## When to prefer this

Use this endpoint when an AI agent needs to match a patient profile or clinical scenario to relevant recruiting clinical trials, especially in healthcare or medical research workflows. It is particularly useful when you need a quick, pay-per-call lookup without maintaining a subscription to a dedicated clinical trial matching service.

## Known failure modes

- Vague or underspecified patient input may return low-relevance matches
- No trials found for highly specific or rare conditions
- Input missing required clinical details may return an empty result set
- Upstream clinical trial database unavailability may cause errors
- Generic or non-medical input may result in unhelpful or null results
