PnL

Get merged PnL data for a user across one or more wallets/providers

Fetches and merges PnL records/summary across the wallets supplied for this user via the general-purpose PnL path — not the real-time pipeline used by /pnl/hover and /pnl/wallet-totals. At least one of polymarket_wallet, kalshi_wallet, or hyperliquid_wallet is required — the request is rejected with 400 if none are supplied. polymarket_wallet and hyperliquid_wallet must be valid Ethereum addresses (normalized/lower-cased); kalshi_wallet is treated as an opaque user-id string (Kalshi is a CEX with internal, non-address identifiers). provider (repeatable query param, up to 16 items) filters the merged result down to specific provider(s); when omitted, all providers implied by the supplied wallets are used. Kalshi and Hyperliquid PnL are served only through this aggregate endpoint; neither is available from /pnl/hover or /pnl/wallet-totals. Hyperliquid open-position and unrealized PnL use HIP-4 balances and mark prices, while realized PnL and fee fields are currently zero. The caller-supplied {user_id} MUST match the authenticated principal’s own id (JWT sub, or user_id for API-key auth) — mismatches are rejected with 403; this endpoint can only ever return the caller’s own PnL. limit/offset paginate the merged record list; internally up to min(limit + offset, 1000) records per provider are fetched, so total/has_more in the response describe the page relative to that ceiling, not an authoritative full-history count. For API-key callers, each requested provider must additionally have its API access enabled; JWT/admin callers are exempt.
