How this service works
Mask PII in free text before you send it to an LLM or write it to a log. Pattern-based detection (not ML): emails, phone numbers (Google libphonenumber), IBANs (mod-97), payment cards (Luhn), URLs and IPs. Choose types[] and mode: mask (j***@d***.com, readable), remove, or label ([EMAIL_1], re-identifiable by index). Names and postal addresses are out of scope. The input text is never logged or stored.
Output
Returns the input text with specified PII types redacted according to the chosen mode: 'mask' partially obscures values (e.g. j***@d***.com), 'remove' deletes them entirely, and 'label' replaces them with indexed placeholders (e.g. [EMAIL_1]) for potential re-identification. The input text is never logged or stored by the service.
Example use cases
Sanitize customer support tickets for AI review
“Clean up these support messages before they go to our LLM for auto-response — remove all emails, phone numbers, card numbers, and IP addresses so nothing sensitive leaks into our logs.”
Anonymize payment data in transaction logs
“We're sharing raw transaction logs with our analytics team. Label all the card numbers, IBANs, and URLs in this batch of records so we can re-identify them later if needed, but keep them safe for now.”
Redact PII from user feedback before analysis
“Mask the personal info in these customer feedback messages — emails, phone numbers, everything — but keep them readable so our team can still understand the context when they review them.”

Endpoint
POSThttps://402utils.com/v1/redact?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, deterministic pattern-based PII redaction (no ML inference latency or hallucination risk) for structured PII types: emails, phone numbers (Google libphonenumber), IBANs (mod-97 validated), payment cards (Luhn-checked), URLs, and IPs. Ideal for preprocessing text before LLM calls, sanitizing logs, or compliance workflows. Not suitable for detecting names or postal addresses, which are out of scope.
