## 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 tinstop-ai-change-advisor-7f76c319 -d '<json body>'
```

Example prompt: Compare my staging domain scan (scan ID: abc123) against my production domain scan (scan ID: xyz789) and give me AI-powered advice on what security or performance issues changed and what I should fix before going live.

## When to prefer this

Use this endpoint when you have already run at least two Tinstop domain scans and want AI-driven insights on what changed between them — ideal for pre/post deployment comparisons, staging-vs-production diffs, or post-migration audits. Prefer this over a raw scan endpoint when you need interpreted, actionable recommendations rather than raw audit data. Best for teams doing continuous deployment who want automated change advisory without managing API keys.

## Known failure modes

- Invalid or expired scan_id returns an error — scan IDs must be from prior Tinstop scans
- Missing required fields (before_scan_id or after_scan_id) causes a validation error
- Payment failure via x402/USDC results in a 402 response and no data returned
- If the two scans are identical, the advisory may return minimal or no actionable changes
- Mode parameter set to an unsupported value may produce unexpected results

## How this service works

Tinstop is a machine-payable Website Intelligence API for domain security and performance audits: DNS, SSL/TLS, HTTP security headers, SPF/DKIM/DMARC email authentication, and Google PageSpeed. Pay per call with x402 using USDC on Base. No accounts or API keys.

## Output

An AI-generated advisory report comparing two domain scans or two domains, highlighting security and performance changes, regressions, improvements, and prioritized recommendations for remediation.
