Troubleshooting
Why am I getting no results?
Check your creatorUsername filter. If the username does not exist or has no markets, the Actor returns an empty dataset. Try removing the filter and running again.
Why did my run stop before reaching maxItems?
The Actor stops when it has collected maxItems markets or when there are no more markets matching your filters. Lower maxItems or broaden your filters to collect more.
Why are some fields empty in my dataset?
Some fields, like resolution data, are only present for resolved markets. If you set includeResolved to false, those fields will be empty for active markets.
Can I get markets from a specific date range?
This Actor does not support date filtering directly. You can filter by creator username and resolved status, then sort or filter the exported dataset by date in your own tooling.
