## 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 avedaris-vendor-what-changed-report-6f4ff881 -d '<json body>'
```

Example prompt: Before I pay acme-supplies.com this invoice, can you check if anything has changed on their domain since we last looked — I want to see any before/after differences and how serious they are?

## When to prefer this

Use this endpoint when you need to detect changes on a specific supplier or vendor domain before authorizing a payment, reorder, or new supplier onboarding. It is specifically designed for procurement and vendor due diligence workflows where change detection with severity triage matters. Prefer this over a general web-scraping endpoint because it maintains a stored previous snapshot for diffing, provides structured before/after values, severity ratings, and a historical log — all in one call. It complements the AveDaris Company Intelligence endpoint, which provides broader company research rather than point-in-time change detection.

## Known failure modes

- Invalid or non-resolvable domain returns an error
- Data source temporarily down — call is uncharged and an error is returned
- Domain has never been checked before — no previous snapshot available for diffing
- Malformed input (e.g. domain too short or too long) rejected with validation error
- Domain resolves but returns no meaningful public signals

## How this service works

Supplier what-changed report: send a vendor domain; get a fresh snapshot, every field that changed since the previous stored check with before/after values and a high/medium/low severity, a one-line summary, and the last recorded changes for that domain. Use it before paying or re-ordering from a supplier. Public signals only. Uncharged if a data source is down. $0.01 USDC per call on Base.

## Output

A structured report containing: a fresh snapshot of the vendor domain, a list of every field that changed since the previous stored check with before and after values, a severity label (high/medium/low) for each change, a one-line summary of what changed, and the last recorded historical changes for that domain. No charge is applied if a data source is unavailable.
