Tools

• closing_soon ~1995 tokens
  Use when the user wants to see markets that will resolve within the next 36 hours. Returns markets sorted by close timestamp ascending. Takes the /markets filters, e.g. `source=` and `categories=` (CSV); price-derivative markets are included unless `hide_price_derivatives=true`.
• get_event ~410 tokens
  Use when an agent needs the full detail of a single prediction-market event by its composite key (source + event_id). Returns the event with all of its child markets, latest probabilities, and metadata. The canonical URL `https://pdata.world/events/{source}/{event_id}` is stable for the lifetime of
• get_event_similar ~184 tokens
  Use when an agent needs events similar to a given event — cross-platform equivalents and topically-related markets, precomputed nightly from title embeddings. Best-first; empty list (never an error) when no similarities are known yet.
• get_market ~202 tokens
  Use when an agent needs the full detail of a single market by its composite key (source + market_id). Returns the market with its parent event reference, current probability, volume, 24h delta, and historical chart points. Includes a `_meta.cite_as` field that the agent can drop directly into its re
• get_summary ~202 tokens
  Use when an agent needs platform-level context before drilling into individual markets: one row per platform (Polymarket, Kalshi, Manifold, Myriad, Limitless, Predict, Opinion, Gemini) carrying 24h notional volume, active event and market counts, and that platform's category mix. Takes no parameters
• list_countries ~2039 tokens
  Use when an agent needs the list of country tags that markets have been tagged with. Returns the canonical country vocabulary with per-country market counts. Accepts the same filter params as `list_markets` (source, category, status, volume/probability ranges, search, …): the counts then reflect tha
• list_events ~1688 tokens
  Use when an agent wants to browse, filter, or search prediction-market events across all 8 platforms. Returns paginated events with their child markets, prices, and platform metadata. Filterable by source (polymarket/kalshi/manifold/myriad/limitless/predict/opinion/gemini), category, country, status
• list_markets ~2057 tokens
  Use when the user wants to browse, filter, or sort individual markets (not events). Returns paginated markets with their probability, volume, source, parent event ID, and 24h delta. Filterable by source, country, category, status, and full-text `search`. Sortable by `volume_24hr` or `probability`. C
• list_news_movers ~949 tokens
  Use when the user wants to see the news-feed view: markets that exhibited a probability spike in the chosen lookback window, scored by `|Δprob_pp| × log10(1+USD-equivalent volume)`. Refreshed after each Polymarket ingest cycle, typically every 15-20 min. The `window=` param selects the lookback: 24
• map_heat ~190 tokens
  Use when you need a geographic snapshot of where prediction-market attention is concentrated. Returns per-country heat (capped news score, summed) for the current moment (`at=now`) or a past hour (`at=<ISO8601>`).
• map_timeline ~109 tokens
  Use when you need the hourly total-heat time series that drives the /map playback scrubber. History accretes from launch (no backfill).
• news_movers_by_category ~591 tokens
  Use when the user wants the news feed bucketed by category. Returns the same data shape as `list_news_movers` but pre-grouped into the canonical 14-category vocabulary, with cluster grouping inside each bucket. Useful for 'what's moving in politics?' style queries.
• search_suggest ~362 tokens
  Use when an agent has a name or phrase and needs the `(source, id)` of the matching event or market before calling another tool. Resolves free text against events AND markets in one call, best-first, and reports `total_events` / `total_markets` so the agent can tell a precise hit from an ambiguous o
• top_movers ~2048 tokens
  Use when the user wants to see markets with the largest 24h probability swings. Returns the top N movers (default 5, max 20) ranked by absolute `prob_24h_change`, among open markets that moved more than 2 points on over 1,000 units of 24h volume, one per event. Takes the /markets filters; Climate an
