On 15 Nov 2026 TheRundown included a WebSocket from Ultra ($399), ParlayAPI from Business ($40), SharpAPI as a $99 to $149 add-on, Odds-API.io as an add-on equal to the plan price, and SportsGameOdds on its custom All-Star plan. novigapi.com streams Novig changes on every plan, live from $49.

A stream saves credits and latency when you watch many markets. Check how a provider counts a connection and whether the free tier gets a delayed feed.

## Where novigapi.com falls short

> Our stream follows Novig's public data, so changes arrive 5 to 30 seconds after they happen, and it carries Novig only.

## Try it

```python
import asyncio, json, os, websockets

async def main():
    url = "wss://stream.novigapi.com/v1/stream?key=" + os.environ["NOVIGAPI_KEY"]
    async with websockets.connect(url) as ws:
        await ws.send(json.dumps({"op": "subscribe", "league": "NBA", "types": ["price.changed", "line.move"]}))
        async for msg in ws:
            print(json.loads(msg))

asyncio.run(main())
```

## Questions

### Is a WebSocket faster than polling?

Usually, and cheaper: you get each change once instead of asking repeatedly. Our stream costs 2 credits per 285 seconds a connection stays open.
