## 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 longevitypulse-clinical-trials-search-9083f349
```

Example prompt: Find me active clinical trials testing rapamycin or metformin for longevity near San Francisco — I'm 52 years old and want to know if I'm eligible and how to apply.

## When to prefer this

Choose this endpoint when a user wants to find real, currently active longevity or anti-aging clinical trials — especially for specific interventions like rapamycin, metformin, NMN, or senolytics — including eligibility and enrollment details. Prefer over generic ClinicalTrials.gov search when the use case is specifically longevity/geroscience focused and the agent needs pre-filtered, relevant results with structured eligibility and application guidance.

## Known failure modes

- No matching trials found for the specified condition or intervention — returns empty results
- Invalid or unrecognized intervention name yields no results
- Location too narrow or misspelled returns empty set
- ClinicalTrials.gov upstream unavailability causes timeout or error
- Payment of 0.1 USDC not confirmed — 402 Payment Required response

## How this service works

Longevity clinical trial search / anti-aging trial finder for research and health agents. Finds active trials from ClinicalTrials.gov by condition, intervention (rapamycin, metformin, NMN, senolytics, caloric restriction), or location worldwide, with eligibility and how to apply. Health intelligence, not medical advice.

## Output

A list of active anti-aging and longevity clinical trials from ClinicalTrials.gov matching the query, including trial name, status, intervention being tested, eligibility requirements (age range, health conditions, exclusion criteria), location, and instructions for how to apply or enroll.
