# Update a signal agent

> Edit an agent's `name`, `icp_description`, `precision_mode`,
`destination_list_id`, `status`, or any combination. At least one
field is required.

Editing the ICP changes how NEW leads are scored; leads already found
keep their scores. A `destination_list_id` that is not one of your
own usable lists returns 404 `list_not_found`. `status` is `active`
or `paused`: paused agents stop finding leads, and resuming picks up
where the agent left off (a resume is rejected with
`invalid_request` when the agent's stored destination list is gone -
send a new `destination_list_id` first).

The agent's SIGNALS are not edited here: each one resolves its target
upstream, so they have their own endpoints
(`POST /v1/signals/agents/{id}/signals`,
`DELETE /v1/signals/agents/{id}/signals/{signalId}`). Naturally
idempotent, so there is no `Idempotency-Key` support. Works for your
main account or any account linked to it (`account_id`); accounts
shared with you are read-only.




## OpenAPI

openapi: 3.1.0

  title: SuperX API
  version: 1.0.0
  description: >
    The SuperX public API: your Twitter/X content, analytics, audience and

    scheduling data over REST.


    All endpoints require an API key (`Authorization: Bearer sxk_...`) except

    `GET /v1/docs`. Keys are created in the SuperX app under Account > API / MCP
    / CLI

    and are server-side secrets.


    Timestamps are UTC ISO-8601 in both directions; inputs must carry an
    explicit

    `Z` or numeric offset. Every authenticated response carries

    `X-RateLimit-Limit`, `X-RateLimit-Remaining` and `X-RateLimit-Reset`
    headers.

      The audience collections Ask SuperX builds in the app: the repliers,
      quoters or reposters of a post, the members of an X list, your own
      posts or replies, or a research brief.

      Collect a new one with `POST /v1/datasets` (a big collection answers
      202 and finishes in the background), read it, export it, or copy the
      people in it into a contact list you created. Datasets are kept for 30
      days, and the ones Ask SuperX builds in the app show up here too.
  - name: Engage
    description: |
      The account's saved Engage feeds and the candidate posts in them, for
      an agent to score and a person to act on.

      Read-only by design. These endpoints return feed candidates for a
      person to review; replies are written and sent by a person in the
      SuperX app, which is why there is no reply endpoint here. Sending
      spammy, automated, or AI-generated replies that read as inauthentic
      may get your X account suspended under X's inauthentic-behavior
      rules and your SuperX account terminated. AI suggestions must be
      reviewed and meaningfully edited before they are sent, and you are
      solely responsible for what you post. Reply activity is logged and
      may be audited.
  - name: X Lookups
    description: |
      Read any public post, its top replies, any public profile, or an
      account's latest posts LIVE from X, rather than from SuperX's stored
      data.

      These are owner-scoped, so none of them take an `account_id`: nothing
      about a public lookup is per-X-account. They cost the tighter
      live-enrichment allowance and share a daily allowance of 300 live
      lookups with Ask SuperX inside the app, so use them for what you
      actually need rather than to sweep. Repeat lookups within 15 minutes
      may be served from a short-lived server-side cache.
  - name: Tools
    description: |
      The composer helpers from the SuperX app, over the API: rewrite a post,
      edit one selected piece of it, apply one preset rewrite, check a claim,
      or compare two versions.

      Every one of them returns TEXT and writes nothing. Nothing here is
      posted, scheduled or sent; save what you keep with
      `POST /v1/posts/draft` or `POST /v1/scheduled-posts`. They cost AI
      credits, measured from the models' real cost, and spend no live-data
      allowance.
  - name: Media
  - name: Workers
    description: |
      The posts the account's Workers have written, and the three things a
      person does with one: save it as a draft, schedule it, or dismiss it.

      A Worker is a scheduled AI writer set up in the SuperX app. Creating,
      editing and running one stays in the app, so there is no create or run
      endpoint here. What a run produces lands in the app's "To review" queue
      and is read with `GET /v1/workers/suggestions`.

      NOTHING HERE POSTS TO X. Drafting or scheduling a suggestion writes a
      post the user can see in the app and on `GET /v1/scheduled-posts`,
      exactly like the app's own buttons. AI output must be reviewed and
      meaningfully edited by a person before it goes out, so show the text to
      the user and confirm the time before you schedule anything.
  - name: Scheduling
  - name: Tags
  - name: Context
  - name: Queue
  - name: DMs
    description: |
      Queue direct messages into the account's own DM pipeline, and read or
      cancel what is waiting.

      NOTHING HERE SENDS A MESSAGE. `POST /v1/dm/campaigns` enqueues; the
      SuperX app's scheduler is what sends, within the account's daily and
      monthly DM limits, so the create response is counts, not deliveries.
      Unsent messages can be cancelled until the scheduler picks them up.

      You are responsible for the messages you queue. Unsolicited or
      automated bulk DMs may get an X account suspended under X's rules and
      a SuperX account terminated, so confirm the recipient list and the
      exact wording with the person on whose behalf you are queueing.
