How this service works
Paid tools for AI agents over x402: a PII and secret guardrail that scans outbound payloads, live citable data (crypto, weather, GitHub, sports, FX), and an RCP/1 retrieval server backed by that live data.
Output
Returns a JSON object with: overall pass/fail verdict, a 0–100 risk score, a human-readable summary, a sanitized copy with sensitive values replaced by labeled tokens, and a per-framework breakdown (pci-dss, gdpr, hipaa, secrets) listing each triggered rule, its count, label, and severity (critical/high/medium/low). Also includes engine version, character count, and x402 payment settlement metadata.
Example use cases
Pre-send outbound webhook guardrail
“I'm about to POST this JSON object to our partner's webhook endpoint — can you scan it for any credit card numbers, SSNs, or AWS keys first, and show me a sanitized version I can safely send?”
LLM output compliance check
“Before my agent forwards the customer support summary to our CRM, audit the text for GDPR and HIPAA violations — I need to know the risk score and whether it's safe to send as-is.”
Log sanitization before storage
“We're about to write this application log blob to S3 — can you run it through a secrets and PCI-DSS scan to make sure there are no credentials or card numbers hiding in it, and give me a redacted copy?”
Technical details
Endpoint
POSThttps://pii-guardrail.chronokey.workers.dev/v1/audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a multi-framework compliance audit (PCI-DSS, GDPR, HIPAA, and secrets) in a single call with a sanitized output ready to forward. It is specifically designed for AI agent pipelines that need a guardrail before sending data to external services, logging systems, or third-party APIs. Prefer it over generic regex-based scrubbers when you need structured per-framework verdicts and severity ratings, or when you need a redacted payload rather than just a detection report.
Side effects
- Text exceeds 32,000 character limit — request rejected
- Both 'text' and 'payload' provided simultaneously — mutually exclusive fields
- Invalid framework enum value — request rejected with validation error
- Payment via x402 not settled — endpoint returns 402 Payment Required
- Malformed JSON in payload field — parse error returned
- Network timeout from Cloudflare Worker — transient 5xx error
