# PHD Research and Innovation — Research Database Workflow

> PHD Research and Innovation — Research Database Workflow is a paid API for AI agents from phd-research-and-innovation.recondite-coneflower.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-22).

Returns a content hash and canonical URL for a research database resource linked to a selected academic subject, via a paid security endpoint.

## Facts

- Endpoint: GET https://phd-research-and-innovation.recondite-coneflower.workers.dev/api/axiom/x402/security?utm_source=zero.xyz
- Price: $0.002/call

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-f95241dd
```

Example prompt: Can you pull up the research database link for my PhD subject on quantum computing using the AXIOM research workspace — I need the canonical URL and content hash for the verified source?

## When to prefer this

Choose this endpoint when you need a paid, content-verified lookup of a research database canonical URL for a specific academic subject, and require confirmation of payment settlement and a SHA-256 content hash for integrity verification. Prefer this over free academic search APIs when you need provenance guarantees and are operating within an x402 micropayment workflow.

## Known failure modes

- Payment not settled — endpoint returns paid: false or settled: false if USDC payment fails
- Content not delivered — delivered: false if the resource cannot be resolved
- Invalid or missing subject parameter — may return ok: false
- Rate limiting or worker timeout on the Cloudflare Workers edge
- Reused payment token rejected — reused flag may indicate a stale or duplicate request

## How this service works

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

## Output

A JSON object confirming payment settlement, delivery status, and a result object containing a SHA-256 content hash and a canonical URL (pointing to a placeholder or actual resource image/page), along with the AXIOM product name and provider identifier.
