## 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 superscribe-landing-page-copy-generator-fec4075a -d '<json body>'
```

Example prompt: Write me high-converting landing page copy for TaskFlow, a project management tool built for freelancers that helps them track client work and deadlines in one place — the one action I want visitors to take is start a free trial.

## When to prefer this

Choose this endpoint when you need ready-to-ship landing page copy generated in seconds from a brief product description, especially for SaaS, apps, or tools with a clear CTA. Prefer this over generic LLM prompting when you want copy specifically optimized for conversion and structured for immediate use on a landing page.

## Known failure modes

- Empty or too-short input string (minLength:1 violated) — returns validation error
- Input exceeding 8000 characters — returns schema validation error
- Insufficient USDC balance or failed x402 payment — returns 402 Payment Required
- Vague or ambiguous product description may result in generic, low-quality copy
- Service unavailable or timeout — returns 5xx error with no output

## How this service works

Copy that converts. Landing pages, launch threads and emails, written to ship.

## Output

Returns a jobId, the generated landing page copy as a string (headlines, subheadings, body copy, and CTA text optimized for conversion), and a payment receipt containing the transaction hash, amount in USDC, and network details.
