## 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-workflow-seo-8123472b
```

Example prompt: Can you find qualified research websites and pull up the linked research database for the subject of machine learning in healthcare — I need the canonical resource URL and confirmation it was delivered?

## When to prefer this

Use this endpoint when you need to quickly locate qualified, SEO-vetted websites and access a linked research database for a specific academic or research subject. It is best suited for PhD-level or graduate research workflows where a canonical resource URL and delivery confirmation are needed. Prefer this over generic web search when you want a structured, payment-gated result with provenance metadata (content hash, provider, settlement status).

## Known failure modes

- Payment not settled — endpoint requires $0.005 USDC via x402 protocol; unpaid requests will not return results
- Invalid or unsupported subject query — may return an empty or null canonical URL
- Content hash mismatch — delivered resource may not match expected content
- Service unavailable on the workers.dev infrastructure — transient 5xx errors possible
- Reused/cached result returned when fresh data was expected

## 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 settlement, delivery status, a SHA-256 content hash of the research resource, a canonical URL pointing to the identified research database or website, the AXIOM machine product label, and the provider name. Includes a 'reused' flag indicating whether a cached result was returned.
