# Get whale trade by ID

`GET /api/v1/whale-trades/{id}`

Returns one whale trade by raw whale_alerts.id or the wt_-prefixed id emitted by list and history responses.

## Path parameters

- `id` string, required

## Headers

- `If-None-Match` string

## Response `200`

Whale trade

- object
  - `object` 'whale_trade', required
  - `data` WhaleTrade, required
    - `id` string, required — Prefixed ID (wt_...).
    - `traded_at` string, date-time, required
    - `size_usd` number, required
    - `side` 'BUY' | 'SELL', required
    - `outcome` string, nullable — Traded outcome label (e.g. "Yes"/"No"/team name), resolved provider-first from the trade's outcome_index against market_canonical (index 0 -> yes, 1 -> no). Distinct axis from side (BUY/SELL): side is the trade direction, outcome is which leg was traded. null for multi-outcome (outcome_index >= 2) or unsynced markets; a Kalshi row carries its provider label here (only token_id is null for Kalshi, since there is no CLOB token).
    - `token_id` string, nullable — The Polymarket CLOB token id (ERC1155 asset id, decimal string) for the traded outcome; null when unavailable (e.g. Kalshi markets, unsynced markets).
    - `price` number, required
    - `signal_score` number, required — 0.0–1.0 normalized signal score.
    - `trader` object, required
      - `id` string, required
      - `address` string, required
      - `username` string, nullable
      - `grade` string, nullable
    - `market` object, required
      - `id` string, required
      - `condition_id` string, required
      - `title` string, required
      - `slug` string, nullable
      - `category` string, nullable — Provider-backed market_canonical category.
  - `meta` ResponseMeta, required
    - `request_id` string, required — Unique request ID (req_ prefix).
    - `cached` boolean, required
    - `cache_age_s` integer, nullable — Cache age in seconds, null if not cached.
