payable, partial

BitBooth PII Redact: pay 0.002 USDC, strip emails, phones, SSNs, credit cards, IPv4 addresses, and hex-looking secrets from a text blob before passing it to an LLM. Compliance primitive for agents in regulated industries (health, finance, legal). Pure regex — no LLM inference, deterministic output. Pairs with /v1/cdp/prompt-injection-scan as the sanitize-before-model pipeline.
