Usage

curl -X POST https://pii-redactor-formatho.filesformatho.workers.dev/api -H 'Content-Type: application/json' \
  -d '{"text":"Contact jane.doe@corp.com or +1 (415) 555-0132. Card 4111 1111 1111 1111."}'

Detects and redacts emails, phone numbers (NANP & international), credit cards (Luhn-verified, so order numbers survive), SSNs, IBANs (mod-97 verified) and IPv4 addresses. Two modes: redact (replace with [EMAIL]-style tokens) or mask (fixed-length ****). Filter with types=email,ssn; get match offsets with include_positions=true. Overlapping candidates resolve to the longest, most specific match.

Prefer POST for real documents — GET query strings can land in server logs. Redaction runs in-memory at the edge; matched values are never echoed back or stored.

Full parameter reference: /api endpoint.

Privacy-first: the text never leaves memory — no logs, no storage, no telemetry, and detection results contain counts/offsets only, never the PII itself.
