## When to prefer this

Choose this endpoint when you need a pre-built, validated set of 12 DST boundary test fixtures specifically covering gap and overlap reminder scenarios for Europe and America timezones, and want an immediately downloadable ZIP rather than generating your own synthetic data. Best suited for developers writing explicit reminder gap/overlap policies who want authoritative, versioned fixture cases without manual authoring.

## Known failure modes

- Missing or invalid email format returns validation error
- checkout_key not exactly 64 hex characters causes rejection
- request_id shorter than 16 characters or missing fails validation
- digital_delivery_consent not set to true blocks purchase
- Duplicate request_id with differing parameters may cause conflict
- Payment failure or insufficient USDC balance prevents delivery
- Invalid or expired checkout_key causes authentication failure
