# Web2Markdown Text Truncate API

> Web2Markdown Text Truncate API 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).

Truncates a text string to a specified character limit, optionally appending an ellipsis, returning character counts and elapsed time.

## 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 web2markdown-text-truncate-api-30f4cf0d
```

Example prompt: Truncate this text to 500 characters and add an ellipsis at the end: 'Artificial intelligence is transforming industries worldwide, from healthcare to finance, enabling automation of complex tasks that previously required human expertise...'

## When to prefer this

Choose this endpoint when you need a fast, stateless, pay-per-call text truncation with precise character counting and optional ellipsis — especially when integrating into AI agent pipelines that need to stay within character budgets without standing up your own string-processing logic or managing API keys.

## Known failure modes

- Missing required 'input' query parameter returns an error
- Input text exceeding 100 KiB limit may be rejected
- Invalid max_chars value (non-integer string) may cause a validation error
- Payment failure via x402 protocol results in 402 response before processing
- Network timeout on the Cloudflare Worker edge

## 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 the operation name ('truncate'), a meta object containing chars_in (original character count), chars_out (truncated character count), and elapsed_ms (processing time in milliseconds), plus a result field with the truncated string (with optional ellipsis appended).
