# List large positions

`GET /api/v1/large-positions`

Returns the largest current open positions from graded traders, value-descending, with opaque cursor pagination. Polymarket-only by design: the large-positions scanner filters platform = 'polymarket' (backend/src/large_positions/scanner.rs:238,245), so no Kalshi rows are ever scanned and a Kalshi or unknown condition_id filter returns an empty list (never fabricated rows). The teaser cap that the internal product UI applies to anonymous viewers does not apply here: the API key already proves an active insider/annual subscription, so authed API callers get full access.

## Query parameters

- `limit` integer
- `cursor` string
- `min_size` number
- `category` string
- `min_grade` 'S' | 'A' | 'B' | 'C' | 'D' | 'F'
- `condition_id` string

## Response `200`

Large positions list

- object
  - `object` 'list', required
  - `data` LargePosition[], required
    - `id` string, required — Composite prefixed ID `pos_<wallet>:<condition_id>:<outcome_index>`.
    - `platform` 'polymarket' | 'kalshi', required — Provider discriminator. Always polymarket today (scanner is Polymarket-only); kept in the shape so Kalshi can land without a breaking change.
    - `total_size_usd` number, nullable — Aggregate provider currentValue for this position leg in USD.
    - `position_unrealized_pnl` number, nullable — Provider per-position unrealized P&L (trader_markets.unrealized_pnl_num, from Polymarket cashPnl).
    - `share_count` number, required — Live share count for this position.
    - `avg_entry_price` number, nullable — Volume-weighted entry price.
    - `current_price` number, nullable — Latest provider mark price for the position's token.
    - `outcome_label` string, nullable — Backend-resolved outcome label (provider outcome, else Yes/No from the binary index).

    - `event_leg_count` integer, required — Legs collapsed into this representative row for one (wallet, event, outcome side) group. 1 means standalone.
    - `event_total_value_usd` number, nullable — Aggregate provider currentValue across collapsed sibling legs; equals total_size_usd when event_leg_count = 1.
    - `first_seen_at` string, date-time, required
    - `last_updated_at` string, date-time, required
    - `trader` object, required
      - `id` string, required — Prefixed ID (`trd_...`).

      - `markets_traded` integer, nullable
    - `market` object, required

      - `slug` string, nullable
      - `event_slug` string, nullable
      - `category` string, nullable
  - `has_more` boolean, required
  - `next_cursor` string, nullable — Opaque cursor for the next page; absent on the last page.
  - `total` integer, nullable — Total ranked rows when the read model exposes a count; may be absent.
  - `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.

## Other responses

- `304` — Not Modified. Returned when If-None-Match matches the current payload.

- `401` — Missing or invalid API key
- `402` — Active Insider subscription required
- `403` — Account access denied
