Execute Agent (Streaming)

Execute a research agent using Server-Sent Events (SSE) to receive responses in real time. As the agent generates text, delta events are streamed to the client.

Ideal for long-running research tasks and UI applications that display responses in real time. For simple fire-and-forget use cases, see Execute Agent (Non-Streaming).

New Execution

POST /api/v1/agent/run/stream

Headers

Header	Required	Description
`Authorization`	Yes	API key in `Bearer snorbe_...` format
`Content-Type`	Yes	`application/json`

Request Body

{
  "modelName": "gpt-5-mini-2025-08-07",
  "inputText": "Research the latest AI agent papers",
  "promptKey": "chat-routing",
  "locale": "en",
  "fileUrls": [],

`includeOthersEntities`	`boolean`	No	Include other users’ entities in RAG search. Default: `true`
`extendedContextEnabled`	`boolean`	No	Extended context (uses 80% of model max tokens). Default: `false`
`matrixEditContext`	`object`	No	Matrix edit context (`sourceRunId` + `selection`)
`matrixContinueContext`	`object`	No	Matrix continue context (`sourceRunId`)
`matrixSelectionContent`	`string`	No	Matrix selection XML (`<matrix_selection>` format)

Mention Object

{
  "id": "entity_abc123",
  "type": "entity",
  "label": "GPT-5"
}

Field	Type	Description
`id`	`string`	ID of the referenced item (entity, agent run, or source)

Resume (Restart Existing Run)

Resume execution after a HITL (Human-in-the-Loop) pause, such as plan or report confirmation.

POST /api/v1/agent/run/stream/{runId}

Request Body

{
  "modelName": "gpt-5-mini-2025-08-07",
  "extendedContextEnabled": false
}

Parameters

Parameter	Type	Required	Description
`modelName`	`string`	Yes	Model name
`extendedContextEnabled`	`boolean`	No	Enable extended context. Default: `false`

SSE Event Format

Each event is sent as data: {JSON}\n\n.

config event

Sent once at the start of the stream.

data: {"type":"config","payload":{"runId":"clxyz...","modelName":"gpt-5-mini-2025-08-07","locale":"en","inputText":"..."}}

delta event

Sent each time the agent generates text.

data: {"type":"delta","payload":{"runId":"clxyz...","deltaText":"Generated text","responseText":"Full text so far","stepIndex":0,"modelId":"gpt-5-mini-2025-08-07","provider":"openai"}}

step event

Sent when an execution step completes.

data: {"type":"step","payload":{"runId":"clxyz...","stepIndex":0,"status":"complete","finishReason":"stop","usage":{"inputTokens":1234,"outputTokens":567}}}

browse events

When the browse tool is selected, browser automation progress is streamed as events.

data: {"type":"browse-start","payload":{"runId":"clxyz...","websocketInfo":{"session_id":"browser-session-id","user_id":"user-id","ws_url":"wss://...","token":"..."}}}
data: {"type":"browse-step","payload":{"runId":"clxyz...","stepIndex":1,"action":"click","screenshot":"..."}}
data: {"type":"browse-ask-human","payload":{"runId":"clxyz...","status":"pending","question":"Which menu should I open?"}}
data: {"type":"browse-final","payload":{"runId":"clxyz...","result":"Collected information..."}}
data: {"type":"browse-end","payload":{"runId":"clxyz..."}}

When you receive browse-ask-human, answer through /browser/answer-question using browse-start.payload.websocketInfo.session_id as sessionId. Unlike plan/report/matrix reviews, you do not call /agent/run/stream/{runId} after answering a browser question.

complete event

Sent when the agent finishes. This is the final event in the stream.

data: {"type":"complete","payload":{"runId":"clxyz...","text":"Final response text","finishReason":"stop","status":"completed","model":{"id":"gpt-5-mini-2025-08-07","provider":"openai"}}}

error event

Sent when an error occurs.

data: {"type":"error","payload":{"message":"Error message"}}

Additional internal events

The SSE stream emits every internal event as the agent progresses. In addition to the basic events above (config / delta / step / browse-* / complete / error), the following are also streamed:

Category	Event types
Plan (HITL)	`plan`, `plan-draft-delta`, `plan-draft-complete`, `plan-confirmed`, `plan-rejected`
Report structure (HITL)	`report-structure-draft-delta`, `report-structure-draft-complete`, `report_structure_confirmed`, `report_structure_rejected`
Matrix (HITL)	`matrix-structure-draft-delta`, `matrix-structure-draft-complete`, `matrix-data-preview`, `matrix-data-updated`, `matrix_structure_confirmed`, `matrix_structure_rejected`
Source summarization	`source-summary-start`, `source-summary-delta`, `source-summary-item`, `source-summary-complete`
Graph extraction	`graph-start`, `graph`, `graph-extraction-entity-delta`

Recovering a dropped stream: every event sent over SSE is also persisted as agentRun.process in the database. If your SSE connection drops, call GET /turn/list — turns[].agentRun.process returns the same event timeline, and referenced sources are available in turns[].agentRun.publicSourceAgentRuns / privateSourceAgentRuns.

Examples

curl -N -X POST "https://app.snorbe.deskrex.ai/api/v1/agent/run/stream" \
  -H "Authorization: Bearer snorbe_your_api_key_here" \
  -H "Accept: text/event-stream" \
  -H "Content-Type: application/json" \
  -d '{
    "modelName": "gpt-5-mini-2025-08-07",
    "inputText": "Research the latest AI agent papers",
    "promptKey": "chat-routing",
    "locale": "en"
  }'

Resume Example

# Resume after HITL confirmation
curl -N -X POST "https://app.snorbe.deskrex.ai/api/v1/agent/run/stream/clxxx123" \
  -H "Authorization: Bearer snorbe_your_api_key_here" \
  -H "Accept: text/event-stream" \
  -H "Content-Type: application/json" \
  -d '{"modelName":"gpt-5-mini-2025-08-07"}'

Error Responses

If an error occurs before the stream starts, a regular JSON response is returned instead of SSE.

HTTP Status	Description
401	Invalid API key
400	Validation error
404	Agent run not found for the given `runId` (resume only)
