Crypto ETF Sentinel — Week-over-week pipeline delta for US spot crypto ETFs: change in stage counts, filings-7d and under-review count vs a prior daily snapshot (days_back, default 7, max 90). Use when you want the net movement of the crypto ETF pipeline since your last check rather than a full snapshot. Returns 404 (no charge) when no snapshot exists.
