A large trade is one Polymarket fill large enough for 0xinsider to record it: 10,000ormoreinUSDCatapriceunder0.97,or10,000 or more in USDC at a price under `0.97`, or 1,000 or more at a price under 0.99 on an Earnings market. Use this route for an alert feed or a live view of what graded wallets are buying right now. For a time window, one market, or one wallet, use Large trades history. For one trade and the wallets on the other side of it, use Large trade.

Parameters

has_more and next_cursor describe the filtered result, so a full page always holds limit matching trades.

Key response fields

Example

What it does not return

  • A trade under min_size, which defaults to 5000. Lowering it does not reach fills below the size at which 0xinsider records a trade at all.
  • A side, condition_id, trader, from, or to filter. Large trades history has the last four.
  • The wallets on the other side of a trade. Open one row with Large trade for its makers.
  • A prediction. review_score reads the fill’s size, its price, the wallet’s win rate, and the trade’s age. It says nothing about how the market will resolve.
  • Proof of insider trading. A high suspicion_score marks a trade for review, which is what Suspicious trades is for.

Caching

Send the ETag from a response back in an If-None-Match header. If the list has not changed, you get 304 Not Modified with an empty body. data_quality is part of the representation and its stored clocks are included in the ETag; meta.cached and meta.cache_age_s describe the transport cache.

Authorizations

Authorization
string
header
required

Legacy default or named integration API key, or OAuth 2.1 access token, in the Authorization header as Bearer oxi_sk_live_... or Bearer oxi_at_.... Default keys retain full access; integration keys are limited to their approved read, webhooks, export and usage scopes and expire within 90 days. All credentials share the owner's account limits. Data calls require an active Pro subscription and return live data. A 401 carries WWW-Authenticate: Bearer resource_metadata="https://api.0xinsider.com/.well-known/oauth-protected-resource" (RFC 6750 section 3, RFC 9728).

Headers

If-None-Match
string

Conditional GET validator from a previous ETag. Matching values return 304 Not Modified with an empty body.

Query Parameters

limit
integer
default:20

Maximum number of recent large trades to return.

Required range: 1 <= x <= 100
cursor
string

Pagination cursor from previous response's next_cursor.

min_size
number
default:5000

Minimum trade size in USD.

category
string

Filter by market category (case-insensitive). A canonical bucket name (e.g. Basketball) matches every provider member that folds into it (NBA, WNBA, NCAAB); a raw provider value also resolves to its bucket.

min_grade
enum<string>

Minimum trader grade.

Available options:
S,
A,
B,
C,
D,
F
suspicious_only
boolean
default:false

When true, return only rows with persisted suspicion_score >= 60. The filter is applied before SQL-backed limit + 1 pagination.

min_market_volume_share
number

Keep only trades whose market_volume_share is known and at least this. A fraction, not a percent: 0.01 is one percent of the market's traded volume. A trade whose share is unavailable is never returned by a non-zero value, because an unavailable share cannot be said to clear a floor.

Required range: 0 <= x <= 1
sort
enum<string>
default:recent

Order of the returned page. recent is newest first and is the default. market_volume_share ranks by each trade's share of its market's traded volume, biggest first, with a trade whose share is unavailable last. That ranking reads the last 30 days, because the share is computed for each request and an unbounded ranking cannot be served inside the documented latency budget. A cursor is bound to the order it was minted in, so a continuation cannot cross from one order into the other.

Available options:
recent,
market_volume_share

Response

required
Allowed value: "list"

next_cursor

total
integer

Total matching rows when the read model exposes a count; absent (or null) when it does not.
