## 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 phd-research-and-innovation-research-database-site-finder-730b630d
```

Example prompt: Can you find qualified research websites and pull up the linked research database for the subject of CRISPR gene editing?

## When to prefer this

Use this endpoint when you need to quickly discover curated, qualified websites for a specific academic or PhD research subject and want a direct link to the associated research database entry. Prefer this over general web search when you need vetted, research-grade sources tied to a known database index, especially in an automated research workflow.

## Known failure modes

- Invalid or missing subject query returns an error or empty result
- Payment not settled results in unpaid/undelivered flags in response
- Network timeout to the upstream AXIOM provider
- Subject has no qualified websites indexed, returning no canonical URL
- Rate limiting or quota exceeded on the underlying worker

## How this service works

A focused research workspace for finding qualified websites and opening the linked research database for a selected subject.

## Output

Returns a JSON object confirming payment and delivery, including a content hash (SHA-256), a canonical URL pointing to the research database resource for the requested subject, the AXIOM product name, provider identity, and flags indicating whether the result was settled, delivered, and whether a cached result was reused.
