act: browse step.

A `BrowseStepInput` to the step's result: the accessibility tree, the text, the markdown, a screenshot's hash, or a download set

Figure 1POST /v1/act/browse_stepspecified

The caller sends BrowseStepInput to /v1/act/browse_step. The platform returns a card whose body is BrowsingStep.

POST/v1/act/browse_stepa task, 202

Drive a browsing step. The call needs the strategy rung under a token with the act grant, and it is served by either, by the size bound.

The route takes BrowseStepInput and returns a card whose body is BrowsingStep.

Request body#

The request body is BrowseStepInput.

field	type	required	note
`session`	`id`	yes
`step`	BrowsingStep	yes

Response#

The route returns a card whose body is BrowsingStep. Every card ends with a foot that states the basis of each number, the scope of the call, and the time when the facts were true. This route runs as a long step and returns a task with status 202. POST /v1/work/status returns the task’s progress, and POST /v1/work/cancel stops the task.

Headers#

header	required	meaning
`Scale-Scope`	yes	the scope the call runs in: tenant/, then /brand/, then /strategy/
`Scale-As-True-On`	no	the date the facts must have been true on; defaults to now
`Scale-As-Known-On`	no	the date the facts must have been known on; defaults to now
`Scale-Key`	no	for a change, the key made from the input; a repeat under the same key returns the unit held and writes nothing

A caller needs the strategy rung and a token with the act grant. The platform or the desktop app serves this route.

Example#

The example sends the smallest body that BrowseStepInput allows. The build validates it against the schema of BrowseStepInput.

Example

curl -X POST https://api.scaleintelligence.co/v1/act/browse_step \
  -H "Scale-Key: $SCALE_KEY" -H "Scale-Scope: tenant/<id>" \
  -H "content-type: application/json" \

// answer.body is a BrowsingStep. answer.foot holds the basis, the scope and the time.

MCP tool#

The MCP tool si.act.browse_step takes the same input and returns the same card. The tool changes data and needs a grant. An MCP host that renders cards draws this card from ui://scale-intelligence/cards/BrowsingStep. The tool’s page describes it.

POST /v1/act/browse_step
Scale-Scope: …
Scale-As-True-On: …
Scale-As-Known-On: …
Scale-Key: …
content-type: application/json

{
  "session": "…",
  "step": {
    "kind": "navigate",
    "reach": "reads only",
    "hop": {
      "stage": "fetched",
      "host": "…",
      "at": "…",
      "job": "…",
      "trace_id": "…",
      "span_id": "…"
    }
  }
}

Without a key, this page shows the request only. The request body is BrowseStepInput, and the route returns a card whose body is BrowsingStep.
