## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability saylor-innovations-medical-reference-clinical-trial-search-e3fae238
```

Example prompt: Can you search ClinicalTrials.gov for any ongoing or recruiting clinical trials for Type 2 diabetes?

## When to prefer this

Use this endpoint when an agent needs to quickly surface clinical trial data for a specific medical condition without directly integrating with the ClinicalTrials.gov API. It is ideal for health information agents, medical research assistants, and patient advocacy tools that need structured trial data in JSON format at low per-call cost.

## Known failure modes

- No trials found for obscure or misspelled condition names — returns empty trials array
- Overly broad condition terms may return large result sets with limited filtering
- ClinicalTrials.gov upstream unavailability may cause timeouts or empty responses
- Missing required 'condition' query parameter may result in an error or unfiltered response

## How this service works
