed by fresh snapshots as the data updates.

event stream

data: [{"chainId":"solana","baseToken":{"symbol":"BOUNTYHOUSE"}, ...}]

Browser (EventSource)

javascript

const es = new EventSource(
  "https://dexscanner.io/api/feed/stream?type=trending"
);

es.onmessage = (e) => {
  const pairs = JSON.parse(e.data);
  render(pairs);
};

es.onerror = () => {
  // EventSource auto-reconnects; close it when you're done:
  // es.close();
};

Node / curl

curl

curl -N "https://dexscanner.io/api/feed/stream?type=trending"

The connection stays open. The server cleans up the interval when the client disconnects.

Versioning

The API is currently unversioned and may change; see the changelog for breaking changes.
