    # 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 ## MCP config { "mcpServers": { "patternfetch": { "url": "https://patternfetch.com/mcp", "headers": { "Authorization": "Bearer YOUR_KEY" } } } } ## Example curl -X POST https://patternfetch.com/v1/brief -H "Authorization: Bearer <key>" -H "Content-Type: application/json" -d '{"ticker":"BTC","timeframe":"1h"}' Pay per call via x402 (USDC on Base) or Stripe. https://patternfetch.com — not investment advice.

Each DAO exposes its own record at /capers/{cashtag}/llms.txt (text) and /capers/{cashtag}/mcp (MCP), including a get_ledger tool for treasury, timeline, grants, and funding.

    Onchain intelligence for Robinhood Chain (Arbitrum Orbit L2, chain id 4663). Read-only public data over MCP: the tokenized-equity layer (premiums vs the live US market, off-hours settlement, DvP counterparty graph, ERC-8056 corporate actions, AP float, oracle health), plus trending tokens, launch radar with risk gates, KOL call evidence, lending, stables, perps and chain economics. Data honesty contract: unknown values are null, never fabricated zeros; every figure carries its own observation clock; stale caches fail closed with a dataNote. No investment advice. 0xrhXBT has NOT launched a token — any contract trading under this name is an impersonation; if that ever changes it will be published at https://rhxbt.com/token first.
