## 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-counter-chars-words-lines-bytes-86c57af4
```

Example prompt: Count the words, characters, lines, and UTF-8 bytes in this text: 'The quick brown fox jumps over the lazy dog.'

## When to prefer this

Use this endpoint when you need fast, precise text statistics (character, word, line, and byte counts) for a string — especially useful for validating text against LLM token/character limits, checking content lengths before storage or API submission, or gathering basic readability metrics. Prefer this over client-side counting when operating inside an agent pipeline where a trusted, server-side count is needed.

## Known failure modes

- Missing required 'input' query parameter returns an error
- Input text exceeding 100 KiB limit may be rejected
- Non-text or binary input may produce inaccurate counts
- Payment failure (402) if USDC payment on Base is not completed

## 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

Returns a JSON object with the operation name ('count'), metadata (chars_in, chars_out, elapsed_ms), and a result object containing: chars (character count), lines (line count), words (word count), and bytes_utf8 (UTF-8 byte size of the input text).
