Example prompt: Can you search ClinicalTrials.gov for recruiting studies on glioblastoma and show me up to 15 results including their NCT IDs, phases, sponsors, and enrollment numbers?

## When to prefer this

Use this endpoint when you need fast, structured access to ClinicalTrials.gov data without managing the ClinicalTrials.gov API directly. It is especially useful for filtering by recruitment status, getting a concise summary of trial metadata (NCT ID, phase, sponsor, enrollment), and when you need a pay-per-call model with no API key registration. Prefer this over direct ClinicalTrials.gov API calls when you need a simplified interface with normalized output.

## Known failure modes

- Missing required 'q' query parameter returns an error
- Invalid status filter value may return no results or an error
- Limit outside 1-25 range may be rejected or defaulted
- No trials found for an obscure keyword returns an empty trials array
- ClinicalTrials.gov upstream unavailability may cause failures
- Non-string or malformed query parameter returns a bad request error

## How this service works

ClinicalTrials.gov study search by condition, drug or keyword - NCT id, status, phase, sponsor, enrollment, conditions and start date, filter by recruiting

## Output

Returns a JSON object with the interpreted query string, data source attribution, total number of matching trials, the applied status filter, and an array of trial records each containing NCT ID, status, phase, sponsor, enrollment count, conditions, and start date.
