GET/v1/model/events

Read the model transaction event feed

operation ID: get_v1_model_events

Overview

Read the model transaction event feed. The model API describes assets, attributes, bindings, templates, views, registries, and governed changes that give series data its operational meaning.

When to use it

  • Use it when an application needs to read the model transaction event feed.
  • Use it when a modeling tool is building, governing, resolving, or inspecting the asset and attribute hierarchy.

Quick example

Set the base URL and replace generated identifiers or credentials with values from your installation.

cURL

curl --request GET \
  --url "$ORDINATE_URL/v1/model/events" \
  --header "Authorization: Bearer $ORDINATE_TOKEN"

Expected output · 200

Transactions in ascending order with nested events

Example 200 output

[
  {
    "tx_id": 0,
    "committed_ns": 0,
    "principal": "string",
    "reason": "string",
    "events": [
      {
        "entity_kind": "string",
        "entity_id": "00000000-0000-4000-8000-000000000001",
        "action": "string",
        "details": {}
      }
    ]
  }
]

The cURL request supplies the documented path and query values and asks OrdinateDB to read the model transaction event feed. The documented 200 response is transactions in ascending order with nested events.

How it works

Assets form the composition hierarchy, attributes describe values on those assets, and time-bounded bindings connect attributes to stored series.
