Recorded rate history per market

The hourly series of one or more markets, recorded by the origin from Boros's own candles back to each market's launch (matured markets included): implied (fixed) APR open/high/low/close, mark APR, the venue's underlying funding, Boros's 7- and 30-day funding moving averages, volume and open interest (live hours only). `interval=day` folds to UTC days (implied = the day's last close, funding = the day's mean). Percent APRs. Window: `days` (default 30 hourly / 180 daily, max 400) or `from` / `to` (unix seconds or ISO).

**Parameters**

| Name | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `marketIds` | query | string | yes | CSV of Boros market ids (max 50) |
| `interval` | query | "hour" \| "day" | no | hour (default) or day |
| `days` | query | string | no | Window length in days |
| `from` | query | string | no | Window start, unix seconds or ISO |
| `to` | query | string | no | Window end, unix seconds or ISO |

**Response `200`** — `{ interval, from, to, series: { [marketId]: point[] } }`

| Field | Type | Description |
| --- | --- | --- |
| `success` | true |  |
| `data` | object | Informational payload. `null` when the endpoint only builds calldata. |
| `actions` | null |  |

**Example response**

```json
{
  "success": true,
  "data": {}
}
```

**Response `400`** — Validation error

**Response `429`** — Rate limited. Unauthenticated callers share a per-IP budget; send an `x-api-key` header to lift it. Retry with exponential backoff.

**Response `500`** — Unexpected server error. Safe to retry with backoff.

**Response `502`** — An upstream data source or protocol origin failed (`error.code` is `ORIGIN_FAILED`). `error.details` carries the per-origin status. This is also what a missing or malformed required parameter currently returns, rather than a 400.
