## 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 training-lesson-bounded-text-chunks-79d280dd -d '<json body>'
```

Example prompt: Take this training lesson markdown and split it into chunks of at most 800 characters each: '## Objectives
Learn the basics of Python.
## Lesson
Python is a high-level language...
## Exercise
Write a hello world program.'

## When to prefer this

Choose this endpoint when you need deterministic, reproducible text chunking of a training lesson document specifically — no AI generation, hallucination risk, or variability. Ideal for preprocessing educational content for RAG pipelines, vector databases, or LLM context windows where consistent chunk boundaries and size limits are required. Prefer over general-purpose text splitters when working within the datapackvibe ecosystem or when paying per-call at $0.01 USDC via x402 is acceptable.

## Known failure modes

- Input text exceeds 20,000 character limit — request rejected
- max_characters outside allowed range (100–4000) — validation error
- Empty or missing text input — may return empty chunk set
- Malformed input schema — 400-level error response
- Payment failure via x402 protocol — request not processed

## How this service works

Training lesson - Bounded text chunks: Bounded text chunks for Training lesson. 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

An array or sequence of bounded text chunks derived from the supplied training lesson, each guaranteed to be at or under the specified max_characters limit. Processing is deterministic — same input and settings always produce the same chunks. No generative prose or AI-written content is added.
