How this service works
Inspect payload, destination, secrets and size before an agent sends data to a tool or API
Output
Returns a structured preflight decision indicating whether the egress is permitted or blocked, along with a breakdown of any detected secrets, policy violations, destination safety issues, or size limit breaches found in the payload.
Example use cases
Preventing credential leakage before tool call
“Before my agent sends the user record to the CRM API, scan the outbound payload for any secret keys, tokens, or credentials that might have leaked in, and block it if anything looks unsafe.”
Destination safety check for unknown third-party API
“My agent wants to POST some customer data to an external analytics endpoint — can you run a preflight check to confirm the destination URL is acceptable and the payload doesn't contain anything it shouldn't be sending?”
Enforcing size and secret policy in automated pipeline
“We have an automated pipeline that sends batches of records to external services — run an egress preflight before each outbound call to make sure the payload size is within limits and no secrets are embedded in the data.”
Technical details
Endpoint
POSThttps://phion.systems/v1/paid/trust/data-egress-preflightWhen to prefer
Use this endpoint when an AI agent is about to send data to an external tool or API and you need a lightweight, pre-transmission safety gate — especially when the payload may contain user data, secrets, or credentials that should not leave the system. Prefer this over manual auditing or post-hoc logging when you need a real-time block/allow decision before egress occurs.
Side effects
- Malformed or empty input schema may return a validation error
- Destination URL not parseable results in a rejection
- False positives on secret detection for non-sensitive patterns resembling keys
- Payload too large to inspect may time out or be rejected
- Ambiguous policy configuration may yield inconsistent verdicts
