The /v1/ endpoints are the versioned interface to the same real-estate data. Base URL: https://api.trassets.ai. Send your API key in the X-API-Key header on every request. All responses are JSON. Every /v1/ response is a top-level JSON array — there is no wrapping envelope. See Response Structure for the object, array, and code/label patterns the tables follow.

​
Endpoint types

Raw endpoints are unversioned: they expose source tables below the modelled layer, so there is no /v1/ variant.

​
Response headers

Category endpoints return pagination metadata in headers, not in the body:
  • X-Total-Count — total rows matching the query
  • X-Has-More — "true" or "false"
  • X-Next-Offset — the offset for the next page
  • X-Next-Cursor — an opaque cursor when a full page is returned, on the endpoints that support cursor pagination; absent where the table has no cursor column, see Pagination

​
Error format

Errors follow RFC 7807 (application/problem+json). Every error object contains type, title, status, detail, and instance. See Errors for a full list of status codes and retry guidance.

​
Versioning

Tables are migrated to /v1/ one at a time, alongside the unversioned base path — both work today, with no redirect and no confirmed sunset date for unversioned paths yet. See Versioning for the current rollout state.

Endpoint groups

Property

Property objects, structure tree, technical objects, and creditor service assignments — see the Property group in the sidebar.

Operations

Notifications and projects — see the Operations group in the sidebar.

Stakeholder

Creditors, employees, owners, and tenants — see the Stakeholder group in the sidebar.
Not every unversioned table has a /v1/ counterpart yet — kontenmapping_ranges, offers, and orders are still base-path only. Data Model Overview lists what /v1/ covers today.

​
Unversioned endpoints

Four endpoint groups exist once for the whole API and carry no /v1/ prefix. They are listed in the sidebar below the categories.
