Book-level summary + cross-strategy correlation.

📄️Book-level summary

Gauge the diversification of the whole set in one call — mean pairwise correlation and effective bets (how many independent bets the 14 behave like). Preview returns the snapshot; the equal-weight book performance (what holding them together would have done) is full-tier.

📄️Cross-strategy correlation matrix

See how independent the strategies are from each other before you blend — the raw material for diversification. Pearson correlation of aligned periodic returns; risk-invariant. Optional `ids` subset. Free — no key required.

📄️Aligned returns matrix + correlation (json|csv)

Pull every strategy's aligned return series as one matrix — drop it straight into your own optimiser or correlation analysis against your book. Plus the correlation matrix; `risk_pct` modelled-rescales returns per strategy (correlation unchanged). CSV is a raw table (not enveloped). **Free — no key required.**
