Failed calls are never charged. ## What is actually differentiated here Most market data is a repackaged public feed and we do not pretend otherwise. These four are not obtainable elsewhere, because they are the live outputs of a real algorithmic trading system rather than a vendor passthrough: - /api/backtest — computation over data, with honest validation: next-open fills (no look-ahead), slippage charged, train/test halves scored separately, buy&hold and SPY baselines always printed, disagreeing halves reported as noise. - /api/regime-forecast — an ML volatility-regime model that actually trades. - /api/track-record — that model's accuracy, scored server-side against realized SPY moves under a rule disclosed in the payload. Predictions are recorded before outcomes. Audit us before you spend anything. - /api/dip-radar — the live dip scan over the exact universe the system trades. ## Honesty policy Staleness is always reported, never hidden. A product whose upstream feed goes stale is withdrawn from sale (HTTP 503) rather than sold at full price — see /api/feed-status for what is currently degraded. ## OpenAI-compatible LLM endpoint Base URL: https://orchard-data.letom1176.workers.dev/v1 (also https://orchard-data.letom1176.workers.dev/api).
