Every row is a run that actually happened. ## Request 2 fields. | Field | In | Type | Required | Description | | ------- | ----- | ------- | -------- | ------------------------------------------------------------------- | | `ref` | path | string | yes | Ref is the agent's public id or its org-unique name, from the path. | | `limit` | query | integer | — | Limit caps how many runs come back, newest first. | ## Response | Status | Body | Meaning | | --------- | --------------- | ------- | | `200` | agent.runList | ok | | `default` | problem-details | refused | `200` body — 16 fields. | Field | In | Type | Always | Description | | ------------------------- | ---- | --------------------- | ------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `runs` | body | agent.agentRunView\[] | — | Runs is the agent's executions, newest first. | | `runs[].actor` | body | string | — | Actor is the "org/sub" identity the run was executed and billed AS. | | `runs[].agent` | body | string | — | What an operator needs to answer "what ran, for whom, and what did it do" — and, through traceId, to leave this record for the waterfall of the very same run rather than a search that hopefully lands near it. | | `runs[].completionTokens` | body | integer (int64) | — | CompletionTokens is the same measurement for what the model produced, on the same final completion. | | `runs[].createdAt` | body | string | — | CreatedAt is when the run finished, RFC 3339 in UTC to the second — the duration above already says how long it had been going. | | `runs[].durationMs` | body | integer (int64) | — | DurationMs is wall-clock milliseconds around the completion, including a failover's retries. | | `runs[].error` | body | string | — | Error is why an "ok"-less run failed, as the failing call reported it. | | `runs[].id` | body | string | — | ID is the run's handle, minted as "run\_" + 32 hex characters. | | `runs[].input` | body | string | — | Input is the text the run was given, verbatim. | | `runs[].micro_usd` | body | integer (int64) | — | MicroUSD is what the run spent, integer micro-USD. | | `runs[].model` | body | string | — | Model is the model that actually SERVED this run, which is not always the one the agent is defined on — a failover records what answered. | | `runs[].output` | body | string | — | Output is what the model produced. | | `runs[].promptTokens` | body | integer (int64) | — | PromptTokens is what the gateway reported for the run's FINAL completion, and only that one — a tool loop's earlier rounds are the metering ledger's account, joined by this run's id. | | `runs[].status` | body | string | — | Status is the run's outcome, and there are exactly two: "ok" when the model answered, "error" when it did not. | | `runs[].toolCalls` | body | integer (int64) | — | ToolCalls is how many tool dispatches the run made — a count of ACTIONS, which is a different measurement from the token counts above and from the turns a build reports. | | `runs[].traceId` | body | string | — | TraceID is the trace this run IS, so the record and its spans are one thing to move between: it opens the waterfall for THIS run rather than a search that lands near it. | Failure carries the platform error shape — see [Errors](https://docs.hanzo.ai/docs/errors). ## Examples **CLI** ```bash hanzo agent runs ``` **SDK** **.ts** ```ts import { Configuration, AgentApi } from 'hanzoai';
