Newest first, expired datasets excluded. Datasets belong to the person, not to one X account, so there is no `account_id` parameter here. The account a collection ran as is reported as `x_account_id`. Datasets are kept for 30 days and are created in the SuperX app for now; this API reads them and can copy the people in one into a contact list. ## OpenAPI ````yaml /api-reference/openapi.yaml get /v1/datasets openapi: 3.1.0 info: 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. contact: name: SuperX url: https://superx.so servers: - url: https://api.superx.so security: - apiKey: [] tags: - name: Identity - name: Content - name: Analytics - name: Inspiration - name: Audience - name: Contact Lists - name: Signals - name: Datasets description: | 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. - name: Articles - name: Meta paths: /v1/datasets: get: tags: - Datasets summary: List datasets description: | The audience collections Ask SuperX built for the key owner in the app: the repliers, quoters or reposters of a post, the members of an X list, the owner's own posts or replies, or a research brief.
