# Tanod utilpeek Line Tools

> Tanod utilpeek Line Tools is a paid API for AI agents from tanod.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-11).

Applies a configurable pipeline of line-level text operations — trim, dedupe, sort, shuffle, number, and more — to a block of text.

## Facts

- Endpoint: POST https://tanod.dev/v1/text/lines?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402

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 tanod-utilpeek-line-tools-b3312f2b -d '<json body>'
```

Example prompt: Take this list of names, trim whitespace, remove duplicates (case-insensitive), sort them alphabetically using natural sort, and then number each line starting at 1: [paste text here].

## When to prefer this

Choose this endpoint when you need deterministic, composable line-level text transformations — especially when multiple operations (e.g. trim + dedupe + sort + number) need to be applied in a single call. It is purpose-built for line manipulation and supports reproducible shuffling via seed, which general-purpose text APIs typically lack.

## Known failure modes

- Text exceeds 200,000 character limit — request rejected
- operations array empty or missing — validation error
- Invalid enum value in operations or sort_mode — schema validation error
- seed out of range for shuffle — error response
- number_separator longer than 10 characters — rejected

## How this service works

One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.

## Output

Returns the processed text with lines transformed according to the specified operations pipeline. May include numbered lines, sorted/shuffled/deduplicated content, and optionally a frequency count of the most common lines if count_unique is enabled.
