Relationships and timelines

Follow the links between records and read a Site's or Project's dated events.

Edges: GET /v1/{collection}/{id}/edges

Filter with label (repeatable) and direction (in, out or both). Page with cursor and limit (up to 200, default 50).

GET /v1/sites/site_4716cb782b285d45a11ba85a64289ba0/edges?label=operates&label=owns
{
  "items": [
    { "label": "operates", "direction": "in",
      "node": { "id": "org_b03e249d1f03599ea9f6c3a37deb43c5", "name": "FIRESTONE POLYMERS, LLC" },
      "properties": { "confidence": 1.0, "method": "hard_key", "role": "operator", "from": "2026-10-05" } },
    { "label": "owns", "direction": "in",
      "node": { "id": "org_b03e249d1f03599ea9f6c3a37deb43c5", "name": "FIRESTONE POLYMERS, LLC" },
      "properties": { "confidence": 1.0, "method": "hard_key" } }
  ],
  "next_cursor": null
}
Edge propertyMeaning
confidence0 to 1, on the same scale as attribute values.
methodhard_key: matched on an exact identifier. rule: set by a fixed Indax rule. splink: a probabilistic match. geo: matched by distance, within 500 m.
fromThe date Indax first saw the link, not the date operation began.

Indax never merges companies on a name alone. If a Site's owner is spelled two ways, both appear as owners. When you group by company, check both the operator and the owners.

Timelines: GET /v1/sites/{id}/timeline

Sites and Projects have timelines, newest first. Filter with since and until (YYYY-MM-DD) and event_type (repeatable). GET /v1/events/{id} returns one event in the same shape.

GET /v1/sites/site_4ed23885f4755785acba58fa0ab0a4db/timeline?since=2020-01-01&event_type=violation&event_type=enforcement
{
  "items": [
    { "id": "evt_043e51101e2a52e0aac7b8055e4f4a78", "event_type": "violation",
      "event_date": "2025-06-12", "date_kind": "occurred", "status": "resolved" },
    { "id": "evt_0c45d8eacc3e5c308d41e947597d1df8", "event_type": "enforcement",
      "event_date": "2024-09-09", "date_kind": "closed", "penalty_current_usd": 200000 }
  ],
  "next_cursor": "eyJ2IjoxLCJvIjozfQ"
}

Each event also has an event_subtype; the full list is in GET /openapi.json. date_kind says which date event_date is, for example issued, occurred or closed. project_forming is true when the event can start or extend a Project.
