## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability finmath-pii-redact-4dafce25 -d '<json body>'
```

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'?

## When to prefer this

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.

## Known failure modes

- 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

## 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.

```json
{
 "text": "John Smith earned $50,000 in Q1 2024 and has a credit card ending in 4532. His phone is 555-0123."
