How much does it cost to use ClinicalTrials.gov Search API?

FAQ
Is the data current? Yes. Each run queries the live registry.
Is this medical advice? No. It is registry data for research. Do not use it to make treatment decisions.
Why did my search return nothing? Check the spelling or loosen the filters. Empty results are not charged.
Is it legal?
The actor reads public, open-licence or government data only and does not collect private information. You are responsible for using the results in line with the source's terms and applicable laws.
Use it with AI agents (MCP)
This actor is agent-ready: it is a plain tool with a documented JSON input and a flat JSON output, so Claude, ChatGPT, Cursor and other agents can call it through the Apify MCP server.
Add it to an MCP client with this URL (Apify account or agentic payment required):
Example prompt: "Use the ClinicalTrials.gov Search API tool with the example input below and summarise the results."
Calls are pay per event ($0.002 per trial), so an agent can estimate the cost before it runs. Empty or failed lookups return a status record instead of failing the run.
