x402

Agentics PII Redaction (x402rail.net) is a paid API for AI agents from x402rail.net, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-15).

Detects and redacts personally identifiable information (PII) from text using one of three modes: remove, mask, or pseudonymize — with a cryptographic attestation of the result.

How this service works

Correctness-critical services for autonomous AI agents

Output

Returns a JSON object containing: the redacted version of the input text, an array of detector labels identifying what PII types were found (e.g. 'email', 'phone'), the redaction mode applied, and a cryptographic attestation object (id, hash, algorithm, public key, signature, detector version, timestamp) plus a URL to retrieve the attestation independently.

Example use cases

Example prompt

“Can you redact the PII from this text using mask mode so emails and phone numbers are partially hidden but still recognizable in format: 'Please contact alice@example.com or call 555-867-0100 to schedule your appointment'?”

Technical details

Endpoint

POSThttps://x402rail.net/v1/redact

When to prefer

Choose this endpoint when you need not just redacted text but also a verifiable cryptographic proof that redaction occurred — ideal for compliance workflows, audit trails, or any pipeline where downstream consumers need to trust that PII was removed. The pseudonymize mode is particularly useful when stable, consistent tokens are needed across multiple documents. Prefer this over generic regex-based redaction when attestation and detector versioning matter.

Side effects

Text exceeds maxContentChars limit from GET /v1/policy — returns an error indicating content is too long
Invalid redactionMode enum value — returns a validation error
Payment not received or x402 payment header missing/invalid — returns 402 Payment Required
Malformed JSON body — returns 400 Bad Request
Service unavailable — returns 5xx error

Input

Schema · Request body

Field	Type	Description
content	string	Text to redact. Capped at the published limit (GET /v1/policy -> limits.extract.maxContentChars).
redactionMode	string	How to replace detected spans: `remove` → `[REDACTED]` (default); `mask` → format-preserving partial masking (e.g. `a*a@ee.com`, `--6789`); `pseudonymize` → stable keyed tokens (`pii_<16 hex>`).
