GET /v1/wallets/:addr

One call, every number you need to render a wallet card: lifetime volume, fills, realized PnL, fees paid, open positions, open orders, unrealized estimate, and first/last trade timestamps.

Endpoint

GET /v1/wallets/:addr

The :addr is a 0x-prefixed 40-char hex Ethereum address. Case-insensitive — the response always returns it lowercased.

Field	Description
`lifetime.realized_pnl`	Sum of intraday-close PnL — does NOT include settlement payouts
`lifetime.net_realized_pnl`	`realized_pnl - all fees paid`
`current.unrealized_pnl_estimate`	`Σ amount × (current_mid − avg_cost)` over open positions. Mark-to-mid, not bid/ask
`outcomes_traded`	Count of distinct outcome_ids ever filled
`volume_usdh`	Lifetime gross USDH traded (bought + sold)

Response (wallet not found)

{
  "user": "0x0000000000000000000000000000000000000001",
  "found": false,
  "note": "no fills indexed for this wallet on HIP-4 markets"
}

We return HTTP 200 with found: false rather than 404, so you can distinguish “wallet hasn’t traded HIP-4” from “address syntactically invalid”.

Use cases

Profile cards — top-of-page summary on a wallet detail view.
Quick filtering — “show me only wallets with > 100 fills” before paginating into trades.
Active vs cold wallets — last_trade.relative immediately tells you whether the wallet is still trading.

Examples

curl -H "X-API-Key: hip4_live_..." \
  https://hip4.polynode.dev/api/v1/wallets/0x14bb5440db38aa9f4eb3f11f9c12965ea6c342aa

import requests
addr = "0x14bb5440db38aa9f4eb3f11f9c12965ea6c342aa"
r = requests.get(f"https://.../api/v1/wallets/{addr}",
                 headers={"X-API-Key": key}).json()
print(f"{r['lifetime']['fills_count']} fills, "
      f"{r['lifetime']['volume_usdh']} USDH lifetime, "
      f"{r['current']['unrealized_pnl_estimate']} unrealized")

Notes

All *_pnl fields are returned as decimal strings to avoid float rounding — parse with a decimal lib if you sum them.
realized_pnl reflects the wavg cost-basis algorithm on intraday closes only. After resolution, see settlement_realized_pnl per-position.
