REST endpoints that serve the same data as a websocket channel link to that channel's page. # 2026.09.21 - Added a new websocket channel [`stock_screener`](https://api.unusualwhales.com/docs/websocket/stock-screener). It streams the latest stock screener row of every ticker and is the live counterpart of [`/screener/stocks`](https://api.unusualwhales.com/docs/operations/PublicApi.ScreenerController.stock_screener). # 2026.09.12 - Added a new websocket channel [`ta_1d_live:{TICKER}`](https://api.unusualwhales.com/docs/websocket/technical-analysis-indicators). The channel streams technical-analysis indicator values (moving averages, RSI, MACD, Bollinger bands, ADX, Aroon, ATR, CCI, MFI, OBV, stochastics and Williams %R) computed on daily candles for one ticker. During regular trading hours it resends the day that is still forming as the price moves, so the newest message for a `date` replaces the ones before it. An indicator reads as `null` until enough daily history exists to compute it. The `1d` in the name is the candle interval and `live` means the values track the open session. # 2026.09.04 - Added new websocket channels [`quotes` and `quotes:{TICKER}`](https://api.unusualwhales.com/docs/websocket/stock-quotes). They stream the live best bid and ask - for every ticker at once, or for a single ticker - and are the live counterpart of [`/stock/:ticker/quote`](https://api.unusualwhales.com/docs/operations/PublicApi.StockQuoteController.show). # 2026.09.01 - Added a global [`greeks`](https://api.unusualwhales.com/docs/websocket/greeks) websocket channel. It streams the same per-contract option greeks as `greeks:`, but for every underlying at once. This is a high volume firehose - prefer the per-ticker channel unless you need the full tape. # 2026.08.30 - MCP now advertises build guidance: `instructions` on initialize; builder prompts `build_dashboard_app`, `build_confluence_alert`, `build_trading_bot`, `build_data_stream`, `start_from_example`, and `setup_api_project`; tools `get_build_recipe` and `get_api_examples` (scripts from [https://github.com/unusual-whales/api-examples](https://github.com/unusual-whales/api-examples)); and `resources/list` / `resources/templates/list` / `resources/read` for playbooks and example files. # 2026.08.28 - Added a new websocket channel [`risk_reversal_skew`](https://api.unusualwhales.com/docs/websocket/risk-reversal-skew). The channel streams live 25- and 10-delta risk reversal skew (put implied volatility minus call implied volatility) per expiry across every ticker, the live counterpart of [`/stock/:ticker/historical-risk-reversal-skew`](https://api.unusualwhales.com/docs/operations/PublicApi.TickerController.historical_risk_reversal_skew). The channel is global only; there is no per-ticker variant. # 2026.08.22 - Updated [`/stock/:ticker/gex-levels`](https://api.unusualwhales.com/docs/operations/PublicApi.TickerController.gex_levels) to derive its levels from directionalized volume instead of a cumulative total over the static open-interest snapshot. - Added `date`, `time`, `source`, and `nearby_flips` to the [`/stock/:ticker/gex-levels`](https://api.unusualwhales.com/docs/operations/PublicApi.TickerController.gex_levels) response. `nearby_flips` lists the five zero-gamma crossings nearest spot, ordered by distance from it. `time` is when the underlying exposure snapshot was calculated. # 2026.08.21 - Added new websocket channels [`interpolated_iv` and `interpolated_iv:TICKER`](https://api.unusualwhales.com/docs/websocket/interpolated-iv). The channels stream interpolated implied volatility and expected moves at fixed horizons (1-365 trading days), the live counterpart of [`/stock/:ticker/interpolated-iv`](https://api.unusualwhales.com/docs/operations/PublicApi.TickerController.interpolated_iv). - Added new websocket channels [`iv_term_structure` and `iv_term_structure:TICKER`](https://api.unusualwhales.com/docs/websocket/iv-term-structure). The channels stream ATM implied volatility and expected moves per real option expiry — the raw entries behind `interpolated_iv` — the live counterpart of [`/stock/:ticker/volatility/term-structure`](https://api.unusualwhales.com/docs/operations/PublicApi.TickerController.implied_volatility_term_structure). # 2026.04.30 Added a new advanced-tier endpoint group.

Unlike a 401 this response carries no `WWW-Authenticate` header, because presenting different credentials for the same token does not change the outcome. Only `code` and `message` are guaranteed.
