| ------------ | ------------------------------------------------------------------------------------------------- |
| `recurrence` | Filter by recurrence: `daily`, `weekly`, or `monthly`.                                            |
| `active`     | Filter by active status. Defaults to active-only; pass `active=false` to include inactive series. |
| `limit`      | 1–200 (default 50).                                                                               |
| `offset`     | Offset for pagination (default 0).                                                                |

<Tip>The crypto up/down feature is just a named series. Fetch its current events with [Get Series Detail](/api-reference/discovery/series-detail) — e.g. `/series/btc-up-or-down-daily`.</Tip>
