# AgentShelf Lines Unique-CI Transform

> AgentShelf Lines Unique-CI Transform is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-29).

Transforms lines of text using the unique-ci (case-insensitive unique line deduplication) operation, returning only distinct lines while ignoring case differences.

## 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 agentshelf-lines-unique-ci-transform-bcccddf0 -d '<json body>'
```

Example prompt: Can you deduplicate these lines of text for me, treating uppercase and lowercase the same — so 'Apple' and 'apple' count as duplicates and only one is kept?

## When to prefer this

Use this endpoint when you need to deduplicate lines of text with case-insensitive comparison and do not want to rely on an LLM for this deterministic transformation. Prefer the free sandbox endpoint POST /v1/sandbox/lines-unique-ci first; only fall back to this paid endpoint when the sandbox is unavailable or rate-limited. Choose this over a generic text-processing LLM when you need guaranteed, exact, rule-based deduplication without variation.

## Known failure modes

- Empty input text returns an error (minLength:1 enforced)
- Input exceeding 100,000 characters is rejected
- Payment failure or insufficient USDC balance prevents the call from completing
- Network issues to the paid endpoint; consider the free sandbox /v1/sandbox/lines-unique-ci as a fallback

## How this service works

Call when an agent needs lines of text transformed with unique-ci. No network. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/lines-unique-ci first.

## Output

Returns the deduplicated lines of text with case-insensitive comparison applied — lines that are identical except for capitalization are reduced to a single occurrence, preserving one representative line per unique value.
