## 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 whatchuneed-clinical-trials-search-65584a31 -d '<json body>'
```

Example prompt: Can you find all currently recruiting clinical trials for Type 2 diabetes?

## When to prefer this

Use this endpoint when you need structured, programmatic access to clinical trial data filtered by condition and status without scraping ClinicalTrials.gov directly. Best for agents that need to surface trial options for patients, researchers, or competitive intelligence use cases and require a pay-per-call model with no subscription overhead.

## Known failure modes

- Missing required 'condition' field returns a 400 validation error
- Obscure or misspelled condition names may return zero results
- Invalid 'status' enum values may be ignored or return an error
- Upstream ClinicalTrials.gov data may be stale or incomplete
- Payment failure via x402 protocol results in 402 response with no data
