Quickstart

Your first cross-strategy correlation in three calls — no key required (the API is open today). Base URL: https://btc-strategy-data-api.fly.dev.

:::note Factual data, not advice Every response is backtested / modelled historical data for professional & institutional use. Past performance is not indicative of future results — not advice, not a recommendation, not a forecast. :::

1 · Discover the strategies​

curl https://btc-strategy-data-api.fly.dev/v1/strategies

Every response is the canonical envelope — data, meta, links:

{
  "data": [{ "id": "atg_4h_ema", "label": "4H EMA 50/20/200", "base_risk_pct": 0.025,
             "verification_state": "dual_verified",
             "headline": { "cagr_pct": 50.53, "sharpe_daily_annualized": 1.18 } }],
  "meta": { "basis": "backtested", "dataset_version": "2026-06-24T07:40:35Z", "count": 17 },
  "links": { "self": "/v1/strategies", "summary": "/v1/summary" }
}

2 · Pull the correlation matrix​

curl "https://btc-strategy-data-api.fly.dev/v1/correlation?period=daily"

Pearson correlation of aligned daily returns — risk-invariant (unchanged by risk_pct).
