## 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 proofline-launch-risk-check-f1d0fae7 -d '<json body>'
```

Example prompt: Can you run a Proofline launch risk check on my SaaS pricing page at https://myapp.com/pricing and tell me what's blocking conversions, how severe each issue is, and whether the page is ready to go live?

## When to prefer this

Choose this endpoint when you need a fast, structured, evidence-backed audit of public product or landing pages before launch or before scaling ad spend — especially when you want Linear-ready, actionable defect tickets with severity rankings rather than generic UX advice. Prefer this over manual review or generic SEO tools when the goal is conversion-blocking issue detection with a clear go/no-go verdict.

## Known failure modes

- Target URL is unreachable or returns non-200 status, resulting in no pages audited
- Pages behind authentication cannot be crawled, producing incomplete results
- Placeholder or localhost URLs produce empty or meaningless audits
- Rate limiting or payment failure (x402) if USDC balance is insufficient
- Dynamic/JS-heavy pages may not be fully rendered, missing client-side issues

## How this service works

Evidence-backed product validation and SaaS conversion audits, including a fixed $250 validation sprint with reproducible, Linear-ready defects.

## Output

Returns a JSON object with an overall directional score out of 100, a verdict (e.g. 'needs-repair' or 'ready'), a count of pages audited, and a ranked priority queue of issues — each with a unique ID, repair instruction, affected page URL, issue category, evidence quote, and severity level — plus a final launch decision statement.
