Large Positions

List large positions

Changed on

Returns the largest current open positions from graded traders, value-descending, with opaque cursor pagination. This is a change-detection feed, not a holder list: a row needs a current value of at least 50,000 USD and a live detection in the last 24 hours, so a wallet that holds a market without moving is not listed. For every graded holder of one market use GET /api/v1/market/{condition_id}/holders. Polymarket-only by design: the large-positions scanner filters platform = 'polymarket' (backend/crates/large-positions/src/scanner.rs), so only Polymarket rows are scanned and an 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 Pro subscription (wire tier insider), so authed API callers get full access.

Request

Query parameters

limitinteger

Maximum number of large positions to return.

cursorstring

Opaque pagination cursor from a previous response.

min_sizenumber

Minimum position value in USD. Raises the feed's own floor of 50,000 USD; a smaller value does not lower it.

categorystring

One RFC 4180 CSV record of exact current provider-backed market_canonical.category values. Legacy unquoted lists such as NBA,WNBA remain valid; values containing commas, quotes, or newlines are CSV-quoted. Matching is case-insensitive. Malformed quoted input fails closed as one unknown exact category.

min_grade'S' | 'A' | 'B' | 'C' | 'D' | 'F'

Minimum trader grade.

condition_idstring

Scope to one market. Accepts the raw provider condition_id or the mkt_-prefixed market id (round-trips a value from a list response). Polymarket-only; an unknown id returns [].

Headers

X-Query-Validation'strict'

Opt into strict query-name validation. The default is compatible: unknown names are ignored and reported in X-Query-Ignored. With strict, an unknown name returns 400 bad_request with error.reason unknown_query_parameter before the handler runs, including when its percent escape is incomplete.

Response

Large positions list

object'list' required
has_moreboolean required
next_cursorstring

Opaque cursor for the next page; absent on the last page.

totalinteger

Total ranked rows when the read model exposes a count; may be absent.
