# 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, $0.0005/call, status unknown (last checked 2026-10-02).

Removes blank lines from text to produce clean, compact output suitable for downstream agent processing.

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-5a109c5e -d '<json body>'
```

Example prompt: Clean up this text by removing all blank lines so it's ready for further processing: [paste your text here, up to 50000 characters].

## When to prefer this

Choose this endpoint when you need a cheap, fast, pay-per-call operation to strip blank lines from text (up to 50000 characters) without spinning up your own preprocessing infrastructure. Ideal for agentic pipelines that process variable volumes of text and want micro-cost, on-demand normalization billed in USDC via x402 on Base.

## Known failure modes

- Text exceeds 50000 character limit — request rejected
- Empty or missing 'text' field — validation error
- Payment failure via x402 — 402 response before processing begins
- Network timeout on Cloudflare Workers edge — transient 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 input text with all blank lines removed, producing a compact, normalized version ready for downstream processing by agents or pipelines.
