Get Daily Snapshot By Date
GET/v1/cryptodata/backtesting/daily-snapshots/{date}
Retrieve an archived daily snapshot for `date` (YYYY-MM-DD UTC). Returns the full snapshot identical in shape to `/api/v1/daily`, including the new `onchain_health_score` field. Use this to build historical regime-tagged backtests without re-computing per-day signals yourself. A snapshot for today is not written until the 20:00 UTC daily build (it is keyed by build date, so day D lands at 20:00 UTC on D — NOT 01:00 UTC, which is the separate backtesting Parquet export). Those 404s carry `Retry-After` (seconds until that build) so a polling client backs off instead of hot- looping; one consumer was observed retrying today's date ~1900 times in 2h.
