# ONE Engine Text Segment Pack Tier 2

> ONE Engine Text Segment Pack Tier 2 is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0009/call, status unknown (last checked 2026-10-02).

Segments and packs input text into structured chunks at the Tier 2 processing level, optimized for autonomous agent pipelines.

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-segment-pack-tier-2-ef31549a -d '<json body>'
```

Example prompt: Can you segment this article into packed text chunks using the Tier 2 level so I can feed each piece into my embedding pipeline? Here's the text: 'Artificial intelligence is transforming industries across the globe, from healthcare to finance, enabling new automation and decision-making capabilities.'

## When to prefer this

Choose this endpoint when you need low-cost, pay-per-call text segmentation for autonomous agent pipelines operating on Base via x402 micropayments. It is ideal for preprocessing text before embedding, indexing, or summarization at Tier 2 fidelity. Prefer it over higher-tier endpoints when cost efficiency matters more than maximum segmentation sophistication.

## Known failure modes

- Missing or empty 'text' field returns a validation error
- Extremely long input strings may be truncated or rejected
- Payment failure via x402 results in a 402 Payment Required response before processing
- Malformed JSON body returns a 400 Bad Request
- Temporary worker downtime may cause 503 Service Unavailable

## How this service works

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

## Output

A JSON object containing a 'tier' field (value 2) and a 'result' field with the tier-dependent segmented and packed text output — typically structured text chunks derived from the input string.
