# What is recorded as connected to this event

`GET /api/v1/events/{eventId}/related`

## Request

- Base URL: `https://offnadir-delta.com`
- URL: `https://offnadir-delta.com/api/v1/events/{eventId}/related`
- Auth: one of:
  - HTTP bearer
  - API key in header `X-API-Key`

1 tokens. Returns only the relations recorded for this event when it was processed — nothing is inferred on request. `related` lists other events, and each carries `shares`: the registry facility both are linked to (`kind: facility`, with how the other event was linked), the place both reports name (`kind: place`, only places resolved to a town or finer), or a stored relation (`kind: relation`, `same_campaign`, with the model probability). `merged_in` lists reports of the same event that were merged into it. `facilities` and `places` give each connector with its total `other_count` beside how many are `listed`, and `accounting.not_listed` counts the rest. Events that are merely close in space and time are not relations and are not returned. A shared location is not a shared cause. Plan-dependent: on a plan without the relations the related events are withheld, and on a plan without the full event detail (Free) the facilities and places too; `plan_lock` says so, with `section_plans` naming the plan that opens each part — an empty list there means not shown, not none.

## Path parameters
