## 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 agent402-tools-dedupe-lines-7779f08d -d '<json body>'

Example prompt: Can you remove all duplicate lines from this list, case-insensitively, and tell me how many were removed? Here's the text: 'apple\nBanana\napple\ncherry\nbanana\napple'

## When to prefer this

Choose this endpoint when you need to quickly deduplicate a block of multi-line text while preserving the original first-seen order. It's ideal for cleaning lists, log outputs, config files, or any newline-delimited data where exact or case-insensitive duplicate removal is needed without sorting or reordering.

## Known failure modes

- Missing or empty text field returns an error
- Extremely large text inputs may be rejected or time out
- Non-string text value causes a schema validation error
- Network or payment failure (x402) prevents the call from completing
