Comma-separated status list; any of {open, closing-soon, resolved}

Full-text search across title, description, slug. Case-insensitive substring match.

Field name; prefix '-' for descending order (e.g. -volume_24hr). Common allowed values: volume_24hr, normalized_vol_24hr, liquidity, end_date, closed_time, updated_at. Markets endpoints additionally accept probability, prob_24h_change, spread. Invalid values return 400.

Comma-separated category labels to include (OR)

Comma-separated category labels to exclude

If true, exclude events with is_price_derivative=TRUE

If true, the include clause also matches rows whose categories array is empty/NULL or contains only labels outside the canonical set (synthetic 'Other' bucket).

Comma-separated country names to include (OR). Full English names per the AI categorizer's prompt — e.g. 'United States', 'United Kingdom', 'European Union'. No allow-list — misspelled values silently yield zero matches.

How multiple countries combine: 'any' (default, OR — tagged with any selected country) or 'all' (AND — tagged with all of them, e.g. both Iran and Israel). Markets carry ≤3 country tags.
