PnL

Live per-market PnL for a (wallet, market) pair

Live “hover” PnL for a single wallet on a single market, sourced from a fast real-time pipeline — quick regardless of how far back the wallet’s earliest trade goes. Returns one row per token held on the contract (e.g. YES + NO for a binary market) plus aggregate totals across those tokens. Only providers on this pipeline are supported: polymarket, opinion, predictfun; kalshi and hyperliquid are rejected with 400 and must use /pnl/{user_id}. When the underlying pipeline is disabled (e.g. while a backfill is ramping), the endpoint returns a well-formed zero/empty payload (tokens: [], all totals 0.0) instead of erroring, matching the “no data” state the frontend already renders gracefully. For API-key callers, the requested provider must additionally have its API access enabled.
