It resolves nothing: a superseded claim and the one that superseded it both appear. Time: as\_of keeps statements begun by that instant of the world and as\_known keeps what this plane had heard by then; either absent is no bound. ## Request 6 fields. | Field | In | Type | Required | Description | | ---------- | ----- | ------- | -------- | -------------------------------------------------------------------------------------------------- | | `entity` | query | string | — | Entity narrows to what was asserted ABOUT one entity. | | `relation` | query | string | — | Relation narrows to one relation. | | `value` | query | string | — | Value narrows to assertions pointing AT one value, which is how the edges into an entity are read. | | `as_of` | query | string | — | AsOf bounds the read to statements begun by an instant of the world, RFC 3339. | | `as_known` | query | string | — | AsKnown bounds the read to what this plane had heard by an instant, RFC 3339. | | `limit` | query | integer | — | Limit caps how many assertions come back. | ## Response | Status | Body | Meaning | | --------- | ------------------ | ------- | | `200` | graph.graphReadOut | ok | | `default` | problem-details | refused | `200` body — 15 fields. | Field | In | Type | Always | Description | | ------------------------- | ---- | ----------------- | ------ | ------------------------------------------------------------------------------------------------------------------------------------------------- | | `assertions` | body | graph.wireFact\[] | — | Assertions are the matching rows: a read's in the order they were written, oldest first; a search's best match first. | | `assertions[].at` | body | string | — | At is when the thing was so, RFC 3339, as the asserter gave it. | | `assertions[].by` | body | string | — | By is the identity that filed it — `owner` or `owner/user` — stamped from the validated principal at the write, never from the body. | | `assertions[].confidence` | body | number (double) | — | Confidence in \[0,1] as the asserter gave it; absent is 0. | | `assertions[].entity` | body | string | — | Entity is the thing described, in the organization's own namespace. | | `assertions[].evidence` | body | string | — | Evidence points at the record the claim came from. | | `assertions[].id` | body | string | — | ID is the assertion's content address, minted by the server from what was asserted. | | `assertions[].knowable` | body | string | — | Knowable is the first instant this plane could have answered with the assertion, RFC 3339: the later of Seen and the server's clock at the write. | | `assertions[].names` | body | boolean | — | Names true means the assertion is an edge and Value is an entity. | | `assertions[].relation` | body | string | — | Relation is what was asserted of it. | | `assertions[].seen` | body | string | — | Seen is when the asserter says it became knowable, RFC 3339. | | `assertions[].source` | body | string | — | Source names who asserted, as the caller gave it. | | `assertions[].until` | body | string | — | Until is when the thing stopped being so, RFC 3339, as the asserter gave it. | | `assertions[].value` | body | string | — | Value is what the relation points at: another entity's key when Names is true, otherwise a scalar. | | `truncated` | body | boolean | — | Truncated says more assertions matched than came back: the limit, or the ceiling, stopped the read. | Failure carries the platform error shape — see [Errors](https://docs.hanzo.ai/docs/errors). ## Examples **CLI** ```bash hanzo graph get ``` **SDK** **.ts** ```ts import { Configuration, GraphApi } from 'hanzoai';
