## 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 newsletter-bounded-text-chunks-splitter-143e3496 -d '<json body>'
```

Example prompt: Take this newsletter draft and split it into chunks of no more than 800 characters each: '## Introduction\nWelcome to our monthly update...\n## Updates\nThis month we shipped three features...\n## Call to action\nSign up now to get early access.'

## When to prefer this

Choose this endpoint when you need deterministic, reproducible splitting of newsletter-formatted Markdown or plain text into character-bounded chunks, especially for pipelines where consistency matters. It is ideal for pre-processing newsletter content for email platforms, review workflows, or multi-step publishing systems. Prefer it over generative tools when you do not want AI-rewritten prose — only mechanical segmentation.

## Known failure modes

- Input text exceeds 20,000 characters — request rejected
- max_characters value outside the 100–4000 range — validation error
- Empty or missing text field — may return empty chunks or error
- Malformed Markdown that causes unexpected chunk boundaries
- Payment not completed via x402 protocol — endpoint not accessible

## How this service works

Newsletter - Bounded text chunks: Bounded text chunks for Newsletter. Supplied Markdown or plain text, up to 20,000 characters. Deterministic processing and document templates; no generative prose or fact checking. One of 25 profiles or calculations across 20 shared operations in this sector. 0.01 USDC includes one bounded bounded text chunks deliverable.

## Output

A set of bounded text chunks derived from the input newsletter Markdown or plain text, where each chunk does not exceed the specified max_characters limit (100–4000 characters). The output is produced deterministically — same input always yields the same chunks — with no generative prose or fact-checking applied.
