Reliable API source/sports date feed for up to the minute fight updates?

Weird question I know.

Anyone know of a reliable sports API I can poll that will tell me when the first bell goes on a big fight?
I guess I can suck and see but if they are paid access then the pricing could mount up trialling them and I waste time as well.

I know I could get AI to scrape for me but token usage gets quite expensive that way.
