## 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-launch-thread-generator-59c18043 -d '<json body>'
```

Example prompt: Write me a launch thread for my new AI productivity tool called FocusForge — it helps remote workers block distractions and enter deep work in one click, launching on Product Hunt this Thursday. Keep the tone punchy and founder-led, and include the link https://focusforge.app.

## When to prefer this

Choose this endpoint when you specifically need a Twitter/X launch thread — not a landing page or email — and want copy that is optimized for conversion and engagement at launch. It is ideal for founders, indie hackers, and marketers who want to ship quickly without hiring a copywriter. Prefer this over general LLM prompting when you want a purpose-built, launch-optimized output with on-chain payment and receipting.

## Known failure modes

- Empty or too-short input string (below minLength of 1) returns validation error
- Input exceeding 8000 characters triggers maxLength violation
- Payment failure on-chain results in 402 response and no content generated
- Vague or ambiguous input may produce generic copy that lacks specificity
- Network or facilitator timeout may result in no jobId returned

## How this service works

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

## Output

Returns a JSON object with a jobId, the generated launch thread copy as a string (output), and a payment receipt containing the transaction hash, amount in USDC base units, and network name.
