# ClinicalTrials.gov API

> ClinicalTrials.gov returns clinical trial records, locations, and sponsor studies as a workflow and API.

Search trials finds studies by condition or medicine, with optional location, distance, recruitment status, and phase filters. Get trial returns a public study record using an NCT number or title, including treatments, arms, locations, and public contacts. List company trials returns studies for a sponsor, with optional phase, status, and condition filters.

## Methods

### Get trial

Operation `get_trial`, version 1. 1 credit per completed call. Failed calls without a completed billing receipt are free; completed work can remain charged if delivery is interrupted.

Get the full public record for a clinical trial by NCT number or title. For ambiguous titles, returns the closest matching registered title. Dates without a recorded day are returned as null.

**Input**

| Field | Type | Required | Example | Description |
|---|---|---|---|---|
| `trial` | string | yes | `"NCT05175625"` | The trial title or NCT trial number, for example NCT04368728. |

Replace `YOUR_API_KEY` with a Fous API key. To create one, open Developers at the bottom of Fous Studio, turn on Developer mode, then go to API keys (https://app.fous.com/keys). Change the values in `input` to run the same tool on new data.
