# ONE Engine Text Token Paragraphs (t1)

> ONE Engine Text Token Paragraphs (t1) is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0005/call, status unknown (last checked 2026-10-02).

Splits input text into paragraph-level token segments for downstream processing by autonomous agents.

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-token-paragraphs-t1-57a7c0d5 -d '<json body>'
```

Example prompt: Can you split this article into paragraph-level tokens using ONE Engine? Here's the text: 'The global economy is shifting. New technologies are emerging rapidly. Governments are responding with new policies...'

## When to prefer this

Choose this endpoint when you need lightweight, low-cost paragraph-level text segmentation at scale, especially in autonomous agent pipelines that require pay-per-call micropayment via x402 on Base. It is ideal when you want to avoid spinning up a full NLP stack just to chunk a document into paragraphs.

## Known failure modes

- Text exceeds 50000 character limit — request will be rejected or truncated
- Empty or missing 'text' field — returns validation error
- Payment failure via x402 on Base — request blocked without USDC micropayment
- Malformed JSON body — returns 400 error
- Network timeout on large text inputs

## 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 or chunks, suitable for downstream NLP tasks such as embedding, summarization, or clause-level analysis.
