# Get Quant History

`GET /api/v1/quant/history`

## Request

- Base URL: `https://cryptodataapi.com`
- URL: `https://cryptodataapi.com/api/v1/quant/history`
- Auth: API key in header `X-API-Key`

Past probability rows — the verification surface (Pro Plus).

Every row records what the model said at that moment, with `backfilled`
distinguishing live point-in-time inferences (15-minute cadence) from
retro-computed history (1-hour cadence, written by the backfill script)
and `model_version` pinning which artifact produced it. Use this to score
our calls against what actually happened — black-box probabilities are
worthless; auditable ones aren't.

## Query parameters

- `scope` string: 'market' or a coin symbol, e.g. BTC
- `start` string, required: ISO 8601 or unix ms
- `end` string, nullable
- `horizon` '4h' | '24h', nullable
- `limit` integer
- `format` 'json' | 'csv'
