Feed catalog
curl --request GET \
  --url https://api.oddpool.com/feeds/catalog
List all available feed events, grouped by feed vertical. Returns event keys, venues, outcome counts, and pre-built channel names.

​
Parameters

​
feed
string
default:"all"
Filter by feed vertical: macro, crypto, or weather.
​
status
string
default:"all"
Filter by event status: active, upcoming, or resolved. Useful for crypto feeds where hundreds of short-lived events accumulate — use status=active to get only live events.
​
expand
string
default:""
Opt-in expansions, comma-separated. Supported values:
  • channels — adds a ready-to-paste subscribe_all array to each event listing every channel you’d subscribe to.
  • outcomes — replaces the integer outcomes count with the full outcome list (same shape as the single-event endpoint).
  • * — all expansions.
The default response stays compact for browsing; agents subscribing to data should use expand=channels to skip the second API call.

​
Example

# All active crypto events
curl -H "X-API-Key: oddpool_..." \
  "https://api.oddpool.com/feeds/catalog?feed=crypto&status=active"

# Macro events with ready-to-paste subscribe arrays
curl -H "X-API-Key: oddpool_..." \
  "https://api.oddpool.com/feeds/catalog?feed=macro&expand=channels"

FieldDescription
event_keyUnique identifier for the event. Use this in channel subscriptions.
event_dateCalendar date of the release (YYYY-MM-DD).
release_atFull ISO 8601 timestamp with timezone for the actual release moment. CPI is 8:30 ET (12:30 UTC), FOMC is 14:00 ET, etc. Use this for scheduling and timing logic.
venuesWhich prediction market venues have outcomes configured for this event. Caveat: this reflects “configured” not “currently quoting”. An event listing both venues may have one quiet venue with no live book.
outcomesNumber of outcomes (default) OR full outcome array (with expand=outcomes).
enrichmentExternal data source attached to every message. Only present for enriched feeds ("binance" for crypto). Macro events do not have this field.
channels.distEvent-level — subscribe to this single channel to get the joint cross-venue distribution for all outcomes. Free tier.
channels.snapshotEvent-level — full state reset every 60s. Pro tier.
channels.book / channels.tradeTemplates with {outcome_key} placeholder. Per-outcome channels — replace the placeholder with a value from expand=outcomes or the single-event endpoint. Pro tier.

​
Response with ?expand=channels

Adds subscribe_all to each event — a ready-to-paste array of every channel for that event: 
{
  "event_key": "fomc-2026-06-17",
  "channels": {
    "dist": "dist:fomc-2026-06-17",
    "snapshot": "snapshot:fomc-2026-06-17",
    "book": "book:fomc-2026-06-17:{outcome_key}",
    "trade": "trade:fomc-2026-06-17:{outcome_key}",
    "subscribe_all": [
      "dist:fomc-2026-06-17",
      "snapshot:fomc-2026-06-17",
      "book:fomc-2026-06-17:cut_50",
      "book:fomc-2026-06-17:cut_25",
      "book:fomc-2026-06-17:hold",
      "book:fomc-2026-06-17:hike_25",
      "book:fomc-2026-06-17:hike_50",
      "trade:fomc-2026-06-17:cut_50",
      "trade:fomc-2026-06-17:cut_25",
      "trade:fomc-2026-06-17:hold",
      "trade:fomc-2026-06-17:hike_25",
      "trade:fomc-2026-06-17:hike_50"
    ]
  }
}
Use subscribe_all directly as the channels field of your WebSocket subscribe action. No more N+1 lookup for outcome keys.

​
Response with ?expand=outcomes

Replaces the integer outcomes count with the full outcome array (same shape as the single-event endpoint): 
{
  "event_key": "fomc-2026-06-17",
  "outcome_count": 5,
  "outcomes": [
    {
      "outcome_key": "hold",
      "label": "Fed maintains rate",
      "venues": ["kalshi", "polymarket"],
      "channels": {
        "book": "book:fomc-2026-06-17:hold",
        "trade": "trade:fomc-2026-06-17:hold"
      }
    },
    "..."
  ]
}
When expand=outcomes is set, both outcomes (array) and outcome_count (number) are returned. Without expand, only outcomes (number) is returned.

Decode event types

GET https://api.oddpool.com/feeds/event-types
Returns a stable dictionary mapping each event_type token (e.g., cpi, fomc, nfp) to human-readable label, description, publishing agency, typical release time + timezone, source URL, and category. Use this to interpret event_type values without prior macro-economic knowledge.
