How much does it cost?

The Actor is billed by Apify according to the pricing shown on the Pricing tab of this page. Runs are small and fast, and the Apify Free plan includes monthly platform credits so you can try it at no cost. You can set a maximum cost per run, and the Actor stops cleanly when that limit is reached.

Notes and limitations

• Data comes from the official ClinicalTrials.gov API v2 (US National Library of Medicine, public domain).
• Fill in at least one of condition, intervention or keyword; combine them to narrow the search.

Tips

• Start with a small test run, then scale up the input.
• Use Schedules to automate recurring runs and Webhooks or Integrations to deliver the data where you need it.
• Call the Actor from your code with the Apify API or the official JavaScript and Python clients.
