## 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 animica-clinical-trials-search-fea72ee0 -d '<json body>'
```

Example prompt: Can you find RECRUITING Phase 2 clinical trials for breast cancer within 100 km of San Francisco (lat 37.7749, lon -122.4194)?

## When to prefer this

Choose this endpoint when you need geospatially-filtered clinical trial discovery with support for structured filters like phase, status, sponsor, and condition in a single pay-per-call API — ideal for agents operating without a ClinicalTrials.gov API key or needing a simple, cost-transparent, x402-compatible interface.

## Known failure modes

- Invalid or out-of-range lat/lon coordinates return an error or empty results
- Unknown phase or status enum values may cause filtering to fail or return no results
- Very large radius values may time out or return too many results
- Payment failure (insufficient USDC balance) blocks the call before execution
- Missing required fields such as query or condition with no fallback may return empty result sets
