## 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-diagnostic-8942e15e
```

Example prompt: Run a diagnostic check on the PHD Research and Innovation research database workflow to confirm the payment settled, the content was delivered, and get back the canonical URL and content hash.

## When to prefer this

Choose this endpoint when you need to confirm the operational and payment status of the PHD Research and Innovation research database workflow, particularly to verify that an x402 micropayment has settled and content has been delivered. Useful for diagnostic polling, integration testing, or confirming a prior research database request completed successfully.

## Known failure modes

- Payment not yet settled — paid or settled fields return false
- Content not delivered — delivered field returns false
- Invalid or expired payment — endpoint returns error or ok: false
- Network timeout from Cloudflare Workers edge
- Rate limiting or quota exhaustion returning non-200 status
- Content hash mismatch indicating data integrity issue

## 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 with fields: ok (boolean), paid (boolean), result containing contentHash (sha256 string) and canonicalUrl (image/resource URL), reused (boolean indicating cached result), product (AXIOM machine product name), settled (boolean for payment settlement), provider (provider identifier string), and delivered (boolean confirming content delivery).
