Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 clinical-memoryapi-org-b8546e3d
```

Example prompt: Pull all clinical trials listed on ClinicalTrials.gov for non-small cell lung cancer so I can see the full competitive landscape — who's running trials, what phases they're in, and what interventions are being tested.

## When to prefer this

Use this endpoint when you need a broad survey of ALL trials for a given disease or condition, rather than searching by sponsor, intervention, or a specific NCT ID. Ideal for competitive landscape analysis, pipeline mapping, or understanding the full scope of research activity in a disease area.

## Known failure modes

- Condition name not recognized or too ambiguous — returns empty results or requires normalization
- Rate limiting or payment failure with x402 protocol — returns 402 Payment Required
- Very broad condition terms (e.g. 'cancer') may return extremely large result sets
- Misspelled condition names yield no results
- Niche or rare disease names may return few or no results

## How this service works

All clinical trials for a specific medical condition. Get competitive landscape of trials in a disease area.

## Output

A list of clinical trials for the specified medical condition, including trial IDs (NCT numbers), titles, phases, statuses, sponsor names, and intervention details — giving a comprehensive view of the competitive trial landscape for that disease area.
