## 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-email-sequence-generator-be0b9303 -d '<json body>'
```

Example prompt: Write me a 5-email launch sequence for my project management SaaS called TaskFlow — the audience is busy freelancers who hate complexity, and the tone should be friendly and direct with a soft sell at the end.

## When to prefer this

Choose this endpoint when you need a ready-to-ship multi-email sequence crafted for conversion — especially for product launches, onboarding flows, or sales funnels — and want copy that reflects a specific audience and tone without manual editing. It is ideal for agents automating marketing workflows that require email copy at the sequence level rather than individual one-off messages.

## Known failure modes

- Empty or missing 'input' field returns a validation error
- Input exceeding 8000 characters is rejected
- Insufficient USDC balance causes payment failure before generation
- Vague or extremely short prompts may produce generic, low-quality copy
- Network congestion on Base may delay payment confirmation
- Service timeout if the generation model is under heavy load

## How this service works

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

## Output

Returns a JSON object containing a job ID, the full generated email sequence copy as a string, and a payment receipt with the transaction hash, amount in USDC base units, and the network used.
