List Opinion markets with filtering and sorting. Returns tradeable markets only (standalone binaries + categorical outcomes). Categorical parent markets are excluded.
ConstraintValue
limit1–100 (default 20)

​
Event Grouping

  • event_id, event_slug, and event_title come from the parent market for categorical outcomes. These are null for standalone binaries.
  • Opinion calls these “parent markets” natively — Predexon normalizes to “event” for cross-venue consistency.

​
Notes

  • collection is non-null for recurring markets (e.g. hourly crypto). Contains title, symbol, and frequency.
  • price in outcomes is null when the indexer hasn’t populated prices yet.
