# Delx PII Redact

> Delx PII Redact is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-13).

Redacts common personally identifiable information (PII) from text, returning a sanitized version as machine-readable JSON

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 delx-pii-redact-9b8391f4 -d '<json body>'
```

Example prompt: Before you process this user-submitted form, scrub out any PII — names, emails, phone numbers, addresses — so the cleaned text is safe to log and pass downstream: 'Hi, I'm John Smith, you can reach me at john.smith@email.com or 555-867-5309, I live at 42 Oak Street, Springfield.'

## When to prefer this

Choose this endpoint when you need a fast, stateless, deterministic PII scrubbing step with no upstream data leakage — ideal for agent pipelines where the raw text must never reach a third-party provider. Prefer it over LLM-based redaction when you need guaranteed local execution, predictable cost ($0.002/call), and structured JSON output suitable for automated workflows. Best used as a preflight step before logging, prompt injection, or any downstream tool call that will act on untrusted user input.

## Known failure modes

- Validation failure (malformed or missing 'text' field) returns a structured error and is not billed
- Text exceeding 500,000 character limit is rejected
- Ambiguous or novel PII patterns not in the redactor's ruleset may not be caught
- Non-English PII formats may have lower recall
- Payment failure via x402 prevents execution

## How this service works

Redact common PII candidates before logs, prompts, or downstream tools receive the text. Use it before an autonomous workflow acts on untrusted input, changes an API, retries a request, or evaluates production reliability. Returns bounded machine-readable JSON for $0.002 USDC via x402 on Base. Execution is deterministic, first-party, local-only, stateless, and does not call an upstream provider; structured validation failures are not billed.

## Output

Returns a JSON object containing the redacted version of the input text with PII replaced by placeholder tokens, along with metadata about what was found and masked. The response is machine-readable and bounded in structure, suitable for automated downstream consumption.
