# Technical Design – Bounded Text Chunks

> Technical Design – Bounded Text Chunks is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-14).

Splits a technical design document (Markdown or plain text) into bounded text chunks of a specified maximum character length using deterministic processing.

## 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 technical-design-bounded-text-chunks-581baf4f -d '<json body>'
```

Example prompt: Split my technical design document into chunks of at most 800 characters each — here's the content: '## Architecture
We use a microservices layout with three core services...
## Interfaces
REST APIs are exposed over HTTPS...
## Trade-offs
Latency vs consistency was the main trade-off...'

## When to prefer this

Choose this endpoint when you need deterministic, reproducible chunking of technical design documents (Markdown or plain text) with a strict character-length guarantee per chunk, and you do not need generative rewriting or summarization. Ideal as a preprocessing step before vector embedding, LLM ingestion, or paginated display of technical documentation.

## Known failure modes

- Input text exceeds 20,000 character limit — request rejected
- max_characters below minimum of 100 or above maximum of 4,000 — validation error
- Malformed or empty input text — may return empty chunk array or error
- Payment not provided or insufficient — x402 payment required response

## How this service works

Technical design - Bounded text chunks: Bounded text chunks for Technical design. 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 technical design document, each guaranteed not to exceed the requested maximum character length. Processing is deterministic — no generative content is added or removed; the output is a faithful segmentation of the supplied text.
