## How to call it through Zero

```sh
zero fetch --capability clinical-memoryapi-org-f1e6f499
```

## When to prefer this

Use this endpoint when you need a complete view of all trials run by a single sponsor company, such as for competitive intelligence, pipeline analysis, or tracking a specific pharma/biotech organization's research activity. Prefer this over the condition-based or search endpoints when the primary axis of interest is the sponsor rather than a disease area.

## Known failure modes

- Sponsor name not found or misspelled — returns empty results or error
- Ambiguous sponsor name matching multiple organizations — may return incomplete results
- ClinicalTrials.gov upstream unavailability — service timeout or error response
- Payment failure via x402 protocol — request not processed
