## 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 research-note-bounded-text-chunks-89af1286 -d '<json body>'
```

Example prompt: Take this research note and split it into chunks of no more than 800 characters each — it's about 3,000 characters of Markdown with sections for Question, Method, and Findings.

## When to prefer this

Choose this endpoint when you need deterministic, reproducible chunking of a research note in Markdown or plain text format — especially when you require consistent chunk boundaries for downstream embedding, indexing, or review workflows. Prefer this over generative summarization tools when you want the original text preserved verbatim in segments rather than paraphrased or condensed.

## Known failure modes

- Input text exceeds 20,000 character limit — request rejected
- max_characters value outside 100–4000 range — validation error
- Empty or missing text field — no chunks returned
- Malformed request body — HTTP 400 error

## How this service works

Research note - Bounded text chunks: Bounded text chunks for Research note. 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 of bounded text chunks derived from the input research note, each not exceeding the specified max_characters limit. Processing is deterministic — the same input always produces the same output chunks. No generative content or fact-checking is applied.
