Updated: 2026-11-15

novigapi.com sends signed webhooks when a Novig line moves more than your threshold, on steam, when a market opens and when it settles, on Production ($149) and Scale. On 15 Nov 2026 it had logged 844,413 Novig line moves since 12 Nov 2026, 38,938 of them steam, all readable from /line-moves. (Source: [novigapi.com pricing](https://novigapi.com/pricing))

Polling for moves wastes credits; a webhook calls you when something happens. Each delivery is signed so your endpoint can reject forgeries.

If you only want to look back, /line-moves filters by league, market, kind (move or steam) and minimum size in percentage points.

## Where novigapi.com falls short

> Webhooks start at $149 a month. On Developer you can watch moves over the stream instead, and Free can read /line-moves for the last 7 days.

## Questions

### What counts as a steam move?

A fast move in the same direction across a market within a short window. novigapi.com tags these kind=steam.

### Can I test a webhook before it fires?

Yes: POST /api/v1/webhooks/{id}/test sends a signed sample delivery.
