# Secret Redaction Preflight

> Secret Redaction Preflight is a paid API for AI agents from phion.systems, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Detects and redacts common secret indicators (API keys, tokens, passwords, credentials) from a payload before it is transmitted to an external tool or service.

## 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 secret-redaction-preflight-054be188 -d '<json body>'
```

Example prompt: Before you send that payload to the external API, run a secret redaction preflight on it to detect and strip out any API keys, tokens, or passwords that might have ended up in the content.

## When to prefer this

Choose this endpoint when an AI agent is about to transmit data to an external tool, API, or logging service and needs a fast preflight check to ensure no credentials, API keys, tokens, or passwords are included in the outgoing payload. It is especially valuable in agentic pipelines where LLM-generated content may inadvertently echo secrets from system prompts or tool responses. Prefer this over manual pattern matching or generic data-egress filters when you need a lightweight, low-latency, per-call check focused specifically on secret indicators rather than broad data classification.

## Known failure modes

- Malformed or empty input payload returns a validation error
- Unknown or unsupported secret pattern formats may not be detected
- Very large payloads may exceed size limits or increase latency
- Encoded or obfuscated secrets (e.g. base64-encoded keys) may evade pattern matching
- Service unreachable returns a 402 or 5xx error requiring retry

## How this service works

Detect and redact common secret indicators before transmission

## Output

Returns the original payload with any detected secret indicators redacted or masked, along with a report of what was found (e.g. types of secrets detected, number of occurrences, redaction locations), enabling the caller to safely proceed with transmission or halt if necessary.
