## 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 medapi-trial-match-clinical-trial-matching-endpoint-b06fdf06 -d '<json body>'
```

Example prompt: Can you find clinical trials available for stage 3 non-small-cell lung cancer and give me an AI analysis of which ones are the best match?

## When to prefer this

Choose this endpoint when you need to find active or recruiting clinical trials for a specific medical condition AND want an AI-powered assessment of trial relevance — not just a raw data dump. Ideal for patient-facing assistants, medical researchers, or care navigation tools that need both structured trial data and intelligent matching commentary in one call.

## Known failure modes

- Missing required 'condition' field returns validation error
- Unrecognized or misspelled condition name may return zero results
- Downstream ClinicalTrials.gov API unavailability causes lookup failure
- LLM analysis component may fail independently while trial list still returns
- Payment failure via x402 returns 402 status before query is processed
