How this service works
Sign a declared retention or deletion action
Output
A cryptographically signed receipt confirming the declared retention or deletion action, including a timestamp, action type, and verifiable attestation that can be stored for compliance audits or shared with auditors as tamper-evident proof.
Example use cases
GDPR deletion compliance proof
“We just deleted all personal data for user account 8821 from our system as required. Can you sign a deletion receipt so I have a verifiable record to show in our GDPR audit?”
Retention policy action attestation
“Our data retention policy says we keep transaction logs for 7 years — sign a receipt attesting we applied that retention rule to the Q1 2024 transaction dataset so we have a tamper-evident compliance record.”
Agent data lifecycle audit trail
“My AI agent pipeline just completed a scheduled purge of cached user context. Generate a signed deletion receipt for that action so the event is logged with a cryptographic attestation for our trust audit.”
Technical details
Endpoint
POSThttps://phion.systems/v1/paid/trust/retention-deletion-receiptWhen to prefer
Choose this endpoint when an AI agent or automated pipeline needs a signed, verifiable proof that a data retention or deletion action was declared and executed — particularly for compliance workflows (GDPR, CCPA, internal data governance), audit trail generation, or trust handoffs between agents. Prefer this over generic logging when tamper-evidence and cryptographic signing are required.
Side effects
- Missing or malformed action declaration payload returns a validation error
- Undeclared or unsupported action type may result in rejection
- Payment failure via x402 prevents receipt generation
- Network timeout before signing completes leaves no receipt issued
- Duplicate submissions for the same action may not be deduplicated, consuming credits without idempotency guarantees
