## 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 retention-deletion-receipt-55b6906c -d '<json body>'
```

Example prompt: Sign a deletion receipt for my declared action — we purged user records from the analytics database at this timestamp — and give me the verifiable attestation I can include in our compliance audit log.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
