# Get per-event price history

`GET /api/v1/market-data/prices/event-history`

## Request

- Base URL: `https://rest.ft.42.space`
- URL: `https://rest.ft.42.space/api/v1/market-data/prices/event-history`
- Auth: none declared
- TypeScript: <https://skmtc.dev/42/apis/fortytwo-read-api/docs/api/v1/market-data/prices/event-history/get.ts> (a function with typed inputs; its response is checked against the schema)

Returns one row per onchain event that touched the outcome (mint/redeem/etc), from the outcome_stats hypertable. Unlike /prices/history this is NOT bucketed or gap-filled — each point reflects the marginal price and collateral immediately after a specific event, so the chart can plot per-trade resolution for short windows. Use `start_ts`/`end_ts` to bound the window (required for `start_ts` since the hypertable can be large); use `fidelity` to downsample if the window contains more events than you want to render. Events before the outcome's first real trade are omitted — the market "seed" mint carries a distorted bootstrap price (not a real traded price), and that price is carried forward until the outcome is first traded, so the series opens on a genuine price.
