How this service works
Deterministic finance and crypto math for AI agents: TradFi (NPV, IRR, XIRR, Black-Scholes + Greeks, bonds, VaR, Sharpe) and DeFi (impermanent loss, perp liquidation, funding, Uniswap v3, health factor, cost basis). Exact, model-free arithmetic that LLMs get wrong — priced per call in USDC.
Output
Returns a JSON object with a 'result' field containing the sanitized text with PII replaced or masked, and a 'meta' field with processing metadata such as what was redacted.
Example use cases
Example prompt
“Can you redact any PII from this text before I store it: 'John Smith called from 555-867-5309, his SSN is 123-45-6789 and he lives at 42 Maple Street, Boston MA'?”
Technical details
Endpoint
POSThttps://finmath.qzqh5rrbkz.workers.dev/v1/pii_redact?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need deterministic, server-side PII redaction before passing text to downstream systems, logging pipelines, or AI models — especially when you cannot trust LLM-based redaction for compliance purposes. It is priced per-call at $0.002 USDC and suited for automated agent workflows requiring reliable anonymization.
Side effects
- Missing 'text' field in request body returns a validation error
- Empty string input may return unchanged or minimal result
- Very long text inputs may hit worker payload limits
- Network timeout if Cloudflare Worker is overloaded
- Payment failure (402) if USDC balance is insufficient for the $0.002 per-call charge
