API reference

Versioned REST over the ownership graph.

The surface below is the shape of the API. Full request and response schemas publish with the API itself, so this page can never describe an endpoint that does not exist.

Authentication

Tokens are scoped to a tenant and carry the same object-level permissions as the user or service that issued them.

Idempotency

Write requests accept an idempotency key. A retried create returns the original record rather than a duplicate.

Versioning

Breaking changes arrive as /v2. The current version keeps working until it is formally deprecated with notice.

The object model behind these endpoints is described under Developers.

Build the ownership record before somebody asks for it.

Register what exists, connect the relationships, attach the evidence. The answer you need under deadline is the one you maintained beforehand.
