Why use this actor

Whole corpus or a slice — 588k+ studies; pull everything via cursor pagination, or filter to your therapeutic area.
One study per row, with a flat header (nct_id, brief_title, overall_status, phase, lead_sponsor, start_date) plus the full raw study object (protocol, derived, results) preserved.
No login, no key. Clean JSON API.

Input

Field	Type	Description
`conditionQuery`	text	Disease/condition, e.g. `breast cancer`.
`termQuery`	text	Other terms (drug, sponsor, keyword).
`status`	multi-select	Filter by overall status (Recruiting, Completed, Terminated, …).
`pageSize`	int	1–1000 (default 1000).
`maxItems`	int	0 = all matching.

status is a dropdown of the valid ClinicalTrials statuses — no need to know the API enum strings.

Output — `CLINICAL_TRIAL`

Envelope (_input, _source, _scrapedAt) + recordType: "CLINICAL_TRIAL" + flat header fields, then the raw study object verbatim:

{
  "_input": "cond=breast cancer; status=RECRUITING",
  "_source": "S1-ctgov-v2",
  "_scrapedAt": "2026-06-03T10:00:00Z",
  "recordType": "CLINICAL_TRIAL",
  "nct_id": "NCT01234567",
  "brief_title": "...",
  "overall_status": "RECRUITING",
  "phase": "PHASE2",
  "lead_sponsor": "...",
  "start_date": "2026-01-01",
  "protocolSection": { "...": "..." },
  "derivedSection": { "...": "..." },
  "hasResults": false
}

How it works

Your filters become v2 query params (query.cond, query.term, filter.overallStatus).
The actor pages through results with the nextPageToken cursor (pageSize up to 1000).
Each study streams into the dataset.

Known limits

Public API, no WAF; datacenter IP is fine. Backs off on HTTP 429.
Verified live 2026-06-03: totalCount 588,273; cursor pagination via nextPageToken confirmed.
