## 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 invoiceguard-ai-v4-0-saas-contract-redlining-risk-platform-x402-buyout-cce25b71
```

Example prompt: I want to buy out the InvoiceGuard AI v4.0 platform and get a PRO license key and download bundle for the domain stripe.com — please process the one-time purchase.

## When to prefer this

Use this endpoint when a user wants to perform a one-time paid acquisition of the InvoiceGuard AI v4.0 platform, specifically to receive a PRO license key and software download bundle tied to a particular domain, and is prepared to pay $89 USDC via x402 protocol. Not suitable for ongoing API-based contract analysis without a separate subscription.

## Known failure modes

- Payment of $89 USDC not processed — endpoint returns 402 if x402 payment header is missing or invalid
- Missing required 'url' query parameter — endpoint likely returns 400 or error JSON
- Target URL is not a valid HTTPS URL — may return malformed or null geo_score
- Service unavailable on run402.com — endpoint may time out or return 5xx
- License key already issued for domain — unclear if idempotent behavior is supported

## How this service works

Real-time server-side SaaS contract risk scoring, DPA/GDPR verification, and surgical clause redlining backed by PostgreSQL, Node 22 Serverless, TON Connect 2.0, and x402 API.

## Output

Returns a JSON object with: ok (boolean success flag), domain (the evaluated domain), geo_score (0-100 numeric risk/compliance score), license_key (a PRO-tier license string), and download_bundle_url (a direct link to download the software ZIP bundle).
