# AgentShelf Lines Take-5 Transform

> AgentShelf Lines Take-5 Transform is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-11).

Transforms lines of text by applying the 'take-5' operation — selecting or processing every 5th line — locally without network calls.

## 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-take-5-transform-39810324 -d '<json body>'
```

Example prompt: Take this block of text and apply take-5 line sampling to it — I want every 5th line extracted from the full content.

## When to prefer this

Use this endpoint when you need a deterministic, fast, no-network line sampling at a fixed interval of 5 on a text input, and you are willing to pay $0.002 USDC per call. Prefer the free sandbox endpoint /v1/sandbox/lines-take-5 first for testing. Choose this over general-purpose text tools when you specifically need take-5 line selection without LLM involvement.

## Known failure modes

- Input text exceeds 100,000 character limit — request rejected
- Empty or missing text field — validation error
- Payment of exactly $0.002 USDC not provided — 402 Payment Required
- Malformed request body — 400 Bad Request

## How this service works

Call when an agent needs lines of text transformed with take-5. No network. Send JSON {"text":"b\na\n"}. Exact $0.002 USDC on Base. Try unpaid POST /v1/sandbox/lines-take-5 first.

## Output

Returns the input text transformed by the take-5 operation — a subset of the original lines selected at every 5th interval, as a text response.
