Use cases

Activity feeds — render the most recent trades.
Backfill — page through historical trades by setting to=<earliest you have> and re-querying.
Volume reconstruction — sum notional_usdh across all fills in a window.
Whale detection — filter rows where notional_usdh > 1000.

Examples

# Last 10 trades on outcome 0
curl -H "X-API-Key: hip4_live_..." \
  "https://hip4.polynode.dev/api/v1/markets/0/trades?limit=10"

# All trades since a specific timestamp
curl -H "X-API-Key: hip4_live_..." \
  "https://hip4.polynode.dev/api/v1/markets/0/trades?from=1777740000000000&limit=500"

import requests
# Page through last 24h
import time
ago_24h_us = (int(time.time()) - 86400) * 1_000_000
all_trades = []
to = None
while True:
    params = {'limit': 1000, 'from': ago_24h_us}
    if to: params['to'] = to
    r = requests.get('https://.../api/v1/markets/0/trades',
                     headers={'X-API-Key': key}, params=params).json()
    if not r['trades']: break
    all_trades += r['trades']
    to = r['trades'][-1]['at']['us'] - 1
print(f"24h trades: {len(all_trades)}")

Notes

Sorted reverse-chronological (newest first).
notional_usdh is computed as px × sz server-side.
closed_pnl is HL’s per-fill realized PnL field — it’s only set when the fill closes a position.
Edge-cached for 1 second.
