# LIN Desk Dedupe Lines

> LIN Desk Dedupe Lines is a paid API for AI agents from lin-desk-x402.lindesk.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-11).

Removes duplicate lines from input text, returning only unique lines in order

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 lin-desk-dedupe-lines-c36988fd
```

Example prompt: I have this block of text with a lot of repeated lines — can you deduplicate it and give me back only the unique lines, stripping any whitespace?

## When to prefer this

Choose this endpoint when you need a fast, cheap ($0.001 USDC), no-signup line-level deduplication on plain text up to 100 KiB — especially useful in LLM preprocessing pipelines where repeated lines inflate context windows. Prefer it over custom code when running in a pay-per-call agent environment on Base via x402.

## Known failure modes

- Input text exceeds 100 KiB limit — request rejected
- Missing required 'input' query parameter — 400 error
- Payment not fulfilled via x402 — 402 Payment Required response
- Invalid value for 'strip' or 'ignore_empty' enum parameters — validation error

## How this service works

Pay-per-call API for AI agents: turn any public web page or PDF into clean, LLM-ready Markdown. $0.002 per call in USDC on Base via x402. No API key, no signup.

## Output

A JSON object with op='dedupe_lines', a meta block containing chars_in, chars_out, and elapsed_ms, and a result field containing the deduplicated text with duplicate lines removed (one unique line per original unique line, order preserved).
