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"

​
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.
