# ONE Engine Text Paragraph Tokenizer

> ONE Engine Text Paragraph Tokenizer is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-02).

Splits a text input (up to 50,000 characters) into tokenized paragraph segments via a pay-per-call API.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 one-engine-text-paragraph-tokenizer-84801e72 -d '<json body>'
```

Example prompt: Can you split this article into paragraph-level tokens? Here's the text: 'Artificial intelligence is transforming industries worldwide. Companies are investing heavily in machine learning. However, challenges around data privacy remain significant. Regulatory frameworks are still catching up.'

## When to prefer this

Choose this endpoint when you need a lightweight, low-cost ($0.01 USDC) paragraph-level tokenization of text up to 50,000 characters, especially in autonomous agent workflows that already use x402 micropayment infrastructure on Base. It is ideal for preprocessing steps in document pipelines, RAG chunking, or any NLP workflow requiring paragraph segmentation without needing a full-scale NLP library.

## Known failure modes

- Text exceeds 50,000 character limit — input will be rejected or truncated
- Payment failure via x402 on Base — call will not proceed without valid USDC payment
- Empty or missing 'text' field — required field validation error
- Malformed JSON request body — 400 bad request
- Network timeout on Cloudflare Workers edge — transient error requiring retry

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output

Returns a JSON object containing the input text segmented into paragraph-level tokens, likely as an array of paragraph strings or token objects representing each paragraph unit from the original text.
