GET
Use this endpoint for a feed of recorded large trades. 0xinsider records fills of at least 10,000belowprice‘0.97‘,oratleast10,000 below price `0.97`, or at least 1,000 below 0.99 in Earnings markets. To filter by time range, market, or wallet, use Large trades history. To inspect one trade’s counterparties, 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

​
Poll for new trades

Poll with since and If-None-Match instead of downloading the whole list each time:
  1. Call the route once without since. Keep the ETag header and the first trade’s id.
  2. Call it again with since set to that id and If-None-Match set to that ETag. When no trade was recorded since, the server returns 304 Not Modified with no body.
  3. When trades come back, handle them, keep the new ETag, and move since to the first trade of that response. If has_more is true, read the rest with cursor and the same since before you move it.
since follows the order trades were recorded in, not traded_at. A trade recorded late, with an earlier traded_at, still comes back, and a trade that is still being written comes back on a later poll instead of being skipped. A late trade can come back twice, so deduplicate on id.

​
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

Save the response’s ETag and send it in If-None-Match on your next request. If the list has not changed, the server returns 304 Not Modified with no body. With since, a poll that finds no new trade gets that 304, because an empty answer does not change between polls. 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. Out-of-range values are clamped to 1..100.

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
​
since
string

Return only the trades recorded after this one. Pass the id of a large trade this API returned (wt_, or the bare integer). The answer keeps the list shape and newest-first order, and next_cursor pages within it. After means commit order: a trade recorded late with an earlier traded_at is still returned, and a trade whose write has not committed yet is returned on a later poll, never skipped. To poll, send the id of the first trade on the first page of your last answer that had trades, with If-None-Match set to the ETag you last received; when nothing new was recorded the answer is 304 with an empty body. A late trade can come back once, so deduplicate on id. Only with sort=recent. An id that names no trade, or one more than 10000 trades behind the newest, answers 400 with error.param since; request the list without since and continue from its first trade.
