Troubleshooting
Why am I getting no results?
Your 'Filter by market name' may be too specific. Try a shorter substring or leave it empty to retrieve all markets.
Why is the run slow?
If you set a very high 'Maximum markets', the actor may take longer. Reduce the limit or narrow your filter.
Why are some markets missing?
PredictIt may have removed or renamed markets. Check the website directly to confirm availability.
Can I get historical data?
This actor only returns current listings. For historical data, you would need to run it periodically and store snapshots.
Why did the run fail?
Check the actor log for errors. It could be a temporary website issue; retry after a few minutes.
