## 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 remove-punctuation-for-agents-3063b152 -d '<json body>'
```

Example prompt: Strip all the punctuation from this text so I can use it for keyword extraction: 'Hello, world! This is a test — isn't it great?'

## When to prefer this

Choose this endpoint when you need a deterministic, first-party punctuation removal step with no API key or subscription overhead. Ideal for agentic pipelines where you want a pay-per-call micro-operation ($0.001 USDC via x402) without standing up custom string-processing code. Best suited for preprocessing steps before tokenization, fuzzy matching, or keyword extraction where consistent, predictable stripping behavior is required.

## Known failure modes

- Text exceeds 100,000 character limit — validation error returned, no charge
- Missing or null `text` field — structured validation error, no charge
- Empty string input — returns empty cleaned text
- Non-string value for `text` — validation error

## How this service works

Remove punctuation from text. Useful before tokenization, keyword extraction, or fuzzy match prep. Returns cleaned text with punctuation stripped, plus a compact receipt. $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

Returns a JSON object containing the cleaned text string with all punctuation characters removed, plus a compact receipt confirming the operation (character counts, processing metadata). No data is retained server-side.
