# 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, $0.0007/call, status unknown (last checked 2026-10-02).

Strips blank lines from a block of text, normalizing whitespace by removing empty lines 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-normalize-remove-blank-lines-1a8e855d -d '<json body>'
```

Example prompt: Clean up this text by removing all blank lines from it: [paste your text here].

## When to prefer this

Choose this endpoint when you need a lightweight, low-cost ($0.0007 USDC) pay-per-call operation to strip blank lines from text within an autonomous agent workflow on Base, particularly when you want minimal overhead and a simple transformation without spinning up local text-processing logic.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- Missing required 'text' field — validation error
- Payment failure via x402 — 402 response returned before processing
- Empty string input may return trivially identical output

## How this service works

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

## Output

Returns a cleaned version of the input text with all blank lines removed, as a JSON object containing the normalized text string.
