novigapi.com tags fast, one-direction Novig moves as steam and serves them from /line-moves?kind=steam, or pushes them by signed webhook on Production and Scale. Between 12 and 15 Nov 2026 it tagged 38,938 steam moves among 844,413 recorded line moves (read 15 Nov 2026). (Source: [novigapi.com pricing](https://novigapi.com/pricing))

On an exchange, steam is someone taking every resting bid at several prices in a short window. It shows up in the book before it shows up in a daily close.

## How the options compare

## Where novigapi.com falls short

> Our move detection runs on snapshots a few seconds apart, so a move that reverses inside one snapshot is not recorded. Tick-level detection needs the official WebSocket.

## Try it

```bash
curl -s "https://novigapi.com/api/v1/line-moves?kind=steam&since=2026-11-15T00:00:00Z&limit=50" \
  -H "Authorization: Bearer $NOVIGAPI_KEY"

## Questions

### Is steam the same as sharp money?

Often, but not always: steam is a fast move; it can also come from news. Check volume and open interest alongside it.
