## 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 ciel-m2m-pii-masking-api-c8214041
```

Example prompt: Can you mask any PII in this text before I store it? Here's the content: 'John Smith called us from 555-867-5309, his email is jsmith@example.com and SSN is 123-45-6789.'

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call PII masking step without setting up a dedicated compliance pipeline. Ideal for AI agents that need to sanitize user inputs before passing data to downstream services, logging, or storage. Best suited for single-document or single-string anonymization rather than bulk batch processing.

## Known failure modes

- Empty or missing input text returns an error or empty result
- Malformed JSON request body causes a 400 bad request
- Very long text payloads may time out or be truncated
- Ambiguous or non-standard PII formats may not be detected
- Non-English PII patterns may be missed
- Rate limiting or payment failure via x402 returns 402 or 429

## How this service works

50+ micro-services for AI agents: data parsing, crypto analytics, security scanning, code tools, and more. Pay per call via x402 (USDC on Base) or RapidAPI subscription.

## Output

Returns a JSON object containing the input text with PII values replaced by anonymized placeholders or redaction tokens (e.g. [NAME], [EMAIL], [PHONE]), so the original structure is preserved but sensitive data is removed.
