# ONE Engine Text Token Sentence Splitter

> ONE Engine Text Token Sentence Splitter 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 input text into individual sentences using a token-based NLP pipeline, returning a list of sentence segments.

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-sentence-splitter-aa9d4a6e -d '<json body>'
```

Example prompt: Split this article into individual sentences: 'Artificial intelligence is transforming industries. Companies are investing heavily in automation. The future remains uncertain but promising.'

## When to prefer this

Choose this endpoint when you need lightweight, low-cost sentence tokenization as a preprocessing step for NLP tasks. At $0.01 per call via x402 on Base, it suits autonomous agents that need to split text programmatically without spinning up a local NLP library. Prefer it for short-to-medium text blocks (up to 50k chars) where sentence boundary detection is a utility step in a larger pipeline.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- Empty or missing 'text' field — validation error
- Payment failure via x402 — 402 response before processing
- Malformed JSON body — 400 bad request
- Ambiguous sentence boundaries in non-standard text (e.g. abbreviations, code) — may produce unexpected splits

## 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 individual sentences, likely as an array of sentence strings or tokens with boundary metadata, enabling downstream per-sentence processing.
