patternfetch

One API/MCP call turns a crypto ticker + timeframe into a token-compact market-state brief — so an LLM trading agent never has to dump raw OHLCV into its context.

Instead of hundreds of raw candles you get: compact candles + a SAX shape signature, detected chart/candlestick patterns (double top/bottom, head & shoulders, engulfing, hammer, doji), support/resistance clusters, a regime label, and interpreted indicators (RSI / EMA / ATR) + a one-line summary. Crypto-first. Impersonal and non-directive — data, never buy/sell advice.

Endpoints

  • POST /v1/brief ($0.01) — full market-state brief
  • POST /v1/delta ($0.008, $0.001 if unchanged) — only what changed since your last brief
  • POST /v1/candles ($0.005) — compact candle codec only
  • POST /v1/analogs ($0.05) — historical outcome distribution (n, win-rate, median, min, max)
  • POST /v1/keys (free) — self-serve API key + $0.05 credit

Raw names from tools/list. Only developers need these.

patternfetch_briefGet 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.
patternfetch_deltaGet 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.
patternfetch_analogsFind 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.
