Get a token-compact market-state brief for a crypto ticker + timeframe. Returns compact candles, detected chart/candlestick patterns with geometric confidence, support/resistance levels, trend/regime, and interpreted indicators (RSI/EMA state) plus a one-line summary. WHEN: an agent needs the current technical picture of a market without dumping raw OHLCV into context (saves tokens, avoids numeric hallucination). WHEN NOT: you need order execution, portfolio advice, or non-crypto assets. Example: {"ticker":"BTC/USDT","timeframe":"4h"}. Output is impersonal market data, NOT investment advice.

Get only what CHANGED since your last brief for a ticker+timeframe (trend flips, new patterns, RSI-state changes). WHEN: an agent polls the same market repeatedly and wants minimal tokens. Returns changed=false when nothing material changed. Impersonal data, not advice.

Find historical windows whose shape resembles the current price action and return the FULL distribution of what followed (win-rate, median, min, max, n) over a fixed forward horizon. WHEN: an agent wants historical context for a setup. NOT a prediction, NOT a backtest of a strategy; past distribution does not guarantee future results. Impersonal data, not advice.

List supported assets, timeframes, endpoints, and limits for patternfetch.
