# ONE Engine Text T5 Line Tokenizer

> ONE Engine Text T5 Line Tokenizer is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0025/call, status unknown (last checked 2026-10-02).

Splits input text into lines using a T5-compatible tokenization scheme, returning line-level token segments for up to 50,000 characters.

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-t5-line-tokenizer-d60f9feb -d '<json body>'
```

Example prompt: Can you split this 10,000-character research paper into tokenized lines using T5-style tokenization so I can feed each segment into my NLP pipeline? Here's the text: [paste text]

## When to prefer this

Choose this endpoint when you need fast, low-cost T5-style line-level tokenization of text up to 50,000 characters in a pay-per-call model via x402 on Base. It is ideal for autonomous agents that need to preprocess documents for transformer pipelines without maintaining a persistent NLP infrastructure. Prefer this over heavier NLP APIs when you only need line segmentation and want minimal per-call cost.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- Empty or missing 'text' field — validation error
- Malformed JSON body — 400 bad request
- Payment not included or insufficient — 402 payment required
- Service unavailable or worker timeout — 5xx error

## 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 text split into line-level token segments, structured for downstream NLP or transformer model consumption. The exact shape is flexible (additionalProperties: true), but typically includes arrays of tokenized lines or line-boundary data.
