Nine dedicated endpoints cover every layer of the exchange's public market data: events, tradeable Yes/No contracts, order-book depth, OHLC price history, and trade feeds. ## What's available The [Kalshi endpoint family](https://anysite.io/endpoints/kalshi/) spans three categories: - **Events** — retrieve a prediction-market event by ticker or search events within a series. An event groups the tradeable contracts for a specific question and date window. - **Markets** — five endpoints covering individual Yes/No contracts: current prices and open interest, OHLC candlestick history (1m, 1h, or 1d), order-book snapshots with depth, market search by event or series, and the public trade feed with taker side and block trade flags. - **Series** — retrieve and search the template records that define recurring contract programmes (category, frequency, fee structure, and settlement sources). ## Why it matters Kalshi's contracts are real-money signals on what markets believe will happen — not survey data, not social sentiment. A contract trading at 70 cents on the Yes side means market participants collectively assign 70% probability to that outcome. That kind of calibrated, financially-committed probability signal is useful in ways traditional data sources aren't: grounding LLM forecasting pipelines, tracking political risk in real time, or building dashboards that surface implied probabilities alongside conventional price data. Because Kalshi is CFTC-regulated, its data is auditable and methodologically consistent — a meaningful difference for researchers and quantitative applications that need to defend their inputs. ## Getting started All Kalshi endpoints follow the same access pattern as the rest of the Anysite API — a single `access-token` header. No Kalshi account, no exchange credentials, no OAuth flow. ``` curl -X POST "https://api.anysite.io/api/kalshi/markets/search" \ -H "access-token: YOUR_TOKEN" \ -H "Content-Type: application/json" \ -d '{"series_ticker": "KXBTCD", "status": "open", "count": 20}' ``` The same endpoints are available as MCP tools in Claude Desktop, Cursor, and ChatGPT via the Anysite MCP server. Full documentation, parameter reference, and example workflows are on the [Kalshi endpoint page](https://anysite.io/endpoints/kalshi/).
