# ONE Engine Text Normalize – Remove Blank Lines

> ONE Engine Text Normalize – Remove Blank Lines 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).

Strips or collapses blank lines from a block of text, returning a clean, blank-line-free version of the input.

## 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-normalize-remove-blank-lines-90ed215a -d '<json body>'
```

Example prompt: Clean up this text by removing all blank lines: [paste text here]. I need a tidy version with no empty lines between the content.

## When to prefer this

Choose this endpoint when you need a cheap, fast, pay-per-call operation to strip blank lines from text as part of a pipeline — especially in autonomous agent workflows using x402 on Base where microtransactions are acceptable. Ideal for preprocessing steps before NLP analysis, storage, or display, when you don't want to run local text-cleaning logic.

## Known failure modes

- Input text exceeds 50,000 character limit — request rejected
- Missing required 'text' field — validation error returned
- Empty string input — may return empty or unchanged result
- Payment failure via x402 — 402 response, no processing performed

## 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 normalized version of the input text with all blank lines removed or collapsed, ready for downstream processing or storage.
