# ONE Engine Text-to-Paragraphs Tokenizer

> ONE Engine Text-to-Paragraphs Tokenizer is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0065/call, status unknown (last checked 2026-10-02).

Splits and tokenizes input text (up to 50,000 characters) into paragraph-level token 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-to-paragraphs-tokenizer-1d749722 -d '<json body>'
```

Example prompt: Can you split this article into paragraph-level token chunks so I can see how many tokens each paragraph contains? Here's the text: 'The global economy has faced unprecedented challenges in recent years. Central banks around the world have responded with a variety of monetary tools...'

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call tokenization and paragraph segmentation service for text up to 50,000 characters, especially within x402-enabled agent pipelines on Base. It is ideal for preprocessing documents before LLM ingestion or NLP tasks where per-paragraph token awareness is needed.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- Empty or missing 'text' field — validation error returned
- Payment not provided or insufficient USDC — 402 Payment Required response
- Malformed JSON body — 400 Bad Request
- Cloudflare Worker timeout for very large text near the character limit

## 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 units with associated token information, enabling downstream NLP tasks or LLM preprocessing.
