How this service works
Redact PII from text before it is stored or logged. Returns redacted text plus exact byte spans and counts per class: credit_card, iban, email, private_key, evm_address, phone, ipv4, url.
Output
Returns the sanitized text with all matched PII replaced by the placeholder template, along with a list of exact byte-offset spans for each redacted item and per-class counts (e.g. how many credit_card, email, phone matches were found).
Example use cases
Sanitize logs before storage
“We're about to store these raw API request logs in our database. Can you scrub any PII — emails, IPs, phone numbers, credit card numbers — before they get written? Use [REDACTED:{cls}] so I can see what was removed.”
Anonymize LLM training data
“I have this batch of user messages I want to use for fine-tuning, but I need to remove all personal info first. Redact emails, EVM wallet addresses, private keys, IBANs, and phone numbers from this text before I use it.”
GDPR-safe support ticket archiving
“Before we archive this support ticket thread, please redact all sensitive fields — credit card numbers, IBANs, email addresses, and phone numbers — so the archived version is GDPR-compliant. Tell me how many of each type were found.”
Technical details
Endpoint
POSThttps://api.maximusmediahouse.com/v1/redact?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need deterministic, rule-based PII removal with exact byte-span provenance — particularly before storing, logging, or forwarding text that may contain credit card numbers, IBANs, emails, private keys, EVM addresses, phone numbers, IPv4s, or URLs. Prefer this over LLM-based redaction when you need reproducible results, audit trails, and per-class counts rather than probabilistic detection.
Side effects
- Text exceeds 100,000 character limit — returns a 400 error
- Invalid PII class name in 'classes' array — may return 400 or silently ignore unknown class
- Malformed placeholder template — may produce unexpected output strings
- Very ambiguous text may produce false positives or miss obfuscated PII
- Empty text input returns empty redacted text with zero counts
