version: Get API version

Description

Returns the current API version and data timestamp. This is the simplest endpoint in the API and serves as a health check - it doesn't require any parameters and always returns the API version string (e.g., "2.0.5") and the timestamp when the data was last updated. Call this endpoint when you want to verify the API is online, check which version is deployed, or confirm your integration is working before making more complex queries. The response is always small and fast, making it ideal for monitoring and testing connectivity.

From spec: Returns the current API version and data timestamp.

    print(item)

const resp = await fetch("https://clinicaltrials.gov/api/v2/version");
const data = await resp.json();
