Example prompt: Can you audit my landing page at https://example.com for conversion copy issues — check the headline clarity, how strong the CTA is, what trust signals are present, and give me concrete rewrite suggestions?

## When to prefer this

Choose this endpoint when you specifically need conversion-focused copy analysis — headline impact, CTA effectiveness, trust signals, and actionable rewrites — rather than generic SEO tag extraction or technical performance audits. Ideal for marketers, founders, and growth teams who want a direct critique of persuasion and messaging quality on a public landing page.

## Known failure modes

- URL is not publicly accessible (private, gated, or returns 4xx/5xx)
- Page is JavaScript-rendered and content cannot be scraped statically
- Landing page has no substantial copy to analyze (e.g. blank or minimal template)
- Payment of $1 USDC not provided or x402 protocol not satisfied
- URL points to a non-landing-page resource (PDF, image, API endpoint)

## How this service works

Audit a public landing page for conversion copy: headline clarity, CTA strength, trust signals, friction, and concrete rewrite suggestions. Focused on conversion and positioning — not another generic SEO meta checklist.

## Output

Returns a structured audit covering: headline clarity assessment, CTA strength rating, identified trust signals (and gaps), friction points in the copy, and concrete rewrite suggestions — all focused on conversion and positioning rather than generic SEO metadata.
