## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## ClinicalTrials.gov Scraper Pro

Search the full ClinicalTrials.gov registry (500K+ studies) by condition, drug, intervention, sponsor, phase, status or geography, and get one clean JSON row per trial: NCT ID, status, phase, sponsor, enrollment, start and completion dates, eligibility, keywords, official brief summary and every trial site.

No account and no API key: set your filters, run it, and get clean results in seconds.

### Why this one

The segment's biggest listing, parseforge/clinicaltrials-scraper, hides its event pricing and holds 47 users; most alternatives expose little more than title and status. **ClinicalTrials.gov Scraper Pro gives you every engagement filter the registry supports (condition, intervention, sponsor, phase, status, geography) plus per-trial site lists, at $2.00 per 1,000 trials, in line with the category's published leader price.**

### Input

| Field | Type | Default | Description |
|---|---|---|---|
| `condition` | string | `melanoma` | Disease or condition to search for |
| `query` | string | ``| Free-text search against trial titles |
| `intervention` | string |`` | Drug, device or procedure, e.g. `pembrolizumab` |
| `sponsor` | string | ``| Lead sponsor, e.g. `Pfizer` |
| `phase` | array | `[]` | Phases to keep, e.g. `PHASE3` (empty = all) |
| `statuses` | array | `["RECRUITING"]` | Overall statuses (empty = all) |
| `geoArea` | string |`` | Geo expression, e.g. `distance(100mi,Boston,MA)` |
| `maxItems` | number | `10` | Hard cap on trials saved |
| `includeLocations` | boolean | `true` | Save every trial site per row |
| `includeSummary` | boolean | `true` | Save the official brief summary |

### Output

| Field | Description |
|---|---|
| `nctId` | Trial's NCT identifier |
| `briefTitle` / `officialTitle` | Titles |
| `overallStatus` | RECRUITING, COMPLETED, ACTIVE_NOT_RECRUITING, ... |
| `phase` | Phase(s), comma-joined |
| `studyType` | INTERVENTIONAL or OBSERVATIONAL |
| `leadSponsor` / `sponsorClass` | Sponsor name and INDUSTRY/OTHER class |
| `collaborators` | Collaborating organizations |
| `enrollmentCount` / `enrollmentType` | Planned/actual enrollment |
| `startDate` / `primaryCompletionDate` / `completionDate` | Key dates |
| `lastUpdatePosted` | Registry last-update date |
| `conditions` | Conditions under study |
| `interventions` | Intervention names |
| `sex` / `minAge` / `maxAge` / `healthyVolunteers` | Eligibility |
| `keywords` / `briefSummary` | Registry keywords and summary |
| `locations` | Trial sites (facility, city, state, country, status) when enabled |
| `url` | Direct clinicaltrials.gov/study link |

### Pricing

Pay per event:

| Event | Price | When |
|---|---|---|
| actor-start | $0.005 | Once per run |
| result | $0.002 | Per trial row saved to the dataset |

**$2.00 per 1,000 trials.**

### Use cases

- Pharma and biotech pipeline tracking: monitor any sponsor's recruiting trials by phase and geography
- Competitive intelligence: watch a drug's trial landscape across the full registry
- Site selection: pull trial sites with facility, city, state and country per study
- AI/LLM datasets: structured trial rows with summaries, ready for RAG pipelines

### FAQ

**Do I need a ClinicalTrials.gov API key?**
No. The actor uses the official public v2 API; no key, no login.

**Can I combine filters?**
Yes. Condition, title search, intervention, sponsor, phases, statuses and geography all combine in one query.

**How many trials can I pull?**
Up to `maxItems` (hard cap, 100,000), paginated 100 per page behind the scenes.

**What counts as a billed result?**
Each trial row saved to the dataset. Filtered or duplicate rows are never saved and never billed.

```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
