# PDF Redaction Risk Map — Compute Revenue Lab

> PDF Redaction Risk Map — Compute Revenue Lab is a paid API for AI agents from x402.bakdupoffroad.com, paid per call via x402, $0.045/call, status down (last checked 2026-09-15).

Scans a base64-encoded PDF for sensitive data signals (emails, phone numbers, SSNs, IBANs, credentials, credit cards) and returns a page-level risk map indicating where PII-like patterns were detected before the document is shared or published.

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 pdf-redaction-risk-map-compute-revenue-lab-de2d76b6 -d '<json body>'
```

Example prompt: Can you scan this PDF for any sensitive data like emails, phone numbers, or SSNs before I share it externally? I'll send it as a base64-encoded file — I need to know which pages have risky content.

## When to prefer this

Choose this endpoint when you need a lightweight, privacy-safe PII signal scan on a PDF before sharing, publishing, or archiving it — especially when you want page-level granularity across multiple signal types (email, phone, SSN, IBAN, credentials, credit cards) without sending document text to a third party. Prefer this over general-purpose LLM document analysis when cost predictability ($0.045/call), speed, and the guarantee that customer text is never retained or returned are priorities. Not suitable for full OCR, image-based redaction, or guaranteed complete redaction verification.

## Known failure modes

- PDF exceeds the service's maximum decoded-size limit — request rejected
- Invalid or malformed base64 encoding — parsing error returned
- Payment not provided or insufficient — HTTP 402 returned before processing
- PDF is encrypted or password-protected — content may not be scannable
- Image-heavy pages with no extractable text — flagged as unresolved image pages, signals may be missed
- Network timeout on large documents

## How this service works

Private PDF preflight and authorized-video intelligence APIs paid per call with x402 USDC on Base.

## Output

Returns a JSON object containing a redaction risk map with: per-type signal counts (email, phone, SSN-like, IBAN-like, credential-like, credit card-like), a list of page numbers where signals were found, a list of pages with unresolved image content, a confidence level ('bounded-pattern-scan'), a flag indicating whether the source is safe, a SHA-256 hash of the input document, and the total page count. Also includes economics breakdown of the $0.045 USDC call cost.
