puts response.read_body

List all available feed events, grouped by feed vertical. Returns event keys, venues, outcome counts, and pre-built channel names.

Parameters

string

default:"all"

Filter by feed vertical: macro, crypto, or weather.

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.

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"

}

Field	Description
`event_key`	Unique identifier for the event. Use this in channel subscriptions.
`event_date`	Calendar date of the release (YYYY-MM-DD).
`release_at`	Full 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.
`venues`	Which 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.
`outcomes`	Number of outcomes (default) OR full outcome array (with `expand=outcomes`).
`enrichment`	External data source attached to every message. Only present for enriched feeds (`"binance"` for crypto). Macro events do not have this field.
`channels.dist`	Event-level — subscribe to this single channel to get the joint cross-venue distribution for all outcomes. Free tier.
`channels.snapshot`	Event-level — full state reset every 60s. Pro tier.
`channels.book` / `channels.trade`	Templates 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.

Example

curl -H "X-API-Key: oddpool_..." "https://api.oddpool.com/feeds/event-types"

      "release_url": "https://www.bls.gov/cpi/",
      "category": "inflation",
      "vertical": "macro"
    },
    "fomc": {
      "label": "FOMC Rate Decision",
      "description": "Federal Open Market Committee policy decision on the federal funds rate target range. Eight scheduled meetings per year.",
      "agency": "Federal Reserve",
      "release_local_time": "14:00",
      "timezone": "America/New_York",

    }
  }
}

Field	Description
`label`	Human-readable name. Use in dashboards.
`description`	One-paragraph plain-English explanation.
`agency`	Who publishes the data.
`release_local_time`	Time-of-day at which releases typically drop, in the named timezone. `null` for continuous markets (crypto).
`timezone`	IANA timezone identifier for `release_local_time`.
`category`	Higher-level grouping (`inflation`, `employment`, `growth`, `monetary_policy`, `markets`, `crypto`, `weather`).
`vertical`	Which `feed=` filter this type belongs to.
