`clinicaltrials_get_study_count`	Get total study count for a query without fetching data. Fast statistics and breakdowns.
`clinicaltrials_get_field_values`	Discover valid values for API fields (status, phase, study type, etc.) with per-value counts.

`clinicaltrials_get_study_results`	Extract outcomes, adverse events, participant flow, and baseline from completed studies. Optional summary mode reduces ~200KB payloads to ~5KB.
`clinicaltrials_find_eligible`	Match patient demographics and conditions to eligible recruiting trials. Provide age, sex, conditions, and location to find studies with matching eligibility criteria, contacts, and recruiting locations.
