## 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 character-word-count-for-agents-b05bd743 -d '<json body>'
```

Example prompt: How many characters and words are in this text: 'The quick brown fox jumps over the lazy dog. Pack my box with five dozen liquor jugs.'?

## When to prefer this

Choose this endpoint when you need a fast, deterministic, first-party count of characters, words, lines, and bytes without relying on client-side logic or LLM estimation. Ideal for pre-flight checks before SMS sending, prompt truncation, token budget estimation, or content length validation. No API key or subscription required — pay $0.001 USDC per call via x402 on Base.

## Known failure modes

- Text exceeds 100,000 character limit — structured validation error returned, no charge
- Empty or missing text field — validation error
- Malformed JSON request body — 400-level error
- Payment not included or insufficient — x402 payment required response

## How this service works

Count characters, words, and lines. Call before truncating prompts, validating SMS length, or estimating token budget from raw text. Returns character, word, line, and byte-oriented counts in one JSON object. $0.001 USDC per successful call via x402 on Base—deterministic first-party JSON, no API key, no subscription, and nothing is billed on structured validation errors.

## Output

A JSON object containing numeric counts for characters, words, lines, and bytes derived from the submitted text. All metrics are returned in a single response with no data retained.
