Historical Data

By default, all RotoWire news and feed endpoints return data for the current day. Using the hours or date parameters, you can look back up to 2 weeks of historical data. Access beyond 2 weeks requires a custom arrangement — contact your RotoWire sales representative for details.

How It Works

RotoWire feed endpoints (News, Injuries, Updates, etc.) support two parameters for retrieving historical data:

Parameter	Format	Example
hours	Integer	&hours=48
date	MMDDYYYY	&date=05102026

hours Parameter

Use hours to look back a set number of hours from now. You can set hours to any value, but data will always cut off at 2 weeks regardless of how large the number is.

Example: https://api.rotowire.com/Baseball/MLB/News.php?key={key}&format=json&hours=48

Setting hours=8760 will still only return the last 2 weeks of data.

date Parameter

Use date to retrieve data from a specific calendar day using the format MMDDYYYY. Requesting a date older than 2 weeks will return data from the 2-week cutoff — it does not return an error.

Example: https://api.rotowire.com/Baseball/MLB/News.php?key={key}&format=json&date=05102026

Requesting an old date like date=01012026 silently clamps to the 2-week limit.

The 2-Week Limit

Scenario	Result
hours=48	Returns last 48 hours
hours=336	Returns last 2 weeks (336 hrs = 14 days)
hours=8760	Capped at 2 weeks
date=05102026 (within 2 weeks)	Returns that days data
date=01012026 (older than 2 weeks)	Returns data from the 2-week cutoff

Extended Historical Access

If your use case requires data older than 2 weeks, RotoWire offers extended historical access as a custom arrangement. Contact your RotoWire sales representative to discuss options.
