  • # 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.

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.

  • RelayLaunch helps local service businesses get found in AI-assisted search, get booked, and keep the customers they already have, in that order. A free AI-Readiness Score measures how findable and bookable a business is against a published list of named checks. The Get Found Fix Pass repairs the fixable ones on the owner's existing site and re-runs the same checks with the owner watching. Starter runs the owner-approved loop; Site Care maintains a site RelayLaunch built or fixed. Every action is owner-approved before it reaches a customer.
