# ONE Engine – Remove Empty Lines

> ONE Engine – Remove Empty Lines is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

Strips all empty lines from a block of text and returns the cleaned text along with the resulting line count.

## 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-remove-empty-lines-197ab990 -d '<json body>'
```

Example prompt: Can you clean up this block of text by removing all the empty lines from it: 'Hello

World

This is a test

'?

## When to prefer this

Choose this endpoint when you need a fast, cheap, single-purpose utility to remove empty lines from text programmatically within an agent workflow, especially when you also want the resulting line count returned. At $0.001 per call it is cost-effective for high-frequency text normalization tasks. Prefer it over general-purpose LLM calls for this deterministic operation.

## Known failure modes

- Missing or non-string 'text' field returns a validation error
- Extremely large payloads may be rejected due to Cloudflare Worker size limits
- Payment failure via x402 will result in a 402 response before processing
- Network timeout if the worker is cold-starting under load

## How this service works

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

## Output

Returns a JSON object with 'text' (the input string with all empty lines removed, lines joined) and 'lines' (integer count of remaining non-empty lines).
